Table 5-13. Range and Measurement Rate Commands and Queries (cont.)
Command Description
RANGE1?
RANGE2?
RATE <speed>
RATE?
Returns the range presently selected on the primary display.
Returns the range presently selected on the secondary display. If the secondary
display is inactive, an Execution Error is generated.
Sets the measurement rate to <speed>. <speed> is either "S" for slow (2.5
readings/second), "M" for medium (5 readings/second), or "F" for fast (20
readings/second). "S", "M", and "F" can be sent as either upper- or lower-case letters.
Any other entry for <speed> generates an Execution Error.
Returns <speed> as "S" for slow (2.5 readings/second), "M" for medium (5.0
readings/second), or "F" for fast (20 readings/second).
Measurement Queries
The commands in Table 5-14 cause the meter to return readings shown on the primary
and/or secondary displays.
Table 5-14. Measurement Queries
Command Description
MEAS1?
MEAS2?
MEAS?
VAL1?
VAL2?
VAL?
Meter returns the value shown on the primary display after the next triggered
measurement is complete
Meter returns the value shown on the secondary display after the next triggered
measurement is complete If the secondary display is off, an Execution Error is
generated.
If both displays are on, meter returns the value shown on both displays after the next
triggered measurement is complete in the format selected. These values are
separated by a comma (format 1); or a space, measurement units, a comma and
space (format 2). See FORMAT command in Table 5-15.
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.
Meter returns the value shown on the primary display. If the primary display is blank,
the next triggered measurement is returned.
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.
If both displays are on, meter returns the value shown on both displays in the format
selected. These values are separated by a comma (format 1); or a space,
measurement units, a comma and space (format 2). See FORMAT command in Table
5-15.
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.
