8.9 P8.0: Temperature
8.9.1 P8.1: Selecting the temperature coefficient
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. The meter default is 2.1% per °C. A temperature coefficient
setting of 0.0% does not apply a correction factor to the reading for
temperature.
From measurement mode
1. Press the MODE key to select conductivity measurement mode.
2. Press SETUP key to enter Setup mode.
3. Press the or key to scroll through sub-groups until you view
parameter P8.0.
4. Press the ENTER key to select parameter P8.1. The display shows
“t.CO” on the upper display.
5. Press the ENTER key again. The upper display shows the
temperature coefficient and the lower display shows “t.CO”.
6. Press the or key to select the temperature coefficient of your
solution.
7. Press the ENTER key to confirm selection and to proceed to step 3
of P8.2. Press the CAL/MEAS key twice to return to measurement
mode.
NOTE: *If you do not know the temperature coefficient of your solution
you can determine the correct value using the formula in Addendum 3
“Calculating Temperature Coefficients” on page 48.
