7.9 P8.0 Temperature
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. Meter default is
2.1% per
°C.
From measurement mode
1. Press the MODE key to select conductivity
measurement mode.
2. Press SETUP key to enter Set Up mode.
3. Press the or keys to scroll through
subgroups until you view parameter P8.0.
4. Press the ENTER key to select parameter 8.1.
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 keys 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.
Notes
* 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”.
