P3.3: Select temperature compensation
This controller features selectable automatic temperature compensation (ATC) or
manual temperature compensation (MTC). ATC automatically compensates for
temperature fluctuations; MTC let you select a specific value at which temperature
will be compensated. ATC readings require a temperature sensor.

mode. When set for ATC, the pH 200 will display temperature if a 100 Ω Pt 100
sensor is connected.
