10. MAINTENANCE
Due to
its special design the sensor system doesn’t need specific maintenance. The
cleaning of the sensor bowl and the sensor plates should only be performed, when all
parts of the sensor have ambient room temperature, else the threads can be damaged!
Unscrew the sensor bowl from the sensor carrier carefully. After cleaning the sensor
bowl and sensor plates (Xylol, Isopropanol) grease has to be applied to both threads
(inner and outer thread of the bowl and carrier), else threads can be damaged! Damage
of the sensor due to incorrect treatment is not covered by warranty!
11. CODES
11.1 RS232 (WSens-Software)
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:
Code = 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 temp. learning phase.
Bit 3 = 1:

r
is <1,8. Are there air inclusions in the measuring chamber?
Example 2:
Code = 0
Bit 6 Bit 5 Bit 4 Bit 3 Bit 2 Bit 1
0 0 0 0 0 0
No error.
