Page 7 Maintenance Additional Multimeter Precautions General Operating Instructions AC Voltage Measurements Safety Measure AC conductors carrying up to 700 VAC, 45-450 Hz. 3. Carefully touch the exposed conductors with the tips of the probes to measure the voltage (not amperes). 4. Read measurement. If the voltage is less than 200 volts, set the Range Selector Switch to the lower range. 1. Turn the Range Selector Switch to 700 ACV setting. Start with the highest range if the voltage is unknown. 2. Plug the red lead into the V/Ω/Hz Jack. Plug the black lead into the COM 5. Jack. Switch the Multimeter ON. When testing is complete, remove Test Leads and store with multimeter. DC Voltage Measurements Setup Measure DC conductors carrying up to 1000 VDC. 1. 2. Follow the directions above under “AC Voltage Measurements”, only use the DC settings instead. 3. Carefully touch the exposed conductors with the tips of the probes to measure the amperage. Turn the Range Selector Switch to 1000 DCV setting. AC Current Measurements Measure AC conductors carrying up to 20 amperes. Operation 1. Turn the Range Selector Switch to the 20A~ position. Start with the highest range if the amperage is unknown. 2. Plug the red lead into the 20A Jack. (For current under 20A, plug the red lead into the mA Jack.) Plug the black lead into the COM Jack. Switch the Multimeter ON. Note: Amperage is always tested in series with the circuit under test. 4. Read measurement. If the reading is less than 0.2 amps, switch the red lead to the VΩmA Jack and set the Range Selector Switch to the 200 mA setting. 5. When testing is complete, remove Test Leads and store with multimeter. 2. Follow the directions above under “AC Current Measurements”, only use the DC settings instead. DC Current Measurements Measure DC conductors carrying up to 20 amperes. Maintenance 1. Page 8 Turn the Range Selector Switch to the 20A position. Start with the highest range if the amperage is unknown. For technical questions, please call 1-888-866-5797. Item 37772 61593 WARNING! Do not measure resistance on circuit with voltage running through it. Notice: When measuring Ohms, start with the lowest range if the resistance is unknown. 1. Turn the Range Selector Switch to the 200Ω position. 2. Plug the red Test Lead into the V/Ω/ Hz Jack. Plug the black Test Lead into the COM Jack. Switch the Multimeter ON. Short the Test Leads together. The meter should read “0” Ohms. 3. Touch the exposed conductors with the tips of the Test Leads. Read measurement. If the reading is “1”, set the Range Selector Switch to the next higher Ohm (Ω) position. 5. When measuring resistance above 1 MΩ, the meter may take a few seconds to give a stable reading. This is normal for high resistance measurements. 6. At the 20MΩ range, the display reading will be around 0.1 counts over the actual measurement. These counts should be subtracted from the resulting reading. For example, when measuring 10 MΩ resistance, the display will read 10.1, but the correct measurement should be 10.1-0.1=10.0MΩ 7. Remove and store Test Leads. 2. Plug capacitor into the capacitance testing socket (Cx). Switch the Multimeter ON. 3. Read measurement. If the reading is less than 20μF, set the Range Selector Switch to a lower range. Setup Measure circuit resistance up to 20M Ohms. 4. Safety Resistance Measurements Measure capacitance up to 20μF. 1. Turn the Range Selector Switch to the 20μF position. Start with the highest range if the capacitance is unknown. WARNING! Fully discharge capacitor before measuring. Operation Capacitance Measurements WARNING! Avoid electric shock. Remove capacitor before switching between testing modes. 1. Turn the Range Selector Switch to the 20kHz position. Note: Reading is possible at input voltages above 10Vrms, but the accuracy is not guaranteed. 2. Plug the red Test Lead into the V/Ω/Hz Jack. Plug the black Test Lead into the COM Jack. Switch the Multimeter ON. 3. Measure frequency up to 20kHz. Item 37772 61593 Note: In noisy enviroments, use a shield cable to measure smaller signals. Remove and store Test Leads.
