Model 2701 Service Manual Calibration Reference B-5
:INIT
(:CALibration:PROTected:INITiate)
Purpose
To initiate comprehensive and factory calibration procedures.
Format
:cal:prot:init
Parameter
None
Description
The
:INIT
command enables Model 2701 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
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.
