Parameters
Range, Null value
Basic measurement:
1. Connect test leads as Figure 1-17 shown. Red test lead connects the HI Terminal,
Black test lead connects the LO Terminal.
2. Press to select the DC Current measurement function.
3. According to the current 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 “Mid”(Middle), this parameter had been setup, and the users
may carry on the AC Voltage measurement directly without modification.
7. Set the Null setting value
Null computing will be an option operation, could be setup in accordance with
