3)
Select proper range according to the input AC voltage.
Range
200mV, 2V, 20V, 200V, 750V
Input protection
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 signal cycle 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.
2.3.8 Continuity Test
Continuity test uses 2-wire mode to measure the resistance of circuit at a current of 1mA in order to check
the integrity of the circuit.
When the measured resistance value in the short-circuit circuit is lower than the set short-circuit
resistance, the circuit is connected, and the beeper continuously beeps. The connecting and
measurement methods are shown below:
1)
Press
button to enter interface of continuity test as Figure 2-23.
Figure 2-23 interface of continuity test
Connect the test leads to the measured circuit as Figure 2-24, connect the red test lead to terminal Input-
HI, and the black one to terminal Input-LO.
