(CALibration:PROTected:LLEVel):SWITch?
Purpose
To request the state of the low-level calibration lock.
Format
:cal:prot:llev:swit?
Response
0 Low-level calibration locked.
1 Low-level calibration unlocked.
Description
:SWITch? query requests the status of the low-level calibration lock from the instrument.
This :SWITch? query should not be confused with the :SWITch query that requests the sta-
tus of the comprehensive calibration lock (see paragraph 3.3.1).
Programming note
To unlock low-level calibration, hold in the CAL switch while turning on instrument power.
