P8.2 Selecting the normalization temperature
Your meter will normalize its conductivity measurements to a standard temperature
that you can select. You can adjust the normalization temperature from 15 to 30°C
(59 to 86°F). Meter default is 25°C (77°F).
From measurement mode
1. Press the Mode key to select
conductivity or TDS measurement mode.
2. Press Setup key to enter Set Up mode.
3. Press the ▲ and ▼ keys to scroll through
subgroups until you view parameter P8.0.
See figure
4. Press the ENTER key three times to
select parameter 8.2. The display shows
“t.nr” on the upper display.
See figure
5. Press the ENTER key again. The
upper display shows the normalization
temperature and the lower display
shows “t.nr”.
See figure
6. Press the ▲ and ▼ keys to select the
normalization temperature.
7. Press the ENTER key to confirm selection
and to return to the subgroup menu. Press
the CAL/MEAS key to return to measure-
ment mode.

P8.0: Temperature Settings
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 or °F. 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 or °F. Meter default is 2.1% per °C
or °F.
From measurement mode
1. Press the Mode key to select
conductivity or TDS measurement mode.
2. Press Setup key to enter Set Up mode.
3. Press the ▲ and ▼ keys to scroll through
subgroups until you view parameter P8.0.
See figure
4. Press the ENTER key to select
parameter 8.1. The display shows “T.CO”
on the upper display.
See figure
5. Press the ENTER key again.. The upper
display shows the temperature coefficient
and the lower display shows “T.CO”.
See figure
6. Press the ▲ and ▼ keys to select the tem-
perature coefficient of your solution.
7. Press the ENTER key to confirm selection
and to proceed to step 4 of P.8.2. Press the
CAL/MEAS key twice to return to meas-
urement mode.
Notes
* If you do not know the temperature coeffi-
cient of your solution you can determine
the correct value using the formula in
Appendix 3 “Calculating Temperature
Coefficients” on page 50.
