3.3.6.
Calibration retention
Calibration data is saved in non-volatile memory (EEPROM) and the display does not need power to retain
calibration data.
3.3.7.
Invalid calibration
Calibration automatically makes the ITL40 a MASTER display if the calibration is valid. An invalid calibration is
determined when any calibrated point is not at a higher level than the previous calibrated point, or if the sensor
voltage falls outside of the valid minimum (0.4V) or maximum (4.8V) range.
An invalid calibration is acknowledged by flashing "X" four times and then scrolling the text "CHECK SENSOR
VOLTS" followed by a continuous scroll of the voltage detected on the sensor's signal (pin 6).
