Calibration Reference
:INIT
(:CALibration:PROTected:INITiate)
Purpose To initiate comprehensive and factory calibration procedures.
Format :cal:prot:init
Parameters None
Description The :INIT command enables Model 2750 calibration when perform-
ing these procedures over the bus. This command must be sent to the
unit after sending the :CODE command, but before sending any other
calibration command.
NOTE The
:INIT command should be sent only once before performing either DC,
AC, or factory calibration. Do not send
:INIT before each calibration step.
Example :CAL:PROT:INIT Initiate calibration.
:LOCK
(:CALibration:PROTected:LOCK)
Purpose To lock out comprehensive or manufacturing calibration.
Format :cal:prot:lock
Parameters None
Description The :LOCK command allows you to lock out both comprehensive and
manufacturing calibration after completing those procedures. Thus,
:LOCK performs the opposite of enabling calibration with the :CODE
command.
NOTE To unlock comprehensive calibration, send the
:CODE command. To unlock
manufacturing calibration, hold in the OPEN key while turning on the power.
Example :CAL:PROT:LOCK Lock out calibration.
