Make sure the Low Battery Display is not on,
otherwise false readings may be provided.
Pay extra attention to the symbol which is located

A. DC Voltage Measurement (see 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 or 750V rms although
readings may be obtained.
Take extra attention when measuring high voltages
to avoid electric shock.
To measure DC voltage, connect the Meter as follows:
1. Insert the red test lead into the VΩ input terminal and
the black test lead into the COM input terminal.
2. Set the rotary switch to an appropriate measurement
position in V range.
3. Connect the test leads across with the object being
measured.
The measured value shows on the display.
