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
