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:
■
Insert the red test lead into the "VΩ" input terminal and the black test lead into the COM
terminal.
■
Set the rotary switch to DC or AC range.
■
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:
■ Insert the red test lead into the "VΩ" terminal and the black test lead into the COM
terminal.
■ Set the rotary switch to proper resistance range.
■ 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 0.2Ω 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.
