*The temperature coefficient for the other settings must be calculated
individually according to different conditions.
*If the temperature coefficient or the difference between the environmental
temperature and the required temperature exceeds normal operation, after
calculating the compensation, the variation to the reading value will be
significant.
*When using the PT-100 temperature sensor for temperature measurements,
the accuracy of the sensor (typical accuracy of <±0.5ºC) should also be taken
into account and calculated for.
*Accuracy for Measuring current is
±3%.
