TEMPERATURE COMPENSATION
Conductivity measurements are temperature dependent. The degree to which temperature affects conductivity varies from solution to solution. Seawater typically has a temperature correction factor of 2.1 to 2.3 %/C. In order for the PM2 to automatically compensate for changes in conductivity as the temperature of the water changes, you must connect a temperature probe to the PM2 and set the temperature compensation as described below. The temperature probe connected to the Apex Base Module cannot be used for automatic temperature compensation on the PM2.
WARNING: Temperature compensation value MUST be set to 0.0 if no temperature probe is attached to the PM2
To set the Temperature Compensation:
Apex Display: Setup – Cond Setup – Temp Comp – use the up/down arrow keys to select the temperature compensation in %/C, press OK when done or Exit to discard changes.
