SRQ
You can program the instrument to generate a service request (SRQ) when one or more
errors or conditions occur. When this indicator is on, a service request has been generated.
This indicator stays on until the serial poll byte is read or all the conditions that caused
SRQ have been cleared. See

LOCAL key

The LOCAL key cancels the remote state and restores local operation of the instrument.
Pressing the LOCAL key also turns off the REM indicator and returns the display to nor-
mal if a user-defined message was displayed.
If the LLO (Local Lockout) command is in effect, the LOCAL key is also inoperative.
For safety reasons, the OUTPUT key will still be active in LLO.

Programming syntax

The information in this section covers syntax for both common commands and SCPI com-
mands. For information not covered here, see the IEEE-488.2 and SCPI standards. See
