Measurement Operation (3)
C. DC Millivolt Measurement (see figure 5)
Warning
To avoid harms to you or damages to the Meter from
electric shock, please do not attempt to measure
voltages higher than 1000V / 750V rms although
readings may be obtained.
The DC Millivolt ranges are: 80.00mV and 800.0mV.
These ranges have more than 4000M . To measure
DC Millivolt, connect the Meter as follows:
1. Insert the red test lead into the
V Hz terminal
and the black test lead into the COM terminal.
2. Set the rotary switch to mV
.
3. Connect the test leads across with the object being
measured.
The measured value shows on the display.
Note
l In each range, the Meter has an input impedance
of 10M . This loading effect can cause
measurement errors in high impedance circuits. If
the circuit impedance is less than or equal to 10k ,
the error is negligible (0.1% or less).
l When DC millivolt measurement has been completed,
disconnect the connection between the testing leads
and the circuit under test.
