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 Terminal)

Configurable

Parameters

Range, AC Filter, 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  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
