During start up, the calibration of the thermometer’s circuit is checked and the result is briefly displayed to
show the calibration result.
“CAL” and “-0-” indicate that the instrument performs within specifications.

the sensor of the thermometer. It is recommended to check the sensor by performing an ice test or
comparative test against a reference thermometer.
