P5.0: Temperature
P5.1 Adjusting the temperature coefficient
The temperature coefficient is the amount of change in conductivity per degree of
temperature; it is expressed in percent per °C or °F. Entering the exact temperature
coefficient of your solution lets you accurately compensate temperature for almost
any solution*. You can adjust 0.0 to 10.0% per °C or °F. Meter default is 2.1% per °C
or °F.

Notes
* If you do not know the temperature coef-
ficient of your solution you can determine
the correct value using the formula in
