DC mV/AC mV Measurement
The testing chart is shown in the Figure 3-3. The voltage measurement range is of 10
μV
~
220mV and the measurement
methods are as follows:
1.
Turn on the power switch and set the rotary switch to the position .
2.
Insert the red testing line into the
VΩHz
end and the black testing line into the
COM
end.
3.
Press the
FUNC.
key to select
DCmV
measurement modes.
4.
When performing
DCmV
or
AcmV
measurement, connect the red probe to the positive polarity of the measured
voltage and the black probe to its negative polarity.
5.
Read the measured value from the display screen. If OL displaying on the meter, it indicates the measured voltage
exceeding the range of the meter and it is necessary to remove both the red and black probes from the measured circuit
immediately.
6.
In this mode, it is null to press the
RANGE
key
Notes:
a)In case of probe hanging in the air, the voltage inducted by the testing line may cause unstable readings on the display screen,
but that will not affect the accuracy of measurement.
b)The meter is a true rms responding meter. When the input leads are shorted together in the ac functions, the Meter may display
a residual reading between 1 and 30 counts. It will not attect stated accuracy, but if using REL to offset this reading may produce a
much larger constant error in later measurements.
