GENERAL DESCRIPTION

The Hanna Instruments portable NTC Fast Tracker thermometer with
built-in printer enables you to accurately measure and record both
temperature and sample identification data.

The instrument housing is made of rugged and lightweight material
making it truly portable.

The meter comes 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.
The Sample Identification feature eliminates the necessity of manual

identification for different measurement results, reducing the human errors.
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 more than one year

has elapsed since the last calibration and that recalibration may be
required.

The meter provides GLP settings through a password protection method.
The Battery Error Preventing System (BEPS) recognizes batteries levels

as they become weaker to prevent erroneous readings.

3

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 meter is 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, this meter can be connected to
a 12VDC adapter.

HI 98811 has the capability to store the measurements in memory at
a user selectable interval from 1 to 180 minutes. This information can
be retrieved at a later time and also printed.

Each measurement/lot can be uniquely identified by assigning a
sample ID code obtained by reading from a Dallas i-Button® tag
(DS1990A, etc) suitable placed in the field.

HI 98811 also allows the transfer of stored data to a computer via
the HI9200 infrared transmitter connected to the computer RS232
port.

Each meter can also be uniquely identified by the user by assigning
an instrument ID code.

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 - while not in timed logging mode.

• press ALT and PAPER to toggle between printer enabled and
printer disabled while in Timed logging mode.

TIMED LOGGING MODE

To start Timed logging, press ALT and LOG.
"tAG" will be displayed on the upper part of

the LCD and "Id" on the lower part. For
Sample ID code reading an i-Button® tag
must be touched by the touch probe on the
back of the meter within a 20 second inter­val. If a tag is recognized the meter will beep
once and if the printing is disabled the last
six digits of the tag's code will be displayed on the LCD for a few seconds.

Tag reading can be skipped by pressing LOG (a null Sample ID will
be stored).

Note: Tag reading timeout - after 20 seconds left without reading any

tag, the logging operation will be aborted with a longer beep.

The lot number will be displayed for a few seconds, then the "LOG"
"INTV" symbols will appear on LCD and if
printer is enabled a first set of data will be
printed. The "LOG" "INTV" symbols 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

If no keys are pressed, the meter enters sleep mode to prolong the
battery life and only the "LOG" "INTV" symbols 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.

STOP LOGGING

In order to stop the recording mode, press
ALT and LOG (press ON/OFF first, if meter
is in sleep mode).

A last report containing the number of
logged samples (e.g. S.0009) will be printed
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 and 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 ALT and LOG) 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", "INTV"
and "LOBAT" symbols blinking on LCD. If the
user attempts to enable the printer while in

and if the printing is disabled the last six
digits of the tag's code will be displayed on the LCD for a few seconds.

Tag reading can be skipped by pressing LOG (a null Sample ID will
be stored).

Note: Tag reading timeout - after 20 seconds left without reading

any tag, the logging operation will be aborted.

The LCD will display "Stor" and the value will be stored in the lot 00
(log on demand data area). If the print function is enabled, a
printout is also produced providing the following information:

a - Sample ID
b - Date
c - Sample number
d - Time
e - Readings ("----" means out

of range or probe not connected)

Note: When the Log on demand data area is full (300 samples

stored) 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 free space.

VIEW LOGGING INFORMATION

If ALT and LOT INFO are pressed during logging, the meter displays
for a few seconds the current lot and the number of logged samples.
Then the meter returns to normal operational mode automatically.

If ALT and LOT INFO are pressed while the meter is not logging, the

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).

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 the user to
perform a new calibration as soon as possible.

GLP AND RS232

GLP data (instrument ID code and last calibration date) can be
retrieved from a PC through the RS232 communication feature (see
"Data transfer to PC").

OTHER FEATURES

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 by 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.

HI 9200'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 data transfer the instrument displays
the message "r 232".

To stop communication, press TEMP/TIME to display the temperature
reading or take the meter out of the transmitter when it's not
displaying "r232".

Using the HI 9200 Infrared Transmitter, all recorded data can be
uploaded 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 supported by the
HI 92000 Windows® compatible application software offered by
Hanna Instruments.

HI 92000 allows you to memorize in a database the downloaded data
from different instruments, for different periods of time and for different
reading locations. The records will contain the date and time, specific
reading, the place of reading and the logging way (Log on demand or
Auto logging). HI 92000 offers support for database data management
by applying different selection criteria: period of time, reading location,
logging way. With the results of selection it is possible to make graphics,
statistic analysis or to export data into Excel format file.

User friendly, HI 92000 offers a variety of features and has an online
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.

MEMORY ORGANIZATION

Logged data are stored in the internal EEPROM and are retained even
if batteries and external power are disconnected.

MEMORY CAPACITY

• 12900 data samples divided into 16 lots (lots 01 to 16)

• 9999 data samples maximum in one single lot

• 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 reducing progressively 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 blackout during logging, when power returns, the
logging continues normally if no sample has been lost, otherwise the
current lot is ended and a new lot starts with the same sample ID.
If the 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 data are not stored in memory. Erase
the memory area through setup code 05 to continue logging data on
demand.

PRINTER MAINTENANCE

CHANGE THE INK CARTRIDGE

When printouts become faint, it might be necessary to change the ink
cartridge. Contact your Hanna authorized center.

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 CONDITIONS

The printing/logging thermometer is 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
the LCD from right to left indefinitely. Meter should be returned for
repair (see warranty section).

BATTERY REPLACEMENT

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 the lower LCD.
Backlight and printer are disabled and the 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 take place only 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 sec­tion).

Note: The instrument uses the following configuration.

It is recommendable to purchase the Hanna HI 710005 and HI 710006
voltage adapters that use the proper polarity configuration.

However, the meters can be used with other adapters. In this case,
remember to check the correct polarity of your adapter before connecting
it to the meter.
