TO CHANGE THE INK CARTRIDGE
When printouts become faint, it might be necessary to change the ink
cartridge. Contact your Hanna authorized center.
TO INSERT THE PAPER ROLL
The meters use plain
paper rolls 38 mm
width. To insert a new
roll open the paper
cover pulling it gently
and take the cylinder
away.
Insert the paper edge in
the printer slot and feed
the printer by pressing the
PAPER key.
Allow about 5 cm (2") of paper to exit
from the printer and replace the paper
cover.

Logged data are stored in the internal EEPROM and are retained even
if batteries and external power are disconnected.
MEMORY CAPACITY
• 14000 data samples divided into 16 lots (lots 01 to 16)
• 9999 data samples maximum for a single channel
• 300 data samples for the Log on demand (lot 00).
TIMED LOG (lots 01 to 16)
Each time a new logging period starts, it automatically starts from the
next available lot. If the last lot was the 16th, the new logging period
restarts from lot 01 overwriting previously logged data.
When Timed logging memory is full, the meter overwrites the oldest
lot data progressively reducing the old lots. In this case the starting
time, date and the dimension of the old lot are updated.
Note: The oldest lot data are erased without any warning message.
Note: Timed logging memory can be entirely erased through the
setup code 06.
If the meter is powered only by the external power supply and there is
a temporary power black out during logging, when power returns, the
logging continues normally if no samples have been lost, otherwise
the current lot is ended and a new lot starts. If printer is enabled, the
"...Stop..." message will be printed. In any case, during scrolling the
former lot will be preceded by the "Interrupted Lot" message and the
latter by "Continuation Lot" to indicate the interruption.
LOG ON DEMAND (Lot 00)
When Log on demand data area is full the meter shows the "FULL"
message to warn the user that the data are not stored in memory.
Erase the memory area through setup code 05 to continue logging
data on demand.
The printing/logging thermometers are factory programmed to auto-
matically diagnose a fault and to display error codes on the LCD.
PRINTER ERROR
Whenever a printer fault condition is detected, the printer stops and
the message "Printer error" scrolls across the upper LCD with the error
code (see below) fixed on the secondary one.
1 = Motor locked
2 = Printer clutch jammed
3 = Selection lever fault

C BUS ERROR
In case of an I
2
C bus fatal error due for example to a defective
EEPROM or RTC, the message "Serial bus error" keeps scrolling across
LCD from right to left indefinitely. Meter should be returned for repair
(see warranty section).
