3.4 Temperature Calibration
In this calibration procedure, the ATC probe is attached to the meter and the [ATC] annunciator is displayed on the right
hand side of the LCD.
1. Dip the temperature probe into a solution of known temperature,
such as a temperature bath for a few minutes until the temperature
probe stabilizes.
2. To perform temperature calibration, you must be in the pH
measurement mode.
3. Press MODE key to switch to the pH measurement mode if you are
in the mV or ion measurement modes.
4. Press CAL/MEAS key to enter pH calibration mode.
5. Press MODE key again to switch to temperature calibration.
6. Press ¿ or À key to scroll to the correct temperature value
corresponding to the known solution temperature. The meter allows
a limit of
± 5 o
C variation (with 0.1
o
C resolution) of the input
reading, and of the original displayed reading.
7. Once you selected the correct temperature, press ENTER key to
confirm. The meter automatically returns to the pH measurement
mode.
