LOCK

Lock and unlock the instrument front panel control keys. The LOCK modes disable

 

the front panel keys, while placing the instrument in either REVIEW (LOCK 1),

 

MONITOR (LOCK 2) or Configuration Lock (LOCK 3). This limits instrument

 

operation to a specific mode and prevents unauthorized configuration changes. Only

 

supervisory personnel should be aware that the Fand Bkeys can be used to

 

toggle the LOCK modes on and off, except for LOCK 3, which is reset from the

 

computer interface only or by loading a non-LOCK 3 setup file.

 

 

 

LOCK modes 1 and 2 are not saved/restored in configuration files. If one of these

 

modes is active when FILE_STORE is performed, mode 0 (unlocked) is stored in the

 

file.

 

 

 

 

 

LOCK

<mode>

 

 

 

 

 

<mode> = 0,1,2,3

 

 

 

 

LOCK 0

Unlock the front panel and turn off the REM (remote) annunciator.

 

 

All key functions are

a LOCK 1, LOCK 2, or LOCK 3 condition.

 

 

 

LOCK 1

Lock the front panel in the REVIEW mode and turn on the REM

 

 

(remote) annunciator.

Only the up/down and left/right arrow

 

 

keys are unlocked to allow the review of the

minimum,

 

 

maximum, and last values of any channel. The front panel can be

 

 

unlocked by using the LOCK 0 command, or by simultaneously

 

 

pressing the front panel Fand Bkeys. The Fand B

 

 

keys can be used toggle between the locked and

unlocked

 

 

modes, while in REVIEW.

 

 

 

LOCK 2

Lock the front panel in the MONITOR mode (which must be active

 

 

or the command will generate an execution error) and turn on the

 

 

REM (remote) annunciator. Only the up/down arrow keys are

 

 

unlocked to allow the monitoring of any channel. The front panel

 

 

can be unlocked by using the LOCK 0 command, or by

 

 

simultaneously pressing the front panel Fand Bkeys. The

 

 

Fand bkeys can be used to toggle between

 

the locked

 

 

and unlocked modes, while in MON.

 

 

 

LOCK 3

Lock the channel configuration. The instrument operates normally

 

 

except keys used to configure a channel are disabled, that is , the

 

 

configuration is locked. A configuration file can be loaded; scan
