Chapter 5 Temperature Calibration

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.)
set the manual temperature value using the Manual Temp Value menu. The temperature calibration menu is not
accessible unless an ATC probe is connected to the meter.
