10. Operation

10.1 VOLTAGE 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.
Always place your fingers behind the protective edges of the test
probes while measuring!
1. Connect the black test lead to the "COM" jack and the red test lead to
the "V
2. Set the selection switch to the desired "
3. Press the selection button to choose the AC or DC voltage
measurement.
4. Connect the test leads across the source under measurement.
5. Read the voltage value on the LCD display.

10.2 AC 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 switch to the desired "20A" or "200/500A" position.
2. Open the clamp by pressing the clamp trigger and insert the cable
(one cable only) to be measured into the jaw.
3. Close the clamp and read the current value on the LCD display.
Notes
 Before measurement, disconnect the test leads from the meter.
 In some occasions that the reading is hard to read, press the D-hold
button and read the result later.

10.3 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 "V
2. Set the selection switch to the desired "
