Model 2700 Multimeter/Switch System User’s Manual Basic DMM Operation 3-59
[:SENSe[1]]:DATA[:LATest]?
What it does
This query will return the last reading the instrument had, regardless of what may have
invalidated that reading, such as changing ranges or functions.
Limitations
This query is fully capable of returning meaningless, old data.
When appropriate
If, for some reason, the user wanted the last completed reading, even after changing ranges
or other measurement settings, which would invalidate the old reading.
The :CALC:DATA:LATest? query is similar to the :DATA:LAT? query, but applies to
readings that have math applied to them (e.g.,:MX+B scaling).
Examples
One-shot reading, DC volts, no trigger, fastest rate
