PRINTER MAINTENANCE
CHANGING THE INK CARTRIDGE
When printouts become faint, it might be
necessary to change the ink cartridge. Con-
tact your dealer or the nearest HANNA Office
for technical service.
INSERTING PAPER ROLL
HI 9141 and HI 91410 use plain 38 mm wide
paper rolls. To insert a new roll gently pull out
the printer cover.
Take out the used paper cylinder.
Insert the paper edge in the printer slot and
feed the paper through by pressing the PA-
PER key.
Allow about 5 cm (2") of paper to exit from
the printer and then replace the cover.
MEMORY ORGANIZATION
(HI 91410 ONLY)
Capacity: 8000 data samples, divided into
16 pages.
Data capacity per page:
500 data samples.
Each time a new logging period starts, it
automatically starts from a new page.
If “LOGGING” is still on, and the available
page is “0” the meter will overwrite the first
LOT DATA in the existing meter memory.
During logging the meter automatically re-
turns to the oldest page in the memory and if
it contains data, it will overwrite it. In this
case the first log will not correspond to the
oldest set of data.
It is recommended to periodically “clean” the
memory. Save the data on your PC if you
need to keep a record and then disconnect
the batteries for about 1 minute. Afterwards,
remember to re-set the date, time, altitude
and salinity.
WARNING
If batteries need to be replaced and data is
not to be lost, power the meter through a
12Vdc adapter before proceeding with battery
replacement.
Once batteries have been changed, the ex-
ternal power supply can be disconnect without
losing the previously memorized data.
