It is recommended to purchase a HANNA
instruments
® voltage adapter (HI 710005 or
HI 710006) that uses the proper polarity con-
figuration.

can also be used with other adapters.
In this case, check the correct polarity of the
adapter before connecting it to the meter.
WARNING: With HI 955301 and HI 955302 , if
the external power supply or bat-
teries are disconnected, all stored
data will be erased. Always apply
external power to the instrument
before changing the batteries to
prevent data from being lost.

LOBAT
The "LO BAT" indication is
displayed to warn the user that
the batteries are running down.
If the warning appears during printing, it means
that 200 printouts can still be made. When
the battery level can only support 100 print-
outs, "LO BAT" is continuously displayed.
Battery replacement must only take place in
a safe area and using the battery type specified
in this instruction manual.
To replace batteries,
simply remove the two
screws on the rear
cover and replace all
four 1.5V AA batter-
ies with new ones,
while paying attention
to the polarity.
A 12 Vdc power source can also be used to
power the unit.
Note: The instrument uses the following con-
figuration.
