For simple offset type calibration simply induce the signal into the analog input and make sure the
SFC332L is reading it. After you verify that the SFC332 recognized the analog input, enter the correct mA
reading, and then click OK. The offset type calibration is mainly used when a small offset adjustment
needs to be changed in the full-scale reading. The offset will apply to the zero and span. Offset is the
recommended method for calibrating the temperature input.

To perform full calibration be prepared to induce zero and span type signal.
1. Induce the low end signal i.e. 4mA in the analog input.
2. Click inputs to be calibrated under calibration menu, click full calibration, enter the first point
- the analog input value i.e. 4mA, and then click OK button.
3. Now be ready to enter the full-scale value. Simply induce the analog signal and then enter
the second value i.e. 20mA, and then click OK button
4. Induce live values to verify the calibration .
