Selecting 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 readings will manually temperature com-
pensate. You can select any temperature between 0 and
100°C (32 and 212°F). Default value is 25°C (77°F).
To select a manual temperature compensation value:
1.
Press the MODE key to select the measurement
mode in which you need to use manual temperature
compensation.
2.
If necessary, select ATC off.
pH: see NOTE on page 15
Conductivity or TDS: see page 20
When ATC is off, the ATC indicator disappears from the
lower right corner of the display.
3.
Press the CAL/MEAS key to enter calibration mode. The
CAL indicator will appear above the primary display.
See Figure 28
4.
While in 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 last set temperature value.
See Figure 29
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.
See Figure 30
7.
Press ENTER to confirm the selected temperature and to
return to measurement mode.
The meter will now compensate readings for the manually
set temperature.
Notes
To exit this program without confirming the manual tempera-
ture compensation value, DO NOT press ENTER in step 7.
Press CAL/MEAS instead.
Setting the manual temperature compensation value for
conductivity or TDS will change the manual temperature
compensation value for pH to the same value, and vice
versa.
