Trigger Delay
You can insert a delay between the trigger signal and each sample that follows.
This may be useful in applications where you want to allow the input to settle
before taking a reading, or for pacing a burst of readings. If you do not specify a
trigger delay, the meter automatically selects a delay for you.
– Delay range: 0 to 3600 seconds. The default trigger delay is automatic; the
delay is determined by function, range, and integration time (see also
“Automatic Trigger Delays” on page 102).
– The trigger delay is stored in volatile memory; the meter selects an automatic
trigger delay when power has been off or after a remote interface reset. The
CONFigure and MEASure? commands set the trigger delay to automatic.
– If you specify a delay other than automatic, that same delay is used for all
functions and ranges.
– If you have configured the meter to take more than one reading per trigger
(sample count > 1), the specified trigger delay is inserted between the trigger
and each reading.
– Front Panel operation: You can use an automatic trigger delay or you can
specify a delay in seconds. Set the delay time in the 2: TRIG DELAY command of
the TRIGger menu.
If an automatic trigger delay is enabled, “AUTO” is displayed momentarily
before the actual number of seconds is displayed.
