Where:
## represents the set value (## can be 0 to 9).
Description
This command will select which calibration set you are accessing. The Led analyser is capable
of storing ten (10) separate user Calibration sets on the board.
The command SETCALIBRATION# stores the Calibration sets both on RAM and on EEPROM
(stays after power cycle but limits the number of set command operations to ~ 100K).
The command PUTCALIBRATION# only stores them on RAM and the analyser will default back
to what values were stored in the EEPROM after a power cycle.
The default calibration set is 0
Example:
If you want to select set No.3
setcalibration3
OK
Example:
If you want to select set No.3
putcalibration3
OK
The command GETCALIBRATIONSET will return the number of which stored Calibration set of
values are currently selected.
Example:
calibrationset3
