1.8.1 Additional External Compensation
To achieve the best possible accuracy, the temperature measurement information and typical
temperature dependency curves can be used for SCA100T offset and sensitivity temperature
dependency compensation. The equation of fitted 3rd order polynome curve for offset
compensation is:
Offcorr 0.0000006*T 3 0.0001*T 2 0.0039*T 0.0522
Where:
Offcorr:
T
3rd order polynome fitted to average offset temperature dependency curve
temperature in °C (Refer to paragraph 2.7 Temperature Measurement)
The calculated compensation curve can be used to compensate the temperature dependency of
the SCA100T offset by using following equation:
OFFSETcomp Offset Offcorr
Where:
OFFSETcomp
Offset
temperature compensated offset in degrees
Nominal offset in degrees
