Bits
Oxix
Status bit { on = 1 & off = 0 }
Bit 1 = sensor - replace sensor
Bit 2 = sensor - fix error / redo calibration point or clear all points and redo calibration
Bit 3 = sensor - temperature error (thermistor is damaged)
Bit 4 = sensor - check sensor cable
Bit 5 = sensor - check sensor wiper
Bit 6 = sensor - probe polluted => clean - if message is repeated, return probe
Bit 7 = sensor - main photo diode saturated (circuit or sensor coating damaged)
Bit 8 = sensor - main photo diode negative (excessive electrical noise or damage)
Bit 9 = sensor - reference photo diode saturated (same causes as bit 7)
Bit 10 = sensor - reference photo diode negative (same causes as bit 8)
Bit 11 = reseved - read-value is 0 (zero)
Bit 12 = reseved - read-value is 0 (zero)
Bit 13 = reseved - read-value is 0 (zero)
Bit 14 = reseved - read-value is 0 (zero)
Bit 15 = sensor - supply is to high / low. Check sensor connection
Bit 16 = sensor - temperature error (temperature is out of range)

Status bit { on = 1 & off = 0 }
Bit 1 = sensor - replace sensor
Bit 2 = sensor - fix error / redo calibration point or clear all points and redo calibration
Bit 3 = sensor - is not in solid mode - choose a unit of solid type
Bit 4 = sensor - check sensor cable
Bit 5 = sensor - check sensor wiper
Bit 6 = sensor - probe polluted => clean - if message is repeated, return probe
Bit 7 = sensor - turbidity value out of range (higher then 4000 NTU) - only implemented to
display unexpected error
Bit 8 = sensor - calibration insufficient - make another calibration on lower solid test sample
Bit 9 = sensor - calibration insufficient - make another calibration on higher solid test sample
Bit 10 = sensor - overflow - clean sensor / or check range and ensure that probe is
used to measure
Bit 11 = sensor - offset error (only implemented to display unexpected error
Bit 12 = sensor - measuring start failed - please try again
Bit 13 = sensor - measuring timeout - try again
Bit 14 = sensor - measuring adjustment missing
Bit 15 = sensor - supply is to high / low. Check sensor connection
Bit 16 = reseved and read-value is 0 (zero)
