5. Use caution when working near voltages above 30 VAC rms, 42 VAC peak, or 60 VDC. Voltages this high present a risk of electric shock. 6. Disconnect the circuit’s power before connecting the meter in series, when measuring current. 7. Connect the common (COM) test lead first and disconnect it last. 8. Hold the probes with fingers behind guards. 9. Test cable voltages with care. Only use one hand when securing the tester around the cable to reduce risk of injury in case of electric shock. 10.

CAUTION 1. Avoid damaging meter. Use only as specified in this manual. 2. Prior to testing capacitors, resistance, diodes, or continuity; disconnect all power to the circuit and discharge all high-voltage capacitors. 3. Performance of this meter may vary depending on battery condition. 4. Use the proper settings, terminals, techniques, and range for the tests performed. Always start with the range stated in the instructions. 5.

Peak Hold Function 1. The Peak Hold function is used to keep the display reading the highest measurement after the measurement is finished. Press and release the peak hold button to keep displaying the current measurement. 2. Press and release the Peak Hold button again to resume normal operation. 3. Make sure the Peak Hold button is not engaged before taking a measurement. AC Current Measurements 1. Turn the Range Selector Switch to the A 1000 position.

Diode Measurement Test the voltage drop in diodes. 1. Turn the Range Selector Switch to the Diode ( ) position. 2. Plug the red Test Lead into the V 1K Jack. Plug the black Test Lead into the Com Jack. Switch the Multimeter ON. 3. Connect the red probe to the anode of the diode and the black to the cathode. 4. The approximate forward voltage drop of the diode will be displayed in mV. If the connection is reversed only “1” will be shown.
