THE STANDARD IN PRECISION MEASUREMENT

Introduction
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 the controller. Changing calibration settings can cause errors in sensor temperature
readings and operation of the controller.
Full-Range Calibration
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.
SENSOR TYPE RANGE
THERMOCOUPLES
Calibration accuracy +/-0.1% of span or +/-oC for types J, K, T, E, N;
+/- 0.2% of span or +/-2oC for types B,R,S. Accuracy span is 1000oF (540oC) minimum.
Type J -190 to 1000 °C
Type K -200 to 1372 °C
Type N -200 to 1300 °C
Type R 0 to 1768 °C
Type S 0 to 1768 °C
Type T -200 to 400 °C
Type B 600 to 1800 °C
Type E -200 to 1000 °C
PLATINUM RTD
Calibration accuracy +/-0.1% of span. Accuracy span is 1000oF (540oC) minimum.

THERMISTOR
Calibration accuracy +/-0.4% of span or +/-0.5oC. Accuracy span is 1000oF (540oC) minimum.
YSI 400 -30 to 100 °C
YSI 700 -15 to 100 °C

Segmented Calibration
Segmented Calibration allows you to calibration between any two temperatures along the full range of the probe,
providing a more accurate reading between those temperatures. For example, placing all six (6) 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 nonlin-
earity of temperature probes.
