Commands controlling the Auto-Calibration Function:
CL AUTO-CALIBRATION
CONTROL Comment
Description: Allows the user to initiate auto-calibration and to store calibration values.
Usage: CL [option]
Command
combinations:
CLB Begin auto-calibration. Prior to auto-calibration, the calibration
coefficients are automatically restored from flash memory.
CLS Save calibration coefficients to EEPROM starting at address
0x0004
CLC Use machine-readable calibration protocol
CLR Restore calibration coefficients from EEPROM
CLD Restore coefficients from flash memory
Example: CLB Starts auto-calibration and saves data automatically.
Before starting the auto-calibration process, target values for voltage, duration and current must be entered in
MPU RAM (see section 1.9.5) and the target voltage and current must be applied constantly during calibration.
Calibration factors can be saved to EEPROM using the CLS command.
Commands controlling the Pulse Counter Function
CP PULSE-COUNT CONTROL Comment
Description: Allows the user to control the pulse count functions.
Usage: CP [option]
Command
combinations:
CPA Start pulse counting for time period defined with the CPD
command. Pulse counts will display with commands M15.2,
M16.2
CPC Clear the absolute pulse count displays (shown with
commands M15.1, M16.1)
CPDn Set time window for pulse counters to n seconds, n is inter-
preted as a decimal number.
Example: CPD60 Set time window to 60 seconds.
Pulse counts accumulated over a time window defined by the CPD command will be displayed by M14 after the
defined time has expired.
M14 will display the absolute pulse count for the W and VAR outputs. These displays are reset to zero with the
CPC command (or the XRAM write )1=2).
Commands for Identification and Information:
I INFORMATION MESSAGES Comment
Description: Allows user to read information messages.
Usage: I Displays complete version information
The I command is mainly used to identify the revisions of Demo Code and the contained CE code.
