Chapter 6 Temperature Calibrationto calibrate the temperature readings taken by the ATC probe. Since the temperature offset calculated during thecalibration 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, ORP electrode orsource icon, set the manual temperature value using the Manual Temp Value menu. The temperature calibration menuis not accessible unless an ATC probe is connected to the meter. .2. Press , , or to highlight pH Channel or COND Channel and press f3 (select).3.
