In the event of a sensor error, the following codes may appear on one of the three LCD rows instead of the measured value
E 2C
.........Initialisation error at the sensor
E 27
.........Faulty calibration data
E 36
.........Channel disabled (e.g. channel configured in the LCD,
but sensor logged off or removed)
E 50
.........Value to be displayed too large to fit on display
E 51
.........Value to be displayed too small to fit on display
E 52
.........Channel value in the saturation (upper limit)
E 53
.........Channel value in the saturation (lower limit)
E 54
.........Data error. Received data are not plausible
E 55
.........Measurement not possible of sensor not reachable
