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 
200mV, 2V, 20V, 200V, 750V 
750VRMS on all ranges (HI Terminal) 
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   
user demand. If user does not implement Null computing, this parameter is not   
required, direct implementation of the next step.
