Scanning Overview

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).

1 Reading with Units (26.195 °C)

3 Channel Number

2 Time Since Start of Scan (17 ms)

4 Alarm Limit Threshold Crossed

 

(0 = No Alarm, 1 = LO, 2 = HI)

FORMat

:READing:ALARm {OFFON}: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 {OFFON}: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).
