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.

200mV, 2V, 20V, 200V, 1000V 
 
Basic measurement: 
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
