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 shown 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 , 2.000M

Ω.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 0.2Ω 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
