5.2.3 Setting a manual temperature compensation value
To use manual temperature compensation, you need to enter the temperature value of your
process into the meter. This is the value at which reading will manually temperature
compensates. You can select any temperature between 0 and 100
°C (32 to 212 °F). Default
value is 25
°C (77 °F).
To select a manual temperature compensation value
1. Switch the meter on. Press the MODE key to select
conductivity or TDS measurement mode.
2. If necessary, select ATC off as described in section
5.2.2. The ATC indicator will not appear on the
display.
3. Press the CAL/MEAS key to enter conductivity or
TDS calibration mode. The CAL indicator will
appear above the primary display.
4. While in conductivity (or TDS) calibration mode,
press the MODE key to enter temperature
calibration mode. The primary display shows the
current temperature setting and the secondary
display shows the default value 25 °C (77 °F) or its
last set value.
5. Check the temperature of your sample using an
accurate thermometer.
6. Press the or keys to offset the temperature to
the measured value from step 5.
7. Press ENTER to confirm the selected temperature
and to return to the conductivity measurement
mode. See Figure 19.
The meter will now compensate conductivity or TDS
readings for manually set temperature.
NOTES:
To exit this program without confirming the manual temperature compensation value, DO NOT
press ENTER in step 6. Press CAL/MEAS instead.
Setting the manual temperature compensation value for conductivity will change the manual
temperature compensation value for pH to the same value, and vice versa.
