5.2 Manual Temperature Compensation
IMPORTANT: For manual compensation, you must
disconnect the temperature probe. The [ATC] annunciator
will disappear from the LCD.
1. Switch the meter on. Press the MODE key to select
[TEMP] mode.
2. Press the CAL/MEAS key to enter Temperature
calibration mode. The CAL indicator will appear above
the primary display.
3. The primary display shows the current pH reading and
the secondary display shows the default temperature
value 25 ºC.
4. Check the temperature of your sample using an
accurate thermometer.
5. Press the " or ! keys to set the temperature to the
measured value obtained from step 4.
6. Press CON to confirm the selected temperature. The
[CON] indicator will flash momentarily.
7. Press the CAL/MEAS key to exit and return to pH
measurement mode.
The meter will now compensate pH readings for the
manually set temperature.
NOTE: To exit this program without confirming the manual
temperature compensation value, DO NOT press CON in
step 6. Press CAL/MEAS instead.
