Introduction
This appendix contains detailed information on the various Model 2303, 2303B, and
2303-PJ remote calibration commands, calibration error messages, and methods to detect the
end of each calibration step.
Section 2
of this manual covers detailed calibration procedures.
Command summary
Table B-1 summarizes calibration commands. These commands are covered in detail in the
following paragraphs.
* 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 per
formed in the proper sequence.

Remote calibration command summary
Command
Description
:CALibration
Calibration subsystem.
:PROTected
Cal commands protected by password.
:CODE '<code>'
Unlock cal; changes code if cal is already unlocked. (Default
code: KI002303.)
:COUNt?
Query number of times 2303 has been calibrated.
:DATE <yyyy>,<mm>,<dd>
Program calibration year, month, day.
:DATE?
Query calibration year, month, day.
:INIT
Initiate calibration (must be sent before other cal steps).
:SAVE
Save calibration data to EEPROM.*
:LOCK
Lock out calibration. (Abort if calibration is incomplete.)
:STEP0 <nrf>
Output full-scale voltage (14V).
:STEP1 <nrf>
Calibrate output voltage setting using external DMM reading.
:STEP2 <nrf>
Calibrate voltage measuring using external DMM reading.
:STEP3
Perform DVM input full-scale (14V) cal.
:STEP4 <nrf>
Output current (1.9A) for 5A full-scale cal.
:STEP5 <nrf>
Calibrate output current limit using calculated current.
:STEP6 <nrf>
Calibrate 5A measurement range using calculated current.
:STEP7
Output 5mA (500mA, Model 2303-PJ) nominal current for 5mA
(500mA) range full-scale cal.
:STEP8 <nrf>
Calibrate 5mA (500mA, Model 2303-PJ) measurement range
using calculated current.
