Table 4-12 describes measurement queries, which are shown on the primary and/or 

secondary displays. 

MEAS1? 

Meter returns the value shown on the primary display after the next triggered 
measurement is completed. 

MEAS2? 

Meter returns the value shown on the secondary display after the next 
triggered measurement is completed. If the secondary display is off, an 
Execution Error is generated. 

MEAS? 

If both displays are on, Meter returns the value shown on both displays after 
the next triggered measurement is completed in the format selected. (See 
FORMAT command in Table 4-15.) Refer to the following examples for each 
format: 

Example of Format 1: +1.2345E+0,+6.7890E+3<CR><LF> 

Example of Format 2: +1.2345E+0 VDC, +6.7890E+3 ADC<CR><LF> 

If the secondary display is not on, MEAS? is equivalent to MEAS1? 

Note: If MEAS is used in external trigger (TRIGGER 2 through TRIGGER 5), 
unexpected results will be obtained. 

VAL1? 

Meter returns the value shown on the primary display. If the primary display is 
blank, the next triggered measurement is returned. 

VAL2? 

Meter returns the value shown on the secondary display. If the secondary 
display is blank, the next triggered measurement is returned. If the secondary 
display is off, an Execution Error is generated. 

VAL? 

If both displays are on, Meter returns the value shown on both displays in the 
format selected. (See FORMAT command in Table 4-15.) Refer to the 
following examples for each format: 

Example of Format 1: +1.2345E+0,+6.7890E+3<CR><LF>  

Example of Format 2: +1.2345E+0 VDC, +6.7890E+3 ADC<CR><LF>  

If the secondary display is not on, VAL is equivalent to VAL1. If a display is 
blank, the next triggered measurement on that display (or displays) is 
returned.
