Registers 0x1020 to 0x1027, Sensor model, String of 16 characters. There are 8
registers with two ASCII encoded characters per register containing the sensor model
name. The decoding is explained in Appendix 9.12 of this manual.
Register 0x1028, Sensor serial number.
Register 0x1029 + 0x102A, Sensor sensitivity, the sensitivity of the sensor in x 10
-6
V/(W/m²). Format of data is float.
Register 0x102B, Response time, the response time of the sensor as measured in the
factory in x 0.1 s. The value must be divided by 10 to get the value in s.
Register 0x102C, Sensor electrical resistance, returns the electrical resistance measured
during the sensor calibration. The resistance is in x 0.1 Ω and must be divided by 10 to
get the value in Ω.
Register 0x102E + 0x102F, Sensor calibration date, last sensor calibration date, from
which the sensitivity in register 41 and 42 was found, in YYYYMMDD.
