АМM-1130
PEAK-H: It has calibration for peak mode, peak max value and peak min value mode.
Delay HOLD: When releasing the HOLD key after pressing it for two seconds, the meter will delay for 6 seconds, then
enter HOLD mode. By this way you could better operation than other way for hold on the metrical data
DCV Measurement
The measurement is shown in Figure 3-1,the range of voltage is of DC 0.23V～1000V and the methods are as follows:
1.
Switch and set the rotary-table switch to the position
Insert the red testing line into the VΩ℃ end and the black testing line into the COM end.
2.
3.
When performing DCV measurement, connect the red probe to the positive polarity of the measured voltage and the black
probe to the negative polarity of the measured voltage.
4.
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 the both red and black probes from the measured circuit
immediately.
5.
When performing DCV measurement, by pressing the RANGE key it is possible to select range manually. If OL
displaying during manual range measurement, it is necessary to select a larger range. If OL displaying under the maximum
range, it indicates the voltage exceeding 1000V and it is necessary to remove the both red and black probes from the
measured circuit immediately.
Notes: 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.
