Warning
To avoid harms to you or damages to the Meter
from electric shock, please do not attempt to
measure voltages higher than 400mV, although
readings may be obtained.
To measure DC Millivoltage Measurement, set up the
Meter as Figure 3-3 and do the following:
1. Insert the red test lead into the V terminal and the
black test lead into the COM terminal.
2. Set the rotary switch to . Press the SELECT
button cycles among , frequency and duty
cycle.
3. Connect the test leads across with the object being
measured.
The measured value shows on the display.
It displays the RMS.
When measuring DC Millivoltage, the Meter acts
around a 2.5GΩ input impedance in parallel with
the circuit.
Special care should be taken when measuring high
voltage.
When voltage measurement has been completed,
disconnect the connection between the testing leads
and the circuit under test and remove testing leads
away from the input terminals of the Meter.
