OPERATING MANUAL
RESISTANCE MEASUREMENT
WARNING
!
• To avoid damaging the meter or to the device under test, disconnect
circuit power and discharge all the high-voltage capacitors before
measuring resistance.
• To avoid electric shock, do not input higher than DC 60V or AC 30V
voltages.
1. Switch the function selector to
Ω
position (range: 600Ω/6kΩ/60kΩ/600MΩ/60MΩ), make
sure the circuit power is turned off.
2. Connect the common test lead to COM terminal then insert the red test lead to

C
terminal.
3. Connect the leads to the correct test points in the circuit to measure voltage.
NOTE:
•
If the measured resistor is open or the resistance exceeds the maximum range, the “OL”
symbol will be displayed on the screen.
•
When measuring low resistance, the test leads will produce 0.1Ω-0.3Ω measurement error. To
obtain accurate measurement, short-circuit the test leads and use the REL function.
•
If the resistance is greater than 0.5Ω when the test leads are shorted, please check if the test
leads are loose or damaged.
•
When measuring high resistance at 60MΩ range, it takes a few seconds to stabilise the
readings.
•
The internal 600mA and 20A fuses can be checked by the 6MΩ measurement function.
Please refer to Picture 5b for more details: Insert the red probe to the 630mA or 20A input
terminal to measure the resistance. If both fuses are blown, the “OL” symbol will appear on
the screen.
