Differential Pressure Sensor Calibration

The OV-Menu provides access to the automatic sensor calibration routine for the differential pressure sensor by means of calling the Linux-program sensorcal. The calibration routine measures the sensor offset 10 times and calculates an average value, which is stored in the I2C-Serial EEPROM on the Sensorboard. The EEPROM must be initialized once, before the serialnumber is written and the first calibration is possible.

Command Line Parameter

sensorcal -i              Initialize EEPROM. All Values will be cleared !!!
sensorcal -s [serial]     Write Serialnumber to EEPROM (6 chars)   
sensorcal -c              calibrate sensors and write values to EEPROM
