OPERA
TIONAL GUIDE
• pH reading with the selected resolution.
• Temperature reading in the selected unit (°C or °F).
• Electrode condition during the calibration day.
• The buffers used in last pH calibration (if feature is enabled in
SETUP
).
• Battery level indicator.
• Available functional keys.
In order to take more accurate pH measurements, make sure that the instrument is calibrated (see
page 11 for calibration details).
It is recommended that the electrode is always kept moist 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.
On the pH screen are displayed:
TEMPERATURE MEASUREMENTS
For
HI98167
the temperature sensor is connected through DIN socket.
Note: The temperature can be displayed in Celsius degrees (
º
C) or in Fahrenheit degrees
(
º
F) (see SETUP for details, page 23).
BACKLIGHT FEATURE
The instrument is provided with a Backlight feature, which can be easily toggled on and off through
the keyboard by pressing
LIGHT
.
Note: The backlight automatically shuts off after a set period (see SETUP for details,
