![14 3.1.2. Keys & Interface The MicroRAE has two keys: MODE Y/+ In addition to their labeled functions, the keys labeled [MODE] and [Y/+] act as “soft keys” that control different parameters and make different selections within the instrument’s menus. From menu to menu, each key controls a different parameter or makes a different selection. In addition to the functions described above, either key can be used to manually activate display backlighting. Press a key when the backlighting is off to turn it on. 3.2. Screen Display For Various Numbers Of Active Sensors The MicroRAE can accommodate from one to four sensors. When one or more sensors is either not installed or turned off, the display only shows the installed, active sensors:](https://usermanual.wiki/RAE-Systems/2601/User-Guide-2951316-Page-14.png)
![15 3.3. Menus The reading menus are easy to step through by pressing the [MODE] and [Y/+] key. * If the MicroRAE is WiFi equipped: WiFi-equipped instruments can receive up to five messages. If a message has been received by the MicroRAE, the number of messages is displayed (1 MSG, etc.). The display shows the message sequentially, cycling through the message each half-second. The Message number, “page” of the message (it automat-ically breaks a message across screens), and received time and date are shown. Up to five messages can be received by the MicroRAE. Pressing [MODE] Steps through the messages. When “Exit” is shown, press [Y/+] to return to the Main Display. Note: In most cases, if no buttons are pressed at any of the menu steps for 60 seconds, the instrument reverts to the main display. *](https://usermanual.wiki/RAE-Systems/2601/User-Guide-2951316-Page-15.png)
![16 3.4. Glance Mode If you want to check your instrument’s configuration and it is turned off, you do not have to turn it on. Press and hold [Y/+] until the screen illuminates and shows the configuration. This tells you the installed sensors: Press [Y/+] to advance through screens that tell you if the radio is on, BLE is on, GPS is on, WiFi is on, etc. These change, depending on the instrument’s configuration. To exit, press [MODE], and the display shuts off. Note: If you do not press a button for 60 seconds, it turns off automatically. 3.5. Panic Alarm Press and hold [Y/+] at any time to trigger the Panic Alarm. The display shows “PANIC ALARM” and sends a message to the Location Manager or ProRAE Guardian. (Note: Use ProRAE Studio II to define information and its prioritization for viewing.) In addition, the instrument alarms (audible and visible) four times per second. The instrument also sends an emergency message to the Location Manager or ProRAE Guardian. Press [Y/+] to clear the alarm. The alarm stops and the display returns to the main reading screen. 3.6. Confidence LED You can use ProRAE Studio II to program the MicroRAE to continually provide an LED blink every 3 seconds so that you can tell without looking closely that the instrument is working.](https://usermanual.wiki/RAE-Systems/2601/User-Guide-2951316-Page-16.png)
![22 7. Turning The MicroRAE On And Off 7.1. Turning The MicroRAE On With the instrument turned off, press and hold the [MODE] key until the audible alarm stops, and then release. When starting up, the MicroRAE turns the backlight on and off, beeps once, blinks once, and vibrates once. A RAE Systems logo should appear first. During a normal startup, this is followed by a progression of screens that tell you the MicroRAE’s current settings. Then the MicroRAE’s main reading screen appears. It takes 45 seconds for some sensors to show a reading, so if any have not warmed up by the time the main screen is shown, you will see “- -” instead of a numerical value until the sensor provides data (if you turn a sensor off and on again, it also shows “- -” for up to 45 seconds). Then it displays instantaneous readings similar to the following screen (depending on the sensors installed) and is ready for use. Note: If the battery is completely empty, the MicroRAE shuts off. You should charge the before turning it on again. IMPORTANT! If a major error that prevents the MicroRAE from functioning is found during startup, the message “Contact Service” is shown on the display. The instrument should be shut off and serviced. 7.2. Turning The MicroRAE Off Press and hold [MODE]. A 5-second countdown to shutoff begins. You must hold your finger on the key for the entire shutoff process until the MicroRAE is powered off. Caution: The alarm is very loud. During startup, you can mute most of the sound by holding a finger over the alarm port. Do not put tape over the alarm port to permanently mute it.](https://usermanual.wiki/RAE-Systems/2601/User-Guide-2951316-Page-22.png)
![23 7.3. Testing Alarm Indicators Under normal-operation mode and non-alarm conditions, the buzzer, vibration alarm, LED, and backlight can be tested at any time by pressing [Y/+] once. IMPORTANT! If any alarm does not respond, check MicroRAE’s alarm settings to make sure all alarms are enabled (selected setting under Programming/Alarms/Alarm Settings should be “All Enabled”). If any alarms are enabled but not functional, the instrument should not be used. 7.4. Glance Mode Glance Mode allows you to get vital information without turning the MicroRAE on. You can check information such as the instrument’s model number, installed sensor types, etc., which may help when taking inventory of instruments and their sensors or when working with service or support personnel. Glance Mode can be enabled/disabled via ProRAE Studio II. 7.4.1 Enter Glance Mode Note: The instrument must be configured so that Glance Mode is turned on (the default mode is “On”). This can be done in ProRAE Studio II. With the MicroRAE turned off, press and hold [Y/+] to enter Glance Mode. The feature is latched, meaning that it runs even after you release the [Y/+] key. If you see the message “GLANCE DISABLED,” you must configure the instrument to use Glance Mode. If Glance Mode is enabled, the first screen is displayed. After releasing [Y/+], other screens release, other screens can be displayed by pressing the [Y/+] Key. In ProRAE Studio II, Glance Mode can be enabled or disabled by checking or unchecking the box labeled “Enable Glance Mode.”](https://usermanual.wiki/RAE-Systems/2601/User-Guide-2951316-Page-23.png)
![24 7.4.2 Screens Every screen displayed in sequence as configuration. Press [Y/+] to advance to the next screen. Press [MODE] to exit Glance Mode and turn the instrument off. The screens are shown in sequence. 7.4.3 Exit Glance Mode MicroRAE exits Glance Mode and turns off when you press the [MODE] key. In addition, if you do not press either key in 60 seconds, the MicroRAE automatically exits Glance Mode. 7.5. Comfort Beep A Comfort Beep is a single beep of the audible alarm at 60-second intervals that provides a reminder that the MicroRAE that it is functioning. It can be turned on or off. 7.6. Man Down Alarm The Man Down Alarm is a critical and potentially lifesaving safety feature of every MicroRAE. The Man Down Alarm is based on the premise that if the instrument is motionless when it is not supposed to be, something wrong may be happening to its user. If that is the case, the MicroRAE not only goes into alarm locally on the instrument, but also remotely, over a wireless network, to notify people in the vicinity, as well as remote safety officers at a command center, that a person is down, so that help can be dispatched quickly. Note: Remote notification requires wireless connection to a network. Whenever the Man Down feature is on, the main screen displays a Man Down icon along the top to indicate it is active: IMPORTANT! When gas alarm conditions exist at the same time as the Man Down alarm is activated, the pre-alarm stage is skipped, and the instrument goes straight into Super Alarm (gas and Man Down) with four beeps/flashes per second. When the Man Down feature is on and there is no gas alarm, the MicroRAE senses that it is motionless for the amount of time set in the “Motionless Time” parameter via ProRAE Studio II. If the instrument is not moved during that time, then a pre-alarm is activated to alert the user, and shows the “OK?” screen. Pressing [Y/+] clears the alarm and returns the MicroRAE to its normal operation. Pressing [MODE] sets it into Man Down Alarm (and if wireless connectivity is enabled, a Man Down message is sent in real time to remote observers). If neither key is pressed, then after the countdown, it goes into Man Down Alarm (again sending a message to remote observers if wirelessly enabled). Settings are available for: Off/On Window (time the instrument is motionless before initiating a pre-alarm, in seconds) Sensitivity (set to low, medium, or high to compensate for ambient vibration or motion) Warning Time (countdown, in seconds, from pre-alarm to Man Down alarm)](https://usermanual.wiki/RAE-Systems/2601/User-Guide-2951316-Page-24.png)
![25 When the Man Down alarm is activated, the buzzer sounds and LEDs flash continuously, and a countdown begins. If the MicroRAE’s user presses [Y/+] for “Yes” in response to the “OK?” question on the screen before the countdown reaches zero, the Man Down alarm stops and the main reading screen is displayed. If the person does not press [Y/+] for “Yes” in response to the “OK?” question on the screen before the countdown reaches zero, the Man Down alarm is sounded and LEDs flash continuously. If the person presses [MODE] during the countdown, answering the “OK?” question by pressing [MODE] for “No,” the Man Down alarm starts. If wireless connectivity is enabled, and the QRAE 3 is connected to a network, a Man Down message is also sent to remote observers. 7.7. Calibration Status If any sensor requires calibration, then “Calibration Overdue” icon is shown by the sensor name in the display: Calibration is required if: The sensor module has been replaced with one whose calibration is overdue. The defined period of time between calibrations has been exceeded, according to the policy set for the instrument. If you have changed the calibration gas type without recalibrating the instrument. The sensor has failed a previous calibration.](https://usermanual.wiki/RAE-Systems/2601/User-Guide-2951316-Page-25.png)
![27 8. Modes Of Operation The MicroRAE has two user modes, selectable through ProRAE Studio II. 8.1. Basic User Mode In Basic User Mode, some restrictions are applied, including password protection that guards against entering Programming Mode by unauthorized personnel. 8.2. Advanced User Mode In Advanced User Mode, there are no access restrictions (you do not need a password), and the MicroRAE provides the indications and data you need most for typical monitoring applications. 9. Programming The menu in Programming Mode is to adjust many of the MicroRAE’s settings, calibrate sensors, and initiate communication with a computer. It has the following submenus: Calibration Sensor On/Off Clear Datalog Monitor Setup Set Radio (Wireless) Note: Some settings are only visible and can only be changed in ProRAE Studio II. This requires connecting the instrument to a computer running ProRAE Studio II and having administrative privileges.

Install the calibration adapter on the MicroRAE by setting it on over the sensors and turning the knob until it is snug against the surface of the instrument. 3. Turn on the gas to initiate flow. 4. Connect the calibration adapter to the calibration gas. 5. Press Start ([Y/+] key) to start the bump test, or press [MODE] to quit. While the bump test is being performed, the readings for each sensor are shown. Once the bump test completes, pass/fail test results and readings are shown for each sensor. Important! If one or more sensors fails a bump test, be sure to calibrate those sensors.](https://usermanual.wiki/RAE-Systems/2601/User-Guide-2951316-Page-41.png)
![42 6. The bump test is now complete. Press [MODE] to exit to the next bump or calibration type in the Calibration menu. (Press [MODE] several times until you see “Exit,” and then press [Y/+] to continue through other menu options. If all the alarms and all sensors have passed and no sensor is due for a calibration, the instrument is now ready for use. 11.2. Zero Calibration This operation sets the zero point of the sensor calibration curve for clean air. It should be performed before other calibrations. Note: If you use a zero air cylinder, you must use the MicroRAE Calibration Adapter. Using a calibration adapter is not necessary for calibration in fresh air. 11.2.1. Zero Calibration This procedure determines zero points of most sensors. The MicroRAE should be zero-calibrated in clean air with 20.9% oxygen or with a cylinder of clean zero air. At the Calibration menu, select “Fresh Air” by pressing [Y/+] once to enter fresh air calibration. After a timer countdown, the zero calibration is done. The LCD displays the sensor names and tells you whether each calibration passed or failed, followed by the sensor readings. Note: You can abort the calibration at any time during the countdown by pressing [MODE]. 11.2.2. Single-Sensor Zero Calibration Select the sensor and then start the calibration by pressing [Y/+]. You can abort the procedure anytime by pressing [MODE].](https://usermanual.wiki/RAE-Systems/2601/User-Guide-2951316-Page-42.png)
![43 11.3. Span Calibration This procedure determines the second point of the sensor calibration curve for the sensor. Note: When a manual calibration is performed, the readings shown are in the equivalent units of the calibration gas, and not the measurement gas. When performing a Span calibration, the Calibration Adapter must be used for supplying calibration gas to all sensors at one time: 1. Align the Calibration Adapter’s main body with the indented area around the MicroRAE’s gas inlets. 2. Turn the knob clockwise to secure the Calibration Adapter to the instrument. 3. Connect the hose to the Calibration Adapter and to its gas source. 4. Make sure the Calibration Adapter is securely attached before starting the flow of calibration gas. (The Calibration Adapter has small grooves on its underside to allow gas to escape after passing over the sensors.) 11.3.3 Multi-Sensor Span Calibration This lets you perform a span calibration on multiple sensors simultaneously. It requires using the appropriate span gas and that the concentration labeled on the gas cylinder matches the concentration programmed in the MicroRAE. 1. Start the flow of calibration gas. 2. Attach the calibration adapter and gas to the MicroRAE. 3. Press [Y/+] to begin calibration. A countdown screen is shown. You can abort the calibration at any time during the countdown by pressing [MODE]. If the calibration reaches its conclusion, it shows the sensor names and tells you whether the calibration passed or failed, followed by the sensor readings. 11.3.4. Single-Sensor Span Calibration To perform span calibration of an individual sensor, follow these steps: 1. At the Calibration Menu, select “Single Sensor Span.” 2. Select a sensor from the list. 3. Start the flow of calibration gas. 4. Connect the calibration adapter and connect it to a source of calibration gas. 5. Verify that the displayed calibration value meets the concentration label on the gas cylinder.](https://usermanual.wiki/RAE-Systems/2601/User-Guide-2951316-Page-43.png)
![44 6. Press [Y/+] to start calibrating. You can abort the calibration at any time during the countdown by pressing [MODE]. After a timer countdown, the span calibration is done. The LCD will display whether the calibration was successful and the reading for that calibration gas. Note: If the sensor calibration fails, try again. If calibration fails again, turn off the power and then replace the sensor.

![45 12. Datalog Transfer, Monitor Configuration, and Firmware Upgrades Via Computer Note: Basic functionality can be adjusted via the MicroRAE’s interface, but more extensive functionality and parameters can be adjusted using ProRAE Studio II software. Datalogs can be downloaded from the MicroRAE to a computer, and firmware updates can be uploaded to the MicroRAE via the USB port on the Travel Charger. Use the included Mini B USB (5-pin)-to-USB cable to connect the Travel Charger to a computer running ProRAE Studio II (version 1.10.0 or higher). 12.1. Downloading Datalogs And Performing PC-Based Instrument Configuration and Firmware Upgrades The MicroRAE communicates with a PC running ProRAE Studio II Instrument Configuration and Data Management software to download datalogs, configure the instrument, or upload new firmware. The MicroRAE must be connected to a PC through the supplied Travel Charger and must be in the PC communications mode. 1. Use the supplied PC Communications Cable (USB to mini-USB cable) to connect the Travel Charger to a PC. 2. Turn on the MicroRAE. Make sure it is running (with the main measurement screen showing). 3. Activate the PC communications mode on the MicroRAE by pressing [MODE] repeatedly, starting from the main measurement screen until you reach the “Comm Mode” screen. 4. Press [Y/+]. Measurement and datalogging stop, and the instrument is now ready to communicate with the PC. The display now says “Ready To PC”. 5. Start up the ProRAE Studio II software, enter a password, and detect the instrument following the directions provided in the ProRAE Studio II User’s Guide. 6.
