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
co
de: KI002306.)
:COUNt? Query number of times 2306 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 Ch. 1 full-scale voltage (14V).
:STEP1 <nrf> Calibrate Ch. 1 output voltage using external DMM reading.
:STEP2 <nrf> Calibrate Ch. 1 voltage measuring using external DMM reading.
:STEP3 Perform Ch. 1 DVM input full-scale (14V) cal.
:STEP4 <nrf> Output current (1.9A) for Ch. 1 5A full-scale cal.
:STEP5 <nrf> Calibrate Ch. 1 output current limit using calculated current.
:STEP6 <nrf> Calibrate Ch. 1 5A measurement range using calculated current.
:STEP7 Output 5mA nominal current for Ch. 1 5mA range full-scale cal.
:STEP8 <nrf> Calibrate Ch. 1 5mA measurement range.
:STEP9 <nrf> Output Ch. 2 full-scale voltage (14V).
:STEP10 <nrf> Calibrate Ch. 2 output voltage setting using DMM reading.
:STEP11 <nrf> Calibrate Ch. 2 voltage measuring using external DMM reading.
:STEP12 Perform Ch. 2 DVM input full-scale (14V) cal.
:STEP13 <nrf> Output current (1.9A) for Ch. 2 5A full-scale cal.
:STEP14 <nrf> Calibrate Ch. 2 output current limit using calculated current.
:STEP15 <nrf> Calibrate Ch. 2 5A measurement range using calculated current.
:STEP16 Output 5mA nominal current for Ch. 2 5mA range full-scale cal.
:STEP17 <nrf> Calibrate Ch. 2 5mA measurement range.
Calibration Reference C-3
* Calibration data will not be saved if:
1. Calibration was not unlocke
d 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.
