The voltmeter functions include AC, DC and AC+DC measurement. This 
instrument offers true RMS AC voltage measurement that provides 
accurate measurement for any input signal. For input signal AC with DC 
offset, you are recommended to use AC+DC measurement. 
To perform voltage measurement, see the following instructions:
1 Press   button to access meter menu.
2 Press F1 to access voltmeter submenu.
3 In the voltmeter submenu, press F1 to select DC, AC or AC+DC 
measurement function.
4 Connect the red test lead to the   input terminal and the black 
test lead to the COM terminal.
5 Probe the test point of the circuit under test. 
6 Read the voltage reading from the display. The display indicates the 
proper decimal point, value and symbols.
7 To perform relative function, refer to “Relative Function 112” section in 
this chapter.
