DMC 2000TD OPERATORS MANUAL 1 Introduction This manual provides operation and operator’s maintenance information for the Radiation Safety & Control Services Inc. (RSCS) DMC 2000S Training Device (DMC 2000TD). The DMC 2000TD is a fully functioning simulated replica of the Mirion Technologies (MGP Instruments) DMC 2000S Electronic Dosimeter. The manual provides both instruction for the DMC 2000TD and the Simulation Control Center (SCC) software used to wirelessly control the DMC 2000TD. It is meant for the trainer’s reference and should not be used in place of the standard DMC 2000 manual. It is strongly suggested that both the trainer and trainee fully familiarize themselves with the standard DMC 2000 manual before reading this manual. 1.1 Brief Description of RSCS Simulation System Architecture The most basic level of the simulation system developed by RSCS Inc. consists of the Simulation Control Center (SCC) software, operating on a tablet with a USB Dongle installed, and at least one simulated training device. The SCC software and training device communicate with each other wirelessly over a proprietary IEEE 802.15.4 network through the USB Dongle. This communication allows a training instructor to remotely control simulated gamma radiation levels as observed by a trainee operating the connected device. The simulation system provides for the interoperability of multiple control devices and training devices to be used in close proximity. Any SCC software application is capable of controlling one or more training instruments. This flexibility allows one or more instructors to instruct multiple students using different training instruments simultaneously. Once a device has been connected to a specific control device it may no longer be seen by or connected to another SCC application even if another is within range, until the control device has released control. 1.2 Simulation Control Center The Simulation Control Center (SCC) software application was developed to run on any Windows 8.1TM tablet or computer. Combined with the provided USB Dongle the SCC allows a training instructor to remotely observe and send commands to multiple DMC 2000TDs simultaneously. In addition to remotely controlling simulators SCC allows the user to configure specific device settings and update device firmware. 1.3 DMC 2000S Training Device The DMC 2000S Training Device (DMC 2000TD) is a fully functioning simulated DMC 2000S personal electronic dosimeter that is capable of simulating almost all of the major features and functions of the standard DMC 2000S. It may be configured by the user to match almost any configuration used in the standard DMC 2000S. 1.4 Items Supplied The DMC 2000TD may be supplied individually for use with existing Windows 8.1TM computers or Tablets, or with a preconfigured tablet. If the DMC 2000TD is supplied without a Windows 8.1TM tablet, the user must download the SCC application from the Windows App StoreTM. In addition to the SCC application the system requires the use of an RSCS, Inc. supplied USB Dongle for communication purposes.1 REVISION 0
DMC 2000TD OPERATORS MANUAL 1 DMC 2000TD 1.5 DMC 2000TD Major Characteristics The DMC 2000TD has been designed to match both the environmental and electrical characteristics of the standard DMC 2000S as closely as possible. Therefore, it has been designed for use in the following environments: • Office and Laboratory environments • Industrial environments • Hospitals • Military environments (including dockyards and shipping – excluding exposure to salt water and extremes in military environments. The major physical characteristics of the DMC 2000TD are listed in Table 1. External features are shown in Figure 1 and outlined in Table 2.

DMC 2000TD OPERATORS MANUAL 1.6 Preparation for Use/Getting Started The following section describes the general process for setting up the DMC 2000TD for use. For specific instructions on preparing the SCC application for use see section 2.2.3. 1.6.1 Setting Up The initial set up process for the DMC 2000TD is very simple and almost exactly the same as that used for the standard DMC 2000S. Setting up is primarily composed of: • Unpacking the DMC 2000TD • Inserting the battery (if not already installed) • Checking the initialization sequence • Checking the default settings Unpacking the DMC 2000TD There are no special unpacking instructions. Depending upon customer requirements the DMC 2000TD may, or may not be shipped with a battery and/or clip assembly. The battery, if supplied will be a 3 V CR2450 Lithium battery. The DMC 2000TD Battery WARNING Keep away from small children. Do not swallow. Not rechargeable. Do not throw in fire. General Instructions and Precautions Always use new undamaged batteries of the correct type. Inserting/Replacing the DMC 2000TD Battery The DMC 2000TD is supplied with the standard Mirion Technologies (MGPI) battery cover. Therefore, the same battery installation/removal procedure as the standard DMC 2000S should be used. 1. Read and observe the General Precautions and instructions at the beginning of this section. If necessary remove the battery cap from the case as described in steps 2 through 8 below. 2. Switch the DMC 2000TD to *Off*. 3. Remove the DMC 2000TD clip if attached. 4. Using a standard DMC 2000S battery key (or if unavailable, using a screwdriver), unscrew (counterclockwise) the battery cover. 5. Take Off the battery cover and remove the battery. Note: Due to the presence of a capacitor to maintain power during battery removal, the DMC 2000TD LCD will display *Off* for a period of time even after battery removal. Once the capacitor has dissipated, the LCD will clear. 6. Take a piece of cotton cloth to handle the battery, in order to avoid the superficial oxidation of the housing stainless steel or the cover. 7. Insert a new battery in the housing (with the “+” side of the battery placed towards the front of the dosimeter). Note: Use caution not to over torque the battery cover. Hand tight plus ¼ turn is recommended. 5 REVISION 0
DMC 2000TD OPERATORS MANUAL Figure 2 External View with Battery Removed Start-up Sequence Due to the constraints of simulation, the DMC 2000TD has a modified version of the DMC 2000’s “Pause” Mode. After battery replacement, the DMC 2000TD will display “*Off*” instead of the DMC 2000’s “Pause”. Initial Battery Insertion or the “Off” State When a battery is inserted into the DMC 2000TD for the first time or when the unit is in the powered down state, indicated by “*Off*” on the LCD, insertion of a new battery will not be indicated in a manner other than the LCD displaying or continuing to display “*Off*”. Battery Changes in the “On” State When changing the battery while the DMC 2000TD is in the “On” state, upon loss of battery contact, the DMC 2000TD will activate the “batlo” alarm until a battery regains contact or the capacitor dissipates completely. Once the battery is replaced, the DMC 2000TD will display “*Off*” and no longer be in “On” state. Wearing a DMC 2000TD The DMC 2000TD should be worn in the same manner as the standard DMC 2000S to ensure proper training. For most operating conditions, it is recommended that the DMC 2000TD be worn on the outside of any protective clothing (see Figure 3). Note that the button should be facing outwards. REVISION 0 6
DMC 2000TD OPERATORS MANUAL Similar to the standard DMC 2000S, wearing the DMC 2000TD outside of protective clothing offers the advantage of allowing the user to read the DMC 2000TD’s LCD display and operate the button as required. Typically, the DMC 2000TD should be worn on the chest or the waist. The type of outer protective clothing will determine how the DMC 2000TD is attached (i.e. the DMC 2000TD clip or a lanyard). For example, if the protective clothing has no breast pocket (or the use of a belt is prohibited) the lanyard may be the most practical method of wearing the DMC 2000TD.

DMC 2000TD OPERATORS MANUAL 1.7 Functional Description and Operating Instructions The following chapter explains the basic functions performed by the DMC 2000TD and the functions of the SCC software application when used to control the DMC 2000TD. It also instructs both the trainer and the trainee in the functions that will allow them to send commands from SCC, display data on devices, acknowledge alarms and general operation of each device. For basic functions and operations of SCC, please refer to Chapter 2 The chapter has the following two sections: • Wireless Network Configuration • DMC 2000TD Functional Description and Operation 1.7.1 Wireless Network Configuration This section provides a brief technical overview of the current network configuration used by the SCC software application and the associated simulators. It explains the two basic options available for controlling DMC 2000TDs and other simulators remotely using the SCC application. The two basic options when using the network are: • Normal Mode • Group Mode A basic understanding of these wireless network configurations and the functions of each device within the network allows an instructor to configure the training methods and scenarios to provide the most realistic training possible. Normal Mode The Normal Mode is the basic means of controlling and interacting with a single training device or multiple training devices all being controlled individually, or simultaneously, depending upon trainer preference. It is the default option when searching for and connecting to a device using the SCC. This mode allows the trainer to continuously adjust the connected device(s) measurement values, activate simulated alarms and other features, as well as monitor the current status indications being displayed on the device(s). Group Mode Group Mode incorporates all the features of Individual Control Mode while allowing SCC to provide the same control inputs to different groups of multiple training devices at the same time. This mode allows the trainer to create groups of devices and provide the same inputs, e.g. dose rate levels, to all the devices within a group at once. SCC is capable of connecting and controlling up to thirty-two (32) different devices at one time. This total may be reached in any manner the instructor chooses so long as the number of controlled units does not exceed thirty-two (32). 1.8 DMC 2000TD Functional Description and Operation 1.8.1 DMC 2000TD LCD Display The same custom-designed LCD display as the standard DMC 2000S is used by the DMC 2000TD. This display provides a visual interface for viewing simulated dose and other simulated DMC data. The DMC 2000TD display is illustrated in Figure 4. REVISION 0 8

The DMC 2000TD can be used in two different operating modes: the “autonomous” mode and the “Satellite” Mode. The mode selection can be set using the DMC 2000TD Configurations feature of SCC (see 2.3.2). 1.9.1 Autonomous Mode In Autonomous mode, the DMC 2000TD is capable of entering and exiting Active Mode without the use of the SCC application. 1.9.2 Satellite Mode In Satellite Mode, the DMC 2000TD enters Measurement Mode via the SCC application. All configured functions are controlled by the SCC application. 1.9.3 DMC 2000TD Function Mode Regardless of the operating mode, the DMC 2000TD has various function modes. • Off • Pause • Active/Measurement 9 REVISION 0
DMC 2000TD OPERATORS MANUAL 1.9.4 Off Mode When in this mode, the DMC 2000TD: • Permanently displays the message “*Off*”. • Periodically monitors the battery status. In this mode the DMC 2000TD uses minimal power consumption. No simulation functions or SCC connections are available in this configuration. 1.9.5 Pause Mode When in this mode, the DMC 2000TD: • Periodically monitors the battery status • Permanently displays the message “Pause” or a personalized message of 6 characters or less if configured • Attempts to connect with any available Control Devices (if unconnected) In this mode the DMC 2000TD simulates all the selected features and functions of a standard DMC 2000S Pause Mode operation. During this state the DMC 2000TD does not accumulate dose and allows for limited changes initiated from the SCC application. All networking and major functions of the SCC application are available to the trainer when in Pause Mode. Note: The personalized message displayed in Pause Mode can be set DMC 2000TDin the SCC Device Configuration. 1.9.6 Active/Measurement Mode When in this mode, the DMC 2000TD: • Communicates with the SCC application for all selected features • Audible and Visual signals activate when commanded • Periodically monitors the battery status • Attempts to connect with any available Control Devices (if unconnected) In this mode the DMC 2000TD simulates all the selected features and functions of a standard DMC 2000S Measurement Mode operation. During this state all functions of the simulator and SCC are available to the trainer. 1.10 Start-Up To start up a DMC 2000TD the following procedures must be performed: • A short press of the DMC 2000TD button to exit “*Off*” mode • Configuration using SCC Device Configurations (definition of alarm threshold values, dose rate display authorization, alarm rate authorization, alarm duration…) • Activation A connection with the SCC application is required for full operation of the DMC 2000TD in all modes.

DMC 2000TD OPERATORS MANUAL 1.15 Maintenance This section describes the maintenance that may be required for the DMC 2000TD. Maintenance is limited to general cleaning, removing/replacing the DMC 2000TD battery and removing/replacing the DMC 2000TD clip assembly. Limited maintenance may also be carried out to check the functionality of the DMC 2000TD. 1.15.1 The DMC 2000TD Battery If the DMC 2000TD is to be stored for a prolonged period of time the DMC 2000TD battery should be removed. There is no recommended maximum battery installation period. If there is any uncertainty of when the DMC 2000TD will be used next the battery should be removed for storage. 1.15.2 Replacement Batteries Replacement batteries must be suitable for installation into the DMC 2000TD. On no account must excessive force be used to insert the battery into its compartment. The following are recommended replacement batteries: Renata - LiMnO2 / 3V/ CR 2450 Detailed procedures for inserting/replacing the DMC 2000TD battery are given in Section 1.15.1. 1.15.3 Cleaning The DMC 2000TD is a sealed unit and has protection against dust and low pressure jets of water from all directions. The unit will not withstand prolonged immersion under pressure. Cleaning should be carried out if the unit requires general cleaning or if the DMC 2000TD battery has leaked. 1.15.4 General Cleaning The unit should be cleaned with a damp cloth. Use a neutral water-based detergent, other detergents may damage or attack the DMC 2000TD outer plastic coating. A small brush should be used to clean any crevices in the case. After cleaning dry the DMC 2000TD with a soft cloth. During cleaning, water may enter the alarm sounder aperture. The sounder aperture is watertight, although water ingress may deaden the alarm. Any water should be shaken or blown out of the sounder aperture to restore the alarm noise level. 1.15.5 Cleaning after a Battery Leakage Any leakage of the DMC 2000TD battery must be treated with extreme caution. In most instances battery leakage will be confined within the DMC 2000TD battery compartment. Minor leakage (light smearing) may be removed with a cotton swab moistened with a water-based detergent. However, if doubt exists as to the extent of the leakage the DMC 2000TD should be considered as unusable and RSCS should be contacted for advice. 1.15.6 Periodic Cleaning The DMC 2000TD should be cleaned by wiping it over periodically with a cloth lightly dampened with a solution of water and up to 5% of a neutral water-based detergent.

DMC 2000TD OPERATORS MANUAL 2 Simulation Control Center 2.1 Introduction The Simulation Control Center (SCC) is an application written and designed for use with Windows 8.1TM. SCC can be installed on any Windows 8.1TM Tablet and downloaded for free, directly from the Windows Store. SCC allows a training instructor to remotely send commands wirelessly to a variety of simulated radiation detection instruments. This section focuses on the use of SCC with the DMC 2000TD. SCC is designed for touchscreen use with an intuitive layout for quick and easy control of one or multiple DMC 2000TDs. The Simulation Control Center (SCC) utilizes a USB Dongle containing an IEEE 802.15.4 wireless module that allows for the individual control of up to thirty-two (32) devices connected at one time. 2.2 Functional Description 2.2.1 General The Simulation Control Center (SCC) application provides the user a means of wirelessly controlling the features and functions of a connected DMC 2000TD. The SCC application runs on any Windows 8.1TM Tablet and communicates wirelessly via a USB Dongle inserted in the Tablet. SCC provides the user with vital information about any currently connected DMC 2000TDs. It also provides the user a means of navigating between Training, Control, and Configuration of DMC 2000TDs. 2.2.2 Hub Page The Hub Page (Figure 50) is the basic interaction point between SCC and DMC 2000TDs awaiting control or configuration. The Hub Page consists of two main Sections; Training and Device Configuration. Training allows the user to directly connect with DMC 2000TDs and simulate almost all functions of a real DMC 2000S dosimeter. Device Configuration allows the user access to the various configurable options of the DMC 2000TD, similar to Mirion Technologies DosiMass or DMC User software. Figure 50 SCC Hub Page 2.2.3 Preparations for Use The Simulation Control Center (SCC) application runs on any Windows 8.1TM Device. SCC comes preinstalled on the specific Windows 8.1TM Device purchased. Ensure the USB Dongle is installed in the USB port of the Windows 8.1TM Device. 29 REVISION 0
DMC 2000TD OPERATORS MANUAL Note: The USB Dongle must be connected to the Device for communication with the DMC 2000TDs. Once installed, SCC requires no preparation for use other than opening the application. 2.3 Operating Instructions The following section provides operating instructions for the Simulation Control Center (SCC). These instructions are specific to the DMC 2000TD only. Specific instructions for other simulator device types can be found in the device specific section of each manual. 2.3.1 Starting the Simulation Control Center Application The Simulation Control Center runs as an application on a Windows 8.1TM Device.

SCC will no longer show the DMC 2000TD Tile(s) that went to Off Mode. The Presets and dose rate information will be grayed out. Note: Once a DMC 2000TD is switched to Off Mode, it can no longer be controlled by SCC and require a Selector Button push to become available for connection again. Changing Simulated Dose Rates One of the main functions of the DMC 2000TD is the ability to simulate dose equivalent rates. This allows an instructor to train individuals about safe work practices in ever changing environments. The DMC 2000TD receives a simulated dose rate from the SCC application and remains at that dose rate until a new command is sent from SCC adjusting the dose rate or Function Mode. Three (3) options are available for controlling the simulated dose rate of the DMC 2000TD(s); Presets, Direct Number Input, and a Slide Scale. Refer to “Dose Rate Control Options”. To change the simulated dose rate of a DMC 2000TD; 1. Ensure the DMC 2000TD(s) is in Active Mode. 65 REVISION 0
DMC 2000TD OPERATORS MANUAL 2. Select the DMC 2000TD(s) to send a simulated dose rate to. 3. Using one of the three (3) methods of selecting a simulated dose rate value, choose the value to send (see “Dose Rate Control Options”). REVISION 0 66
DMC 2000TD OPERATORS MANUAL 4. When the value is selected, SCC will automatically send that value to the DMC 2000TD(s). 5. To adjust the DMC 2000TD(s) to another simulated dose rate value, employ one of the three (3) options for changing the dose rate value. 67 REVISION 0
DMC 2000TD OPERATORS MANUAL 6. Returning the simulated dose rate value to zero (0) will stop the DMC 2000TD from continuing to accumulate dose. Alarms During Configuration (see section 2.3.2) each DMC 2000TD is setup with alarm thresholds for the following categories; Dose Alarm, Dose Rate Alarm, and Time Alarm (if desired). Each of these alarms has unique characteristics that will trigger the alarm. Refer to section 1.12 for details on how a DMC 2000TD Hardware Alarm is displayed and the sound characteristics associated with the alarms on the DMC 2000TD. Dose Alarm A Dose Alarm is triggered when a DMC 2000TD has accumulated enough simulated dose to exceed the preconfigured threshold. 1. Dose Equivalent Pre-Alarm (Warning) If properly configured, the DMC 2000TD will have a Dose Alarm that acts as a warning to a true Dose Alarm. With a simple Selector Button push on the DMC 2000TD, the warning alarm will be silenced however the light will still flash and a warning symbol is shown on the display. SCC displays a Dose Pre-Alarm warning as a yellow dot next to the Dose Alarm Threshold of the DMC 2000TD Tile. REVISION 0 68
DMC 2000TD OPERATORS MANUAL 2. Dose Equivalent Alarm The DMC 2000TD will have a Dose Alarm when the accumulated dose exceeds the preconfigured threshold. This alarm cannot be silenced and will only end when the DMC 2000TD Function Mode is switched to Pause or Off. Alternatively, using the Zero Dose feature of SCC will end a Dose Alarm (if the alarm is not set to zero (0)). SCC displays a Dose Alarm as a red dot next to the Dose Alarm Threshold of the DMC 2000TD Tile. Note: A combination of Dose and Dose Rate Alarms (and Pre-Alarms) are possible on a DMC 2000TD. In this scenario, SCC will display a colored dot (depending on alarm type) next to corresponding threshold. 69 REVISION 0
DMC 2000TD OPERATORS MANUAL Dose Rate Alarm 1. Dose Equivalent Rate Pre-Alarm (Warning) If properly configured, the DMC 2000TD will have a Dose Rate Alarm that acts as a warning to a true Dose Rate Alarm. With a simple Selector Button push on the DMC 2000TD, the warning will be silenced however a warning symbol will still be displayed. If the dose rate is lowered below the Dose Rate Pre-Alarm threshold, the warning will end. SCC displays a Dose Rate Pre-Alarm warning as a yellow dot next to the Dose Rate Alarm Threshold of the DMC 2000TD Tile. 2. Dose Equivalent Rate Alarm The DMC 2000TD will have a Dose Rate Alarm when the dose rate exceeds the preconfigured threshold. This alarm will only end when the dose rate is below the threshold again, or the Function Mode of the DMC 2000TD is switched to Pause or Off Mode. Note: If a DMC 2000TD is configured for Rate Alarm Latch, a Rate Alarm will not end when the dose rate goes below the threshold again. REVISION 0 70
DMC 2000TD OPERATORS MANUAL SCC displays a Rate Alarm as a red dot next to the Dose Rate Alarm Threshold of the DMC 2000TD Tile. Note: A combination of Dose and Dose Rate Alarms (and Pre-Alarms) are possible on a DMC 2000TD. In this scenario, SCC will display a colored dot (depending on alarm type) next to corresponding thresholds. Time Alarm If properly configured, a DMC 2000TD can have a Time Duration Alarm or a Time Remaining Alarm. Neither of these alarms is shown in SCC as they are Hardware Alarms configured directly in the DMC 2000TD and work exactly as a real DMC 2000S Time Alarm. Simulated Faults and Alarms Each DMC 2000TD has the ability to simulate eleven (11) Faults or Alarms that a real DMC 2000S could have in use. These Faults are each described in section 1.13 and work exactly as a real DMC 2000S fault or alarm. Each DMC 2000TD is preconfigured with ten (10) of these Alarms that cannot be user configured. The only configurable alarm is the Low Battery Alarm (see section 2.3.2 Configurations) 71 REVISION 0
DMC 2000TD OPERATORS MANUAL All eleven (11) simulated alarms are only activated on the Control Page using the App Bar Alarms feature. Note: Each DMC 2000TD has the ability to display a Low Battery Alarm (*BaLo*) upon actual low battery voltage. Autonomous Mode Each DMC 2000TD has the ability work in Autonomous Mode like a real DMC 2000S. Autonomous Mode is set in Configurations (see section 2.3.2) A DMC 2000TD configured for Autonomous Mode will maintain the same functionality as a DMC 2000TD in Satellite Mode except for the option to control some Function Modes with the Selector Button. In Autonomous Mode, a DMC 2000TD is capable of switching from Pause Mode to Active Mode using the Selector Button.
