B-6 Calibration Reference
:INIT
(:CALibration:PROTected:INITiate)
Purpose To initiate comprehensive and factory calibration procedures.
Format :cal:prot:init
Parameter None
Description The :INIT command enables Model 2015 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 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
Parameter None
Description The :LOCK command allows you to lock out both comprehensive and man-
ufacturing calibration after completing those procedures. Thus,
:LOCK per-
foms the opposite of enabling calibration with the
:CODE command.
NOTE To unlock comprehensive calibration, send the :CODE command. To unlock manufac-
turing calibration, hold in the SOURCE key while turning on the power.
Example :CAL:PROT:LOCK Lock out calibration.
