233 Users Manual 16 How to Make Measurements The sections that follow tell how to make measurements with the Meter. To connect the test leads to the circuit or device, connect the common (COM) test lead first. To remove the test leads, remove the common test lead last. AC and DC Voltage Measurements The voltage ranges are 600.0 mV, 6.000 V, 60.00 V, 600.0 V, and 1000 V. To set the 600.0 mV dc or ac range, turn the function switch to . Millivolts ac is set first. Push  to switch to millivolts dc. Refer to Figure 1 to measure ac or dc voltage. For voltage measurements, the Meter puts approximately 10 MΩ (10,000,000 Ω) in parallel with the circuit. This load can cause measurement errors in high-impedance circuits. In most cases, the error is negligible (0.1 % or less) if the circuit impedance is 10 kΩ (10,000 Ω) or less. Switch BoxAC Voltage+DC VoltageV gcc102.eps Figure 1. AC and DC Voltage Measurements
True-rms Remote Display Digital Multimeter How to Make Measurements 17 Resistance Measurements WCaution To prevent possible damage to the Meter or to the equipment under test, disconnect power and discharge all high-voltage capacitors before resistance measurements. The Meter sends a small current through the circuit for resistance measurements. Because this current flows through all possible paths between the probes, the resistance measured is the total resistance of all paths between the probes. The resistance ranges are 600.0 Ω, 6.000 kΩ, 60.00 kΩ, 600.0 kΩ, 6.000 MΩ, and 40.00 MΩ. Set the Meter as shown in Figure 2 to measure resistance. Below are some hints for resistance measurements: • The measured value of a resistor in a circuit is frequently different from the specified resistor value. • The test leads can add 0.1 Ω to 0.2 Ω of error to resistance measurements. To measure test lead resistance, touch the probe points together and read the resistance. • The resistance function uses sufficient voltage to forward-bias silicon diode or transistor junctions, and cause current to flow. If you think current flows through the junction, push  to apply a lower current in the next higher range. If the value is higher, use the higher value. Refer to the Input Parameters table in the specifications section for typical short-circuit currents.

True-rms Remote Display Digital Multimeter How to Make Measurements 19 Temperature Measurements The Meter measures the temperature of a type-K thermocouple (included). Choose between degrees Celsius (°C) or degrees Fahrenheit (°F) by pushing C. W Caution To prevent possible damage to the Meter or other equipment, use a thermocouple rated for the temperatures to be measured. The Meter is rated for -40.0 °C to +400.0 °C and -40.0 °F to 752 °F, but the included type-K thermocouple is rated to 260 °C. The temperature ranges are -40.0 °C to +400 °C and -40.0 °F to 752 °F. All other temperatures show  on the display. When there is no thermocouple connected, the display shows . To measure temperature: 1. Connect a type-K thermocouple to the COM and  terminals of the Meter. 2. Turn the function switch to . 3. Push C to choose Celsius or Fahrenheit. Continuity Tests WCaution To prevent possible damage to the Meter or the equipment under test, disconnect power and discharge all high-voltage capacitors before a continuity test. The continuity test uses a beeper that sounds when a closed circuit is sensed. The beeper lets you do continuity tests without the necessity to look at the display. To do a continuity test, set up the Meter as shown in Figure 3.
233 Users Manual 20 For in-circuit tests, turn circuit power off.OFF(open)ON(closed)Activates continuity beeper gcc103.eps Figure 3. Continuity Tests
True-rms Remote Display Digital Multimeter How to Make Measurements 21 Diode Tests WCaution To prevent possible damage to the Meter or to the equipment under test, disconnect power and discharge all high-voltage capacitors before a diode test. Do a diode test on diodes, transistors, silicon controlled rectifiers (SCRs), and other semiconductor devices. This function sends a current through the semiconductor junction and then measures the voltage drop across the junction. A good silicon junction drops between 0.5 V and 0.8 V. To do a diode test on a diode out of a circuit, set up the Meter as shown in Figure 4. For forward-bias measurements on a semiconductor component, put the red test lead on the positive terminal of the component and put the black test lead on the negative terminal of the component. In a circuit, a good diode has a forward-bias measurement of 0.5 V to 0.8 V. A reverse-bias measurement includes the resistance of other pathways between the probes. A short beep sounds if the diode is good (<0.85 V). A continuous beep sounds if the measurement is ≤0.100 V or short circuit. The display shows “” if the diode is open.

True-rms Remote Display Digital Multimeter How to Make Measurements 23 Capacitance Measurements WCaution To prevent possible damage to the Meter or to the equipment under test, disconnect power and discharge all high-voltage capacitors before capacitance measurements. Use the dc voltage function to make sure that the capacitor is discharged. Capacitance ranges are 1000 nF, 10.00 μF, 100.0 μF, and 9999 μF. To measure capacitance, set up the Meter as shown in Figure 5. +++++++++SelectCapacitance gcc104.eps Figure 5. Capacitance Measurements
233 Users Manual 24 AC and DC Current Measurements XWWarning To prevent possible electrical shock or personal injury, do not make an in-circuit current measurement where the open-circuit potential to earth is >1000 V. Meter damage or injury can occur if the fuse blows during such a measurement. WCaution To prevent possible damage to the Meter or to the equipment under test: • Do a fuse test before current measurements. • Use the correct terminals, function, and range for all measurements. • Do not put the probes across (in parallel with) a circuit or component when the test leads are connected to the current terminals. To measure current, you must break the test circuit, then put the Meter in series with the circuit. The current ranges are 6.000 A, and 10.00 A. AC current is shown as an rms value. To measure current (see Figure 6): 1. Remove power from the circuit. Discharge all high-voltage capacitors. 2. Put the black test lead into the COM terminal. Put the red test lead into the A terminal. 3. Set the function switch to  for ac current or  for dc current.

233 Users Manual 26 Frequency Measurements A frequency measurement is a count of the number of times an ac voltage or current signal crosses a threshold point each second. To make a frequency measurement: 1. Set the function switch to  for voltage or  for current. 2. Connect the Meter to the signal source. 3. Push . The Meter autoranges to one of four frequency ranges: 99.99 Hz, 999.9 Hz, 9.999 kHz, and 50 kHz. Below are some hints for frequency measurements: • If a measurement shows as 0 Hz or is not stable, the input signal can be below or near the trigger level. A lower range increases the sensitivity of the Meter and can usually repair these problems. • An input signal with distortion can cause a frequency measurement to be higher than usual. The distortion can cause multiple triggerings of the frequency counter. A higher voltage range decreases the input sensitivity and can correct this problem. In general, the lowest frequency is the correct one. Remote Operation The Meter uses low-power 802.15.4 wireless technology to allow the display module to operate in a different location than the Meter base. Although there is control of some Meter functions (Hold, MIN MAX AVG, Range, and Backlight), complete remote control of the Meter is not available through the display module. The wireless radio does not interfere with meter measurements. Usually, the radio is off when the display module is docked on the Meter base. It is possible for the radio to be on when the display module is docked and the function switch is set to OFF. To make sure that the radio is off, remove the batteries from the Meter base and display module. The display module is synchronized with a Meter base when it is docked on the Meter base and turned on. Different display modules can be synchronized with a Meter base but, only one display module can be synchronized to a Meter base at the same time.
True-rms Remote Display Digital Multimeter Remote Operation 27 Remove the Display Module To remove the display module (see Figure 7): 1. Push in on the latches on the sides of the display module. 2. Pull the display module off of the top end of the Meter base. The Meter base and display module can be a maximum of 10 Meters (30 feet) from each other before the radio connection is broken. This distance can change if obstacles are between the Meter base and the display module. There is a radio connection between the display module and Meter base when  shows in the display. When the display module and Meter base lose the radio connection, the display shows dashes and  blinks. Possible causes for this loss are the distance is too far for the environment or the batteries in the Meter base are dead. To reconnect, decrease the distance between the display module and Meter base. 21 gcc114.eps Figure 7. Display Module Separation
233 Users Manual 28 If the radios in the Meter base and display module do not connect,   flashes in the display. Dock the display module with the Meter base and turn the Meter off and then on. When the Meter is turned on, the red high-voltage LED on the Meter base flashes. If not, replace the Meter base batteries. For maximum battery life, dock the display module to the Meter base when the Meter is off. The display module has a built-in magnet to attach to metal surfaces. Dock the Display Module with the Meter base To dock the display with the Meter base as shown in Figure 8: 1. Set the display on the top 10 millimeters of the Meter base with the battery compartment of the display in the channel in the top of the Meter base. 2. Push the display nearer the Meter base until the display latches catch. 21 gcc115.eps Figure 8. Dock Display Module with Meter Base
True-rms Remote Display Digital Multimeter Maintenance 29 Maintenance XWWarning To prevent a possible electrical shock or personal injury, have an approved technician repair the Meter. General Maintenance Clean the case with a damp cloth and weak detergent. Do not use a solvent or cleaners with abrasives. Dirt or moisture in the terminals can cause incorrect measurements. To clean the terminals: 1. Turn the Meter off and remove all test leads. 2. Shake out dirt that can possibly be in the terminals. 3. Soak a clean swab with weak detergent and water. Move the swab around in each terminal. Dry each terminal with canned air to push the water and detergent out of the terminals. XWWarning To prevent electrical shock or personal injury, remove the test leads and all input signals before you replace the batteries or fuses.
