Chapter 6: Configuring a Temperature Zone
Calibrating the Temperature Probe
Although temperature probes are manufactured with high accuracy, some probes might show slight meas-
urement variations. The probe calibration allows you to compensate for such a variation by up to ± 10 °
F (± 5.5 °C) with an accuracy of one tenth of a degree
1. In edit mode, under the Calibration tab, click on the edit field next to the Offset button to display the
keypad.
2. Enter the impedance offset in ohms.
3. Enter the temperature offset and the low and high trouble impedances.
NOTE: Enter value from left to right and always enter a decimal value. For example, a value of 1 °F
requires you to enter 10 to obtain 1.0 °F.
Use the +/- button to change between a positive and a negative value.
For example, if a probe shows a measurement difference of + 1.3 °F from the actual temperature, you
must enter – 1.3 °F to calibrate the probe.
