Calibration
2 Press CAL to begin temperature calibration mode. "CA" (calibrate)
will display briefly. The un-adjusted °C value will blink.
3 Compare the measured value of the temperature probe with the reference
thermometer. Use MODE/INC to adjust the reading to the desired value.
The maximum adjustment is ± 5°C.
4 Press HOLD/ENTER to confirm the value. "CO" (confirm) will display
briefly. The meter will automatically save the calibration, cease blinking,
and begin °C measurement.
Without Temperature Probe (Manual Temperature Compensation)
If a temperature probe is not connected, the meter compensates for pH
response based on the factory default value at 25.0°C. This default temperature
can be manually adjusted using the procedure below.
For nearly all applications however, Automatic Temperature Compensation
(ATC) is recommended for best accuracy.
