Hanna Instruments HI 9141 - Manual (Page 17)

When batteries become
weak, the "LO BAT" indica-
tion is displayed to warn the
user. If it blinks during printing, it means that
200 printouts can be made before the batter-
ies are exhausted. When there is only suffi-
cient power for 100 printouts, the "LO BAT"
indication is displayed continuously.
Battery replacement must only take place in
a safe area and using the battery type specified
in this instruction manual.
To replace the
batteries, simply
remove the two
screws on the
rear cover of the
instrument and
replace the four
1.5V AA batteries
with new ones,
while paying at-
tention to the cor-
rect polarity.
A 12 Vdc power source can also be used to
power the unit.
Note: The instrument uses the following con-
figuration.
It is recommended to use the HANNA
HI710005 or HI710006 voltage adapters with
the proper polarity configuration.

TO RESET THE PRINTER
Take off the battery
compartment cover
by removing the
screws on the back
of the meter.
Using a sharp pen-
cil press the black
reset button. This
will reset the print-
ing mechanism.
Before replacing the battery cover, investigate
likely cause of the printer jam (e.g. the paper
might be caught under the cover preventing
the paper from advancing).
Replace the battery cover and tighten the
screws.
