(c) Press to enter the next parameter setting or press to return to measurement mode.
(d) If you need to do calibration for other conductivity electrode whose constant is not 1.0, e.g. conductivity
electrode with constant 10.3, you should enter constant setting P2 to set the constant to be “10”, then
enter P5 mode and set the constant to be 10.3.

Temperature compensation coefficient
The temperature compensation coefficient of the meter setting is 2.0%/°C. However, the conductivity
temperature coefficient is different from solutions and concentration. Please refer to Table-11 and the
data collected during testing. Do the setting in P4. (see Section 7.6.4 for more).
Note: When the coefficient for the temperature compensation is set to 0.00 (no compensation), the
measurement value will be based on the current temperature.
