Calibration
There is a specific method to make the calibration operation. It is necessary to match the source of
reference applied to or connected to the device with the wished value. At least four parameters
should be used to configure this process: CAL_POINT_HI, CAL_POINT_LO, CAL_MIN_SPAN, and
CAL_UNIT. Those parameters define the highest and lowest calibrated value for this device, the
minimum allowed span value for calibration (if necessary) and the engineering unit selected for
calibration purpose.
NOTE
TP302 has damping function implemented.
