To Measure DC Voltage

The following shows the system connections and selection of measurement functions.

This practice provides a guide to get familiar with the DC Voltage measurement

technique.

Figure 1- 6 DC Voltage Measurement Data Interface

Table1- 1 DC Voltage Measurement Characteristics

Five Ranges

200mV, 2V, 20V, 200V, 1000V

Max Resolution

100nV

Input Protection

1000V on all ranges (HI Terminal)

Configurable

Parameters

Range, DC impedance, Null value

Steps:

1. Connect the test leads as shown in Figure 1- 7; red test lead to the HI Terminal,

black test lead to the LO Terminal.

2. Press to select the DC Voltage measurement function.

3. Choose the appropriate measurement range.

4. Setup the DC impedance.

Press  Res, to setup the DC input impedance (Default value: 10MΩ).

5. Set the Null value.

Null computing will be an option operation, it could be setup in accordance with

user demand. If user does not implement Null computing, this parameter is not

required. (To know the specific setting methods of the Null value setting, please

refer to Chapter 2 “To Set up Measurement Parameters”, Null computing)Lead
