PARAMETER SETUP: DEFAULT TEMPERATURE

To eliminate temperature errors associated with the pH electrode, attach an automatic temperature
compensation (ATC) probe for best accuracy. Without temperature compensation, pH accuracy will
decrease as samples deviate from 25 ºC and pH 7. The factory default setting is 25 °C / 77 °F.
If you are not using an ATC probe or the ATC is removed from the meter, the default temperature will be
used instead. The default temperature range is -10 °C to 110 °C.
If you are measuring the pH of a solution that is not 25 °C and you are not using an Automatic
Temperature Compensation (ATC) probe, enter the temperature value of the solution for best results.
The manual temperature compensation (MTC) value will be visible on the screen. The default temperature
can be set from -5 °C to 105 °C.
To Set Default Temperature:
1. Select temperature units by touching the appropriate unit button: C (Celsius), F (Fahrenheit) or
K (Kelvin).
2. Touch the Default Temperature box and use the numeric keypad to enter the desired default
temperature (-5 °C to 105 °C).
3. Press Enter in the keypad to return to pH (pH FET) Setup screen.
Tip: Using an ATC probe will override any value entered
The measured temperature will be used by the meter to determine the pH reading.
