To Measure AC Voltage
In view of AC voltage measurement function, the following part demonstrated how
to link the measurement connection and how to choose measurement functions. The
following practice will gradually guide you to be familiar with the AC Voltage
measurement technique.
Figure 1-10
AC Voltage measurement data interface
Table 1-2 DC Voltage measurement characteristics
Five Range 200mV, 2V, 20V, 200V, 750V
Max Resolution 100nV
Import Protection 750VRMS on all ranges (HI Terminal)
Configurable
Parameters
Range, DC impedance, Null value
Basic measurement:
1. Connect test leads as Figure 1-11 shown. Red test lead connects the HI Terminal,
Black test lead connects the LO Terminal.
2. Press to select the AC Voltage measurement function.
3. According to the voltage measuring scope, choose the correct range.
4. Setup the DC impedance.
Press Æ Filter , to setup the AC Filter Bandwidth. Default value of the AC
Filter Bandwidth will be 10MΩ, this parameter had been setup, and users may carry
on the AC Voltage measurement directly without modification.
5. Set the Null value
Null computing will be an option operation, could be setup in accordance with
user demand. If user does not implement Null computing, this parameter is not
required, direct implementation of the next step.
