Appendix B: Calibration Reference Model 2308 Portable Device Battery/Charger Simulator User’s Manual
Introduction
This appendix contains detailed information on remote calibration commands, calibration error
messages, and methods to detect the end of each calibration step.
Section 13 of this manual contains detailed calibration procedures.
Command summary
Table B-1 summarizes calibration commands. These commands are described in detail in the
following paragraphs.
Miscellaneous commands
Miscellaneous commands are those commands that perform such functions as saving calibration
constants, locking out calibration, and programming date parameters.
:CODE
(:CALibration:PROTected:CODE)
Purpose To unlock calibration so that you can perform the calibration procedure.
Format :cal:prot:code '<code>'
Parameter Up to an 8-character ASCII string, including letters and numbers.
Description The
:CODE
command sends the calibration code and enables calibration when
performing these procedures via remote. The correct code must be sent to the
unit before sending any other calibration command. The default remote code is
KI002308.
Example
:CAL:PROT:CODE 'KI002308'
Send default code of KI002308.
NOTE The
:CODE
command should be sent only once before performing calibration.
Do not send :CODE before each calibration step.
To change the code, first send the present code then send the new code.
The code parameter must be enclosed in single quotes.

Command Description
:CALibration Calibration subsystem.
:PROTected Cal commands protected by password.
:CODE '<code>' Unlock cal; changes code if cal is already unlocked (default
code: KI002308).
* Calibration data will not be saved if:
1. Calibration was not unlocked with
:CODE
command.
2. Invalid data exists. (For example, cal step failed or was aborted.)
3. Incomplete number of cal steps were performed.
4. Calibration was not performed in the proper sequence.
