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.

 

Front-Panel Operation: To select interval scanning and set a scan

interval time (hour:minutes:seconds), choose the following item.

 

 

 

 

 

INTERVAL SCAN

To initiate the scan and store all readings in memory, press (the SCAN annunciator will turn on). Between scan sweeps,

the count-down time is shown on the front-panel (00:04 TO SCAN).

Note: To stop a scan, press and hold .

Remote Interface Operation: The following program segment configures the instrument for an interval scan.

TRIG:SOURCE TIMER

Select the interval timer configuration

TRIG:TIMER 5

Set the scan interval to 5 seconds

TRIG:COUNT 2

Sweep the scan list 2 times

INIT

Initiate the scan

Note: To stop a scan, send the ABORt command.
