Reading Format Commands
During a scan, the instrument automatically adds a time stamp to
all readings and stores them in non-volatile memory. Each reading is
stored with measurement units, time stamp, channel number, and
alarm status information. You can specify which information you want
returned with the readings (from the front panel, all of the information
is available for viewing). The reading format applies to all readings
being removed from the instrument from a scan; you cannot set the
format on a per-channel basis. The following is an example of a reading
stored in memory with all fields enabled (relative time is shown).
FORMat
:READing:ALARm {OFF|ON}
:READing:ALARm?
Disable (default) or enable the inclusion of alarm data with data
produced by READ?, FETCh?, or other queries of scan results.
This command operates in conjunction with the other FORMat:READing
commands (they are not mutually exclusive). The :ALAR? query reads
whether or not alarm data is included. Returns “0” (
OFF) or “1” (ON).
FORMat
:READing:CHANnel {OFF|ON}
:READing:CHANnel?
Disable (default) or enable the inclusion of the channel number with
data produced by READ?, FETCh?, or other queries of scan results.
This command operates in conjunction with the other FORMat:READing
commands (they are not mutually exclusive). The :CHAN? query reads
whether or not the channel is included. Returns “0” (
OFF) or “1” (ON).
