Allow for the electrode to adjust and reading to stabilize (hourglass
symbol turns off).
On the pH screen are displayed:
• pH reading with the selected resolution.
• Temperature reading in the selected unit (ºC or ºF).
• Temperature compensation mode (MTC - manual, ATC - automatic).
While in MTC mode the indicate that the temperature can be
manually changed using ARROW keys.
• Electrode condition during the calibration day.
• The buffers used in last pH calibration (if feature is enabled in
SETUP).
• Available function keys.
In order to take more accurate pH measurements, make sure that the
instrument is calibrated (see page 19 for details).
It is recommended that the electrode is always kept wet and rinsed
thoroughly with the sample to be measured before use.
The pH reading is directly affected by temperature. For accurate pH
measurements, temperature must be taken into consideration. If the
sample temperature is different from the temperature at which the pH
electrode was kept, allow a few minutes to reach thermal equilibrium.
To use the instrument's Automatic Temperature Compensation feature,
submerse the temperature probe into the sample as close to the electrode
as possible and wait for a few seconds.
If manual temperature compensation (MTC) is desired, the
temperature probe must be disconnected from the instrument.
The display will show the last measured temperature reading, or the last
set temperature, with the “MTC” indication.
The “MTC” indication and the symbol light up on the LCD to indicate
that the instrument is in MTC mode and the ARROW keys can be used
to enter the desired temperature value.
Note: When in MTC mode the user can press and hold an ARROW key,
and the instrument will start incrementing/decrementing the
temperature value. The instrument keeps measuring and the
display is updated periodically.
