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 “
V
Ω
” 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.

To measure resistance, connect the meter as follows:
①
Insert the red test lead into the ”
V
Ω
” 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 0.1
Ω
to 0.2
Ω
of error to resistance measurement.
To obtain precision reading in low-resistance measurement, that is the
range of 200.0
Ω
, short the input terminal before measuring. In this time,
the contact resistance displayed on the LCD. You can subtract the
