Chapter 7. Calibrating and Verifying Sensors
If you are performing a two-point calibration (low and high setpoints), the Kaye Validator
repeats this process. You can also specify a check setpoint in your setup. During check
setpoint, the Kaye Validator calculates and logs deviation on the calibrated sensors.
Calibration offsets are not altered unless a sensor fails at the check setpoint.
When calibration is complete, the Kaye Validator writes the calibration offsets, the serial
number of the Kaye Validator measurement board where calibration was performed, and the
SIM slot number to the SIMs. If a sensor fails at the low, high, or check setpoint, it is marked
as failed in the SIM and in the calibration report file.
Before you begin the calibration process:
•
Place the Kaye Validator in a location with stable and even temperature, not exposed to
any local heat sources (i.e., close to a sterilizer, an open door causing a draft, etc.).
Temperature variations and/or exposure to external heat sources during calibration may
cause temporary temperature measurement errors.
•
To provide maximum accuracy during the calibration process, power up the Kaye
Validator and let it run for approximately 30 minutes in the operating environment where
calibration is to be performed in order for the Kaye Validator to acclimate to the ambient
temperature.
•
Place the temperature sensors and the IRTD into the temperature reference. The
temperature reference provides the stable temperature required for sensor calibration.
7.2 Loading a Setup into the Validator
Before you begin the calibration or calibration verification process, you have to load your
setup into the Kaye Validator.
IMPORTANT:
When you load a setup with a different calibration signature (calibration
parameters and/or temperature units) than the setup currently in memory,
any sensors already calibrated will be marked as uncalibrated. If you reload
the original setup, and you have not calibrated sensors using the new setup,
the offsets are restored and the sensors are marked as calibrated.
