Description Recommendation
00 Normal mode, static temperature
10 Bit 0 Warm-up Do not perform calibration.
11 Bit 0 Too many UART interruptions Do not perform calibration or zeroing. Decrease request frequency.
21 Bit 4 Fast temperature change Do not perform calibration or zeroing.
22 Bit 5 Sharp temperature change Do not perform calibration or zeroing.
24 Bit 4 Bit 1
Fast temperature change + Zero
shifts to negative values Do not perform calibration or zeroing.
30 Bit 2
Low signals level Do not perform calibration or zeroing.
Measuring accuracy need to be additionally verified, once
switching on of Bit 2 has been observed.
Replace the sensor if Bit2 is on constantly (> 20 min).
31 Bit 1
Zero shifts to negative values Using of dust filters is recommended to avoid moisture or dust
inside sensor. In case of moisture ingress, unmounts sensor off
device, then dry it during 4 hours minimum in warm dry location.
Make zeroing procedure and performance check.
40 Bit 6 Out of operation temperature range Check the ambient temperature.
50 Bit 1
Abrupt change of signal Do not perform calibration or zeroing.
Replace sensor, if bit1 is on constantly (> 20 min).
