GENERAL DESCRIPTIONGENERAL DESCRIPTION
GENERAL DESCRIPTION
GENERAL DESCRIPTIONGENERAL DESCRIPTION
The Hanna Instruments portable NTC thermometers with built-in printers are microprocessor-based and enable you to accurately measure
temperature and record data.
The instruments housing is made of rugged and lightweight material
making it truly portable.
The meters come equipped with an easy-to-read LCD with backlight
feature for comfortable reading even in dark environments.
A user friendly interface provides clear messages regarding errors,
functions and more.
The GLP features provide a guarantee of data consistency.
Measurements can be performed with lab-grade precision in the field as
well as in the laboratory.
An alarm time-out is available to alert the user if too much time has
elapsed since the last calibration and that re-calibration may be
required.
The meters provide a GLP settings through a password protection
method.
The Battery Error Preventing System (BEPS) recognizes batteries levels
as they become weaker.

To prolong battery life, the backlight and printing features are disabled when the batteries are getting low; "LOBAT" indication is displayed
on LCD to warn the user of this condition. 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 12VDC adapter.

PRINTING / LOGGING FUNCTIONS
PRINTING / LOGGING FUNCTIONSPRINTING / LOGGING FUNCTIONS
Two different modes to print / log data are available:
1. Timed logging; samples are stored and printed (if print function is
active) at fixed time intervals. Data are stored in the lots 01 to 16.
2. Log on demand; samples are stored and printed (if print function
is active) when the LOG key is pressed. Data are stored in the lot
00. It's possible to perform the Log on demand either in normal
mode or in Timed logging mode.
It is possible to switch from logging without printing to logging with
printing in two ways:
• set the function code 03 to "On" to enable printing, to "Off" to
disable printing
• press ALT and PAPER to toggle between printer enabled and
printer disabled while in Timed logging.
TIMED LOGGING MODE
To start Timed logging, press ALT and LOG.
The lot number will be displayed for a few
seconds then the LOG symbol will appear on
LCD and if printer is enabled a first set of
data will be printed. The "LOG" symbol will
be fixed if printer is enabled and will blink if
printer is disabled.
The printout provides the following information:
a - Lot number
b - Logging interval
c - Date (only for the first printed
sample of the lot or of the day)
d - Sample number
e - Time
f - Readings ("----" means out of range).
Note: channels with no probe connected are not logged nor printed.
If no keys are pressed, the meter enters standby mode to prolong the
battery life and only the "LOG" indication will be visible on LCD. While
logging, during the sleep mode, the last logged reading will appear
briefly on the LCD. To reactivate the LCD press ON/OFF.
1514
TO STOP LOGGING
In order to stop the recording mode, press
ALT and LOG keys (press ON/OFF first, if
meter is in sleep mode).
A last printout reporting the number of logged
samples (e.g. S.00009) will be produced if
printer is enabled.
Notes:
• It is recommended to use the adapter during logging in printing
mode, especially when many printouts are going to be taken.
• Before proceeding with logging with printing, make sure there is
enough paper for your measurements. When the paper is finished
the meter will not advise the operator and the printouts could be
lost. If this happens, data will continue to be stored in memory,
and it is always possible to print the data at a later time through
setup code 00.
• It is possible to insert a new paper roll during logging session.
• Once in the logging mode, the interval cannot be changed. Exit
the logging mode first (pressing the ALT and LOG keys) to set a
new interval.
• If the LOG key is pressed while in logging with printing mode, a
printout is produced without affecting the running sample number
and the value is stored in Log on demand area.
LOW BATTERY CONDITION
Printout is automatically disabled when batteries charge weakens. The
last message "Stop log" will be printed and
data will continue to be stored in memory
with the LOG and LOBAT symbols blinking on
LCD. If the user attempts to enable the printer
while in low battery condition the message
"bAtt" will appear for a few seconds on the
LCD.
Note: When an external adapter or new batteries are connected, the
printing must be manually enabled in order to return to logging
with printing mode.
LOG ON DEMAND
In measuring or Timed log mode, press LOG to store
the current reading. The LCD will display "Stor" and
the value will be stored in the lot 00 (log on de-
mand data area). If the print function is enabled, a printout is also
produced providing the following information:
a - Date
b - Sample number
c - Time
d - Readings ("----" means out of
range or probe not connected)
Note: When the Log on demand data area is full and the LOG key is
pressed, the sample will not be stored and the LCD will display
"FULL". In this case it is necessary to delete the Log on demand
data to proceed.
TO VIEW LOGGING INFORMATION
If the ALT and LOT INFO keys are pressed during logging, the meter
displays for a few seconds the current lot and the number of logged
samples. The meter then returns to normal operational mode automatically.
If ALT and LOT INFO are pressed while the meter is not logging, the
last logged lot in the lower LCD and the number of logged samples in
the upper LCD are displayed. It is then possible to scroll through the
following lot information with the Æ key:
• lot starting date (dd.mm)
• lot starting year
• lot starting time (hh.mm)
• lot logging interval
• logged channels (HI 98840 only)
By pressing the Æ key again, the meter displays the number of
logged samples again.
When the number of logged samples is displayed, it possible to pass
to another lot with the Ç and È keys. Press È to view the older
lots or Ç to view the more recent ones.
If Ç is pressed when the last lot is displayed, the meter displays the
lot 00 (log on demand). By pressing the Ç key again, the meter will
pass to the oldest lot.

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" paragraph).
CALIBRATION ALARM TIME-OUT
The meter checks if the time-out time, fixed at 1 year, has expired
every time it is turned on. 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 (HI98810 and HI98840 only)
GLP data (ID code and last calibration date) can be retrieved from a PC
through the RS232 communication feature (see "Data transfer to PC").

LCD BACKLIGHT
The LCD can be illuminated to allow the user to see the readings even
in dark environments. This feature can be enabled/disabled pressing
the ALT and LIGHT keys. If the LCD backlight feature is enabled, the
LCD remains illuminated until the feature is 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 instrument,
the backlight is not automatically enabled.
Note: When LOBAT appears on LCD it is not possible to enable
backlight. If the user attempts to enable the LCD backlight in
low battery condition, the meter will show "batt" on LCD.
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.

HI98810 and HI98840 contain infrared transmitting circuitry.
Ensure there isn't any logging process active.
Press CH/TIME or TEMP/TIME to set the meter to time or date mode
and simply place your data-logger on a HI9200 Infrared Transmitter
(ensuring that the two infrared LEDs are placed on top of each other)
and the memory content can then be downloaded to your PC through
the HI9200's RS232 port. Just ensure that baud rate on instrument
(setup code 50) and on PC downloading program are set to the same
value.
During the data transfer the instrument displays the message "r 232".
To stop communication, press CH/TIME or TEMP/TIME to display the
temperature reading or take the meter out of the transmitter when it's
not displaying "r232".
Using the HI9200 Infrared Transmitter, all recorded data can be fed
to your Personal Computer 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 now much easier
with new HI92000 Windows® compatible application software offered
by Hanna Instruments.
HI92000 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 HI92000 from your spread sheet program and then it
is possible to make any elaboration available with your software (e.g.
graphics, statistic analysis).
User friendly, HI92000 offers a variety of features and has an on line
help to support you throughout any situation.
To install HI92000 you need a 3.5" drive and a few minutes to follow
the instructions conveniently printed on the disk label.

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.

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.
FAULT CONDITIONSFAULT CONDITIONS
FAULT CONDITIONS
FAULT CONDITIONSFAULT CONDITIONS
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).

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 replacing 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 12VDC power adapter can also be used to
power the unit (see the accessories paragraph).
