:INIT (:CALibration:PROTected:INITiate)
Purpose To initiate comprehensive and factory calibration procedures.
Format :cal:prot:init
Description The :INIT command enables Model 2010 calibration when performing these
procedures over the bus. This command must be sent to the unit after sending
the :CODE command, but before sending any other DC, AC, or
manufacturing 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

locked/unlocked state. Calibration must be enabled sending the :CODE
