FORMat Subsystem
During a scan, the instrument automatically adds a time stamp to all readings and stores them in reading memory.
Each reading is also stored with measurement units, time stamp, channel number, and alarm status information.
You can specify which information you want to return with the readings. Examples below show a reading in relative
and absolute format with all fields enabled.
Reading format applies to all readings being retrieved from the instrument; you cannot set the format on a
per-channel basis. CONFigure and MEASure? commands automatically disable the channel setting.
Relative format - shows the time since the start of the scan.

2

4

Absolute format - shows the time of the day with the date.
