: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.
