1. Connect the black test lead to the "COM" jack and the red test lead to
the input jack.
2. Set the selection button to the desired "
3. Connect the test leads across the source under measurement.
4. Read the voltage value on the LCD display.
10.3 CURRENT MEASUREMENT
Do not measure circuits that may contain voltages > 600 V AC or DC
Use extreme caution when measuring voltages higher than 60 VDC
or 30 VAC rms.
1. Set the selection button to the desired "A" position
2. Press the RAN function button to select the desired range.
3. Open the clamp by pressing the clamp trigger and insert the cable
(one cable only) to be measured into the jaw.
4. Close the clamp and read the current value on the LCD display.
Notes
 Before measurement, disconnect the test leads from the meter.
 An over-range is indicated by OL.
10.4 RESISTANCE MEASUREMENT
Do not conduct resistance measurements on live circuits. Make sure
all capacitors in the circuit are depleted.
1. Connect the black test lead to the "COM" jack and the red test lead to
the input jack.
2. Set the selection button to the desired "
3. Press the SEL function button to select the "" measurement.
4. Connect the test leads across the source under measurement.
5. Read the voltage value on the LCD display.
Notes
 If the resistance being measured is connected to a circuit, turn off the
power and discharge all capacitors before applying the test probes.
 An over-range is indicated by OL.
10.5 DIODE MEASUREMENT
Do not conduct diode measurements on live circuits. Make sure all
capacitors in the circuit are depleted.
