Introduction
THERMISTOR
Table 1. Sensor Input Range
Each temperature controller has built into the operation menus a calibration gateway. This
gateway allows the temperature controller to be calibrated to six temperature points, allowing
for consistent and accurate temperature readings. The calibration process allows for both
full-range calibration and segmented calibration. Each unit comes preloaded with tested
default calibration temperature points.
WARNING: Do not enter the calibration gateway unless you have the proper calibration
equipment to calibrate the sensor inputs associated with this controller. Changing calibration
settings can cause errors in sensor temperature readings and operation of the controller.
Full-Range Calibrati on
This process provides accurate temperature measurements along the entire range of a given
type of temperature probe. Ranges of each type of temperature probe are provided on the
controllers menu screen, as well as in Table 1 below.

range of the probe, providing a more accurate reading between those temperatures. For
example, placing all six calibration points between 0.0°C and 600°C will yield more accurate
temperature readings between those temperatures than the full-range calibration would.
WARNING: Measurements outside the calibrated segment may be notably skewed
Default Calibration Points
Default calibration points come preloaded in the controller (also see Table 2). These points have
been selected and tested to provide accurate temperature readings across the full range. While
these calibration points can be adjusted for segmented calibration, it is not suggested that they
be changed for full-range calibration due to nonlinearity of temperature probes.
