down an extra decimal point
is displayed on the Liquid
Crystal Display to warn the
user.
Battery replacement must only take place in
a non hazardous area using the battery types
specified in this instruction manual (see
page 46).
In order to replace run down
batteries, simply remove the
two screws on the rear cover
of the instrument and replace
the four 1.5V AA batteries with
new ones, paying attention to
the correct polarity.

It is recommendable to purchase the Hanna
HI710005 and HI710006 voltage adapters that
use the proper polarity configuration.
Anyway, HI 9624, HI 9625, HI 96240 and
HI 96250 can be used with other adapters. In
this case, remember to check the correct
polarity of your adapter before connecting it
to the meter.
