5.1 Taking pH Measurements
5.1.1 Automatic Temperature Compensation
Automatic Temperature Compensation only occurs when a compatible temperature sensing
element is plugged into the meter.
If there is no temperature sensor plugged into the meter, the default manual temperature
setting is 25 °C . You can manually set the temperature to match your working conditions
using a separate thermometer.
For automatic temperature compensation (ATC) simply
plug the temperature probe into the meter (see page 6
for directions). The ATC indicator will light up on the
LCD. See figure on right.

NOTE
The temperature sensing element must be in the
sample that you are calibrating or measuring.
