HI 98810 accepts one temperature probe while HI 98840 can be
connected to 4 separate probes at the same time.
All models use the HI 762 series of thermistor probes by HANNA
instruments®, and can be powered with batteries or with a 12 Vdc
supply.
To prolong battery life, the backlight and printing features are disabled when the batteries are getting low; the "LOBAT" indication is
displayed on LCD to warn the user. However, the meter continues to
measure correctly even when the low battery indication is displayed.
The meter automatically switches itself off when the batteries are too
weak to support proper function.
The meters are equipped with an internal lithium battery that powers the clock circuit even in the absence of power supplies.
For long term field and lab applications, these meters can be connected
to a 12 Vdc adapter.
Each meter can also be uniquely identified by the user by assigning
an ID code.

it's not displaying "r232".
Using the HI 9200 infrared transmitter, all recorded data can be fed
to your PC for easy reproduction, storage or elaboration without the
need of cables between the meter and the transmitter.
Data transmission from the instrument to the PC is very easy with the
HI 92000 Windows® compatible software by HANNA instruments®.
HI 92000 allows you to use the powerful capabilities of most spread
sheet programs (e.g. Excel©, Lotus 1-2-3©). Simply open your file
downloaded by HI 92000 from your spread sheet program and then
it is possible to make any elaboration available with your software
(e.g. graphics, statistic analysis).
HI 92000 offers a variety of features and has an on line help to
support you throughout any situation.
To install HI 92000 you need a 3.5" drive and a few minutes to
follow the instructions conveniently printed on the disk label.

OTHER FEATURES
LCD BACKLIGHT
The backlit LCD allows the user to operate even in dark environments.
This feature can be enabled and disabled pressing the ALT and
LIGHT keys. The LCD backlight can be disabled in order to save power
and it is automatically disabled when battery charge weakens.
Note: When an external power supply is connected to the instru-
ment, the backlight is not automatically enabled.
Note: When the "LOBAT" message appears on LCD, it is not possible
to enable the backlight. If the user attempts to enable the
backlight in low battery condition, the meter will display the
"batt" message.
Real Time Clock (RTC)
The instrument has an internal Real Time Clock (RTC) circuit with a
backup lithium battery. This allows the meter to update time and date
even when both batteries and external power adapter are disconnected.
GOOD LABORATORY PRACTICE (GLP)
GLP is a set of functions that allows the storage or retrieval (when
necessary) of data regarding the maintenance and status of the meter.
LAST CALIBRATION DATE
Last calibration date is stored automatically after a successful calibration. The last calibration date can be displayed through setup code
#10 (see "Setup Mode" section for details).
CALIBRATION ALARM TIME-OUT
Every time it is turned on, the meter checks if the time-out time, fixed
at 1 year, has expired. It is possible to enable/disable this feature
through setup code #11. The default value is "0n".
If the time has expired, the message "Cal
date" scrolls across the LCD. The "DATE"
symbol will blink to remind to the user to
perform a new calibration soon.
GLP AND RS232 (HI 98810 and HI 98840 only)
GLP data (ID code & last calibration date) can be retrieved from a PC
through RS232 communication feature (see "Data transfer to PC").

PRINTER MAINTENANCE
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.
MEMORY ORGANIZATION
HI 98810 - HI 98840 only
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 automatically 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
I2C BUS ERROR
In case of an I2C 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).

TEMPERATURE PROBES
When the batteries are inserted and no power adapter is connected,
the meter can recognize different batteries charge levels.
1. Fully charged batteries. The backlight and printer can be
enabled.
2. Weakening batteries - "LOBAT" symbol blinks on LCD. The
backlight and printer are automatically disabled and it is not
possible to enable them until new batteries are inserted or an
external power adapter is connected.
3. Weak batteries - "LOBAT" symbol stays still on lower LCD.
Backlight and printer are disabled and meter can work for about
20 hours. If in Timed logging mode with the power down
function enabled this time can be longer.
4. Dead batteries - LCD shuts off. The instrument stops working to
avoid erroneous readings.
Note It is not possible to activate backlight and printer when the
instrument is in a low battery condition. If the user attempts to
enable these functions without replac-
ing the batteries or connecting the
external power adapter, the meter will
show "batt" on LCD.
Battery replacement must only take place
in a non hazardous area using 1.5V alkaline AA type batteries.
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.
A 12 Vdc power adapter can also be used
to power the unit (see "Accessories").
Note: The instrument uses the following configuration.
The use of HANNA HI 710005 or HI 710006 voltage adapters with
the proper polarity configuration, is recommended.
However, the meters can be used with other adapters. In this case,
remember to check the correct polarity of the adapter before connecting it to the meter.
