AUTOMATIC TEMPERATURE COMPENSATION (ATC)

The meter is recommended to use PHE-860 three in one epoxy
combination probe with a temperature sensor probe for the automatic

temperature compensation (ATC), the meter is capable of taking

measurements with automatic or manual temperature compensation.

Ensure the PHE-860 probe is plugged into the meter for ATC,
otherwise use a standard
additional temperature probe, the probe must be submersed in
the liquid you are measuring.

If there is no temperature sensor plugged into the meter, the default
manual temperature setting is automatically 25 degree C
set the temperature to match your working conditions using a
separate thermometer and record the working condition (temperature
of the liquid) to convert the
