8.9.2 P8.2: Adjusting the normalisation temperature
Your meter will normalise its conductivity measurement to a standard
temperature that you can select. This feature is useful if your samples
are consistently at a temperature other than 25°C (77 °F). You can
adjust the normalisation temperature from 15 to 30 °C (59 to 86 °F).
Meter default is 25 °C (77 F). When using non-standard normalisation
temperatures, it is important to calibrate to the value of your calibration
standard at your normalisation temperature setting. 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 two times to select parameter P8.2. The
display shows “t.nr” on the upper display.
5. Press the ENTER key again. The upper display shows the
normalisation temperature and the lower display shows “t.nr”.
6. Press the  or  key to select the normalisation temperature.
7. Press the ENTER key to confirm selection and to return to the sub-
group menu. Press CAL/MEAS key to return to measurement mode.
8.9.3 P9.0: Resetting to factory default settings (conductivity)
Program P9.0 lets you reset all parameters to factory default settings.
This clears all calibration data and any other conductivity setup functions you might have changed.
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 P9.0.
4. Press the ENTER key to enter parameter P9.0.
5. Press the  or  to toggle between NO and YES
• NO retains current settings; YES resets to factory default
settings.
6. Press the ENTER key to confirm selection and to return to the
measurement mode. Otherwise press CAL/MEAS key to return to
measurement mode without resetting to factory default.
NOTE
: To clear all pH data, see page 38. See Addendum 4 on page 49
for a table of factory default settings.
