Calibration
The 3216 series of controllers are calibrated for life at manufacture, there may however be
sensor or other system errors, which affect the accuracy of the measured temperature.
Customer calibration can be used to compensate for these errors.
Dual Offset
Dual point calibration uses two offset values at two corresponding temperatures; this
changes the calibration linearly as the temperature increases or decreases.
