Chapter 7. Calibrating and Verifying Sensors
Kaye Validator AVS User’s Manual 83
The stability calculation begins once the temperature reference is within 5 degrees of the
setpoint. Sensor and IRTD readings are displayed on the Data screen with a red background
until they reach stability. To achieve stability, the IRTD and all sensors must meet the
stability criteria defined in the setup.
When stable, the sensor and IRTD readings change to a green background. If any sensors fail
to reach stability, the calibration process remains there.
To terminate the calibration process, press Cancel.
7.4.3 Calculate Deviation of Uncalibrated Sensors
When the IRTD and all sensors reach stability, the Kaye Validator AVS calculates deviation by
comparing each uncalibrated sensor to the IRTD, and then logs the stability and uncalibrated
deviation data to the calibration report file. The Kaye Validator AVS marks any sensor outside
the deviation criteria as failed. When uncalibrated deviation is complete, the Kaye Validator
AVS calibrates all sensors that passed uncalibrated deviation at the low setpoint.
7.4.4 Calculate Deviation of Calibrated Sensors
The Kaye Validator AVS then calculates calibrated deviation. The corrected results for each sensor
are compared to the IRTD, and logged and displayed on the Data screen every 5 or 10 seconds as
per display rate for the time period specified in the setup. Sensors that fail the calibrated deviation
evaluation are displayed with a red background, and marked as failed in the calibration report file.
7.4.5 Data Logging Complete at Setpoint
When the Kaye Validator AVS finishes logging the corrected results, it automatically sets the
Kaye temperature reference to the high setpoint and repeats the calibration process. When the
calibration process is complete for the high setpoint, the Kaye Validator AVS automatically
sets the Kaye temperature reference to the check setpoint. The only difference between the
low and high setpoint calibration and the check setpoint is that calibration offsets are not
changed during check setpoint.
