To Measure AC Voltage
The following shows the system connections and selection of measurement functions.
This practice provides a guide to get familiar with the AC Voltage measurement
technique. (The AC functions only support 5½ digits measurement.)
Figure 1- 9 AC Voltage Measurement Data Interface
Table1- 2 AC Voltage Measurement Characteristics
Five Ranges 200mV, 2V, 20V, 200V, 750V
Max Resolution 100nV
Input Protection 750VRMS on all ranges (HI Termi nal)
Configurable
Parameters
Range, DC impedance, Null value
Steps:
1. Connect test leads as shown in
Figure 1- 10; red test lead to the HI Terminal,
black test lead to the LO Terminal.
2. Press
to select the AC Voltage measurement function.
3. Choose the appropriate measurement range.
4. Setup the AC Filter.
Press Æ Filter, to setup the AC Filter Bandwidth (Default value: Mid).
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.
