to calibrate the temperature readings taken by the ATC probe. Since the temperature offset calculated during the
calibration is applied to all future temperature measurements, recalibrate if a different ATC probe is used.
Temperature calibration is for the calibration of an ATC probe (separate or built in to a pH electrode or ORP
electrode), the solution temperature measured by a DO probe, the membrane temperature measured by a DO probe
