Chapter 4 Features and Functions
Scanning
You can set the scan interval to any value between 0 seconds
and 99:59:59 hours (359,999 seconds), with 1 ms resolution.
Once you have initiated the scan, the instrument will continue
scanning until you stop it or until the scan count is reached.
See "Scan Count" on page 86 for more information.
Mx+B scaling and alarm limits are applied to measurements during
a scan and all data is stored in non-volatile memory.
The MEASure? and CONFigure commands automatically set the
scan interval to immediate (0 seconds) and the scan count to 1 sweep.
From the front panel, a Factory Reset (Sto/Rcl menu) sets the scan
interval to 10 seconds and the scan count to continuous. From the
remote interface, a Factory Reset (*RST command) sets the
scan interval to immediate (0 seconds) and the scan count to 1 sweep.
