BATTERY REPLACEMENT
If "LO BAT" appears on the
display, it indicates that the
batteries are running down.
If it blinks during printing, it means that 200
printouts can be made before the batteries
are exhausted. When there is only sufficient
power for 100 printouts, the "LO BAT" sign is
displayed continuously on the LCD.
Battery replacement must only take place in
a non hazardous area using the battery types
specified in this instruction manual (see
page 35).
In order to replace
run down batteries,
simply remove the
two screws on the
rear cover of the in-
strument and re-
place the four 1.5V
AA batteries with
new ones, paying
attention to the cor-
rect polarity.
A 12VDC power
source can also be
used to power the
unit (see the Ac-
cessories section
page 35).
Note: The instrument uses the following con-
figuration.

It is recommendable to purchase Hanna In-
struments HI 710005 and HI710006 voltage
adapters that use the proper polarity configu-
ration.
HI9141 and HI 91410 can also be used with
other adapters. In this case, remember to
check the correct polarity of your adapter
before connecting it to the meter.
WARNING: In HI91410, if the external power
supply and batteries are discon-
nected, all stored data will be
erased. Always apply external
power supply to the instrument
when changing low batteries to
prevent data from being lost.
