PRELIMINARY EXAMINATION
GENERAL DESCRIPTION
HI8314
is an hand-held pH/ mV/ temperature meter designed
to be rugged, easy-to-use, reliable and practical.
It is ideal for education and for measurements on the field.
The pH, mV and temperature ranges are easily selected using
the rubber keyboard on the front panel.
Calibration procedure is very simple with clear help messages
displayed on LCD and adjustments are easily made with two
trimmers on the front panel.
The built-in temperature sensor in the pH electrode allows
automatic temperature compensation of pH readings.
Moreover,
HI8314
features a low battery indicator that alerts
the user when the battery needs to be replaced.

BATTERY REPLACEMENT
This meter is powered by a 9V alkaline battery.
When ‘’
BATT
’’ tag is displayed blinking a
low battery condition is indicated. When the
low battery indication appears, only a few
hours of working time are left. It is recommended to replace
the battery.
When the battery level is too low to ensure reliable measure-
ments, the meter turns off. It is recommended to replace the
battery immediately. Battery replacement must only take place
in a nonhazardous area using a 9V alkaline battery.
Unscrew the three screws on the rear of the meter, remove the
battery compartment cover and replace the 9V battery with a
new one, while observing the correct polarity.
Make sure the battery contacts are tight and secure before
replacing the cover.
