Temperature
7.6.1
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. 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. Adjustment to 0.0% will not correct for
temperature effects so the displayed value will be the actual value at the displayed
temperature.
From measurement mode
1. Press
SETUP key to enter Set Up mode.
2. Press
the
MI/
S or MR/T keys to scroll through
subgroups until you view parameter P5.0.
3. Press
the
ENTER key to select parameter 5.1. The
display shows “t.CO” on the upper display.
4. Press
the
ENTER key again. The upper display
shows the temperature coefficient and the lower
display shows “t.CO”.
5. Press
the
MI/
S or MR/T keys to select the
temperature coefficient of your solution.
6. Press
the
ENTER key to confirm selection and to
proceed to step 3 of P5.2. 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” on page 47.
