( figure 3)
Warning
To avoid harms to you or damages to the Meter from
electric shock, please do not attempt to measure
voltages higher than 1000V DC/750V AC although
readings may be obtained.
The DC voltage ranges are: 200.0mV, 2.000V, 20.00V,
200.0V and 1000V.
To measure DC voltage, 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 an appropriate measurement
position in V .
3. Connect the test leads across with the object being
measured.
The measured value shows on the display.
Note
l
If the value of voltage to be measured is unknown,
use the maximum measurement position (1000V)
and reduce the range step by step until a satisfactory
reading is obtained.
