3)
Select proper range according to the input AC voltage.
Range
200mV, 2V, 20V, 200V, 750V
Input protection
DC 1000V or AC 750Vrms for all ranges (terminal HI)
Configurable parameters
Voltage range, relative operation set value
4)
Relative value setting
Turn the relative operation on, the displayed value is actual measured value minus the set relative value.
About relative value setting, please refer to 2.10 Mathematical Functions.
5)
Measured value reading
The reading speed of frequency measurement depends on the frequency of measured signal.
6)
History data review
User can check the history data by number, bar chart, trend chart, and histogram.
2.3.7 Signal Cycle Measurement
Frequency value can be read by turning on the dual display function in AC voltage measurement. Besides
that, the same frequency value can be read in frequency measurement. The connecting and
measurement methods are shown below:
1)
Press
button and then press
button to enter interface of signal cycle measurement as
Figure 2-21.
Figure 2-21 Interface of signal cycle measurement
2)
Connect the test leads to the measured signal as figure 2-22, connect the red test lead to the terminal
Input-HI, and the black one to terminal Input-LO.
