Setting the temperature coefficient (P5.1)
The temperature coefficient is the amount of change in conductivity per degree of temperature; it is
expressed in percent per °C. 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.
Meter default is 2.1% per °C. By setting the temperature coefficient to 0.0%, the meter will not apply
any compensation but will display actual temperature.
