How often do the CA-CALC™ Combustion Test Instruments need recalibration?
A baseline calibration is performed during the warm up cycle each time the instrument is powered up if the warm up is not bypasses by the operator. This baseline calibration recalibrates the zero point for most sensors and the span of oxygen to 20.9%. TSI recommends annual full recalibration of the sensors as a minimum. Recalibration services are available through TSI, through a local calibration facility or by anyone with a calibration kit. If recalibration is done at the factory, the instrument is cleaned and inspected in addition to the full instrument calibration. Heavy use of the instrument would warrant more frequent recalibration.
