5. Measurement operation
5-1 DC & AC voltage measurement
Warning
To avoid harms to you or damage to the meter from electric
shock. Please do not attempt to measure voltage higher than
DC/AC 1000V although readings may be obtained.
The DC voltage range are 200.0mV, 2.000V, 20.00V , 200.0V and 600V and
then. The AC voltage ranges are 2.000V, 20.00V, 200.0V and 600V.
To measure DC or AC voltage:
1. Insert the red test lead into the “VΩ” input terminal and the black test
lead into the COM terminal.
2. Set the rotary switch to DC or AC range.
3. Connect the test lead across with the object under testing.
The measured value will be show on the LCD display.
Note:
When DC or AC voltage measurement has been completed,
disconnect the connection
between the testing lead and the circuit under testing.

5-2. Resistance measurement
The resistance range are: 200.0Ω, 2.000KΩ,20.00KΩ, 200.0KΩ ,
2.000MΩ.
20.00MΩ.
To measure resistance, connect the meter as follows:
1. Insert the red test lead into the ”VΩ” terminal and the black test lead into
the COM terminal.
2. Set the rotary switch to proper resistance range..
3. Connect the test lead across with the object under testing.
The measured value will be show on the LCD display.
Note:
The test lead can add 0.1Ω to 0.2 Ω of error to resistance
measurement. To obtain precision reading in low-resistance
measurement, that is the range of 200.0Ω, short the input terminal
before measuring. In this time, the contact resistance displayed on the
LCD. You can subtract the contact resistance value from the measured
value.
For high-resistance measurement (>10MΩ), it is normal taking
several second to obtain stable reading.
The LCD display “OL” indicating open-circuit for the tested resistor
or the resistor value is higher than the maximum range of the meter.
