10. Operation

10.1 VOLTAGE MEASUREMENT
Do not measure circuits that may contain voltages > 500 VDC or
> 500 VAC
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. Switch on the device.
2. Connect the red test lead to the "V" jack and the black lead to the
"COM" jack.
3. Press "
measurement mode.
4. Connect the test leads to the source being measured.
5. Read the voltage value and the polarity of the red test lead on the LCD
display.
10.2 RESISTANCE MEASUREMENT
Do not conduct resistance measurements on live circuits. Make sure
all capacitors in the circuit are depleted.
1. Switch on the device.
2. Connect the red test lead to the "V" jack and the black lead to the
"COM" jack.
3. Press "Ω
4. Connect the test leads to the resistor to be measured and read the
LCD display.
10.3 DIODE AND CONTINUITY TEST
Do not conduct diode or continuity measurements on live circuits.
Make sure all capacitors in the circuit are depleted.
1. Switch on the device.
2. Connect the red test lead to the "V" jack and the black lead to the
"COM" jack.
3. Press "Ω
