First of all, 100 (decimal value) has to be subtracted from selected code at position
164-167. After conversion into binary notation, the sensor can be easily identified:
Bit 1: Sensor is in the calibration mode.
Bit 2: Sensor has not completed the learning phase of the temperature compensation
algorithm.
Bit 3: The value of

r
is <1.8. Is there air in the measuring chamber?
Bit 4: The temperature compensation for

r
is incorrect.
Bit 5: The temperature compensation for

r
is incorrect.
Bit 6: Maximum measuring range exceeded.
Example 1:
Selected Value
= „c106“
Code = 106 - 100 = 6

Conversion in binary representation: 110
Bit 6 Bit 5 Bit 4 Bit 3 Bit 2 Bit 1
0 0 0 1 1 0
Bit 2 = 1: Sensor is still in the temperature-learning phase.
Bit 3 = 1:

r
is <1.8. Are there air inclusions in the measuring chamber?
Example 2:
Selected Value
= „c100“
Code = 100 - 100 = 0

Conversion in binary representation: 0
Bit 6 Bit 5 Bit 4 Bit 3 Bit 2 Bit 1
0 0 0 0 0 0
No error.
