2. Temperature Calibration
2.1 About Temperature Calibration
It is important to ensure that temperature calibration is carried out prior to pH,
conductivity and DO calibration since temperature readings affect the accuracy
of pH, conductivity and DO measurements. You need to perform temperature
calibration only if the temperature value displayed on the meter is different from
that of a calibrated thermometer or if cell constant setting is changed. A
temperature offset calibration of ± 5 °C/± 9 °F from the default reading is
allowed for ATC mode.
The built-in temperature sensor of conductivity and DO probes are factory
calibrated. The built-in ATC probe of the conductivity cells can be used for
temperature readout and compensation of the pH values. DO in mg/L is
dependent on temperature, so it is first necessary to calibrate or verify the
temperature reading. Calibrate the probes only if you suspect temperature
errors may have occurred over a long period of time or if you have a
