GENERAL DESCRIPTION

HI 141 series of temperature data loggers are provided with
either one or two channels, and an optional LCD. The user
interacts with the logger, setting data acquisition parameters
or downloading logged data, through a RS232 serial port on
a Windows® PC. The HI 141000 Windows® application soft­ware supports the communication between the logger and the
PC through the HI 141001 Infrared Transmitter.

The main features of the HI 141 thermologgers include:

• One or two channels, with internal or external sensor;

• 16000 samples (for 1 channel models) or
8000 samples/channel (for 2 channels models);

• Logging interval from 1 second to 24 hours;

• Storing of temperature at logging interval, or min or
max temperature between logging intervals;

• Logging delay start up to 199 hours, and magnetic start
through magnetic key provided with the thermologger;

• Programmable high and low alarms;

• Non-volatile storage of logging parameters and data in
EEPROM;

• BEPS (Battery Error Prevention System);

• Security Password and lot serial number;

• Optional LCD with status, temperature and information
display;

• IP67 waterproof casing.
The expected life is about 4 years at 1 minute measuring and
logging intervals.
All HI 141 thermologgers are factory calibrated.

The optional LCD is divided into 3 areas: the status on the top,
the temperature readout in the middle, and useful information
at the bottom.

Recommendations for users

Before using these products, make sure that they are entirely suitable for the environment in which
they are used. Operation of these instruments in residential areas could cause unacceptable interfer­ences to radio and TV equipments, requiring the operator to take all necessary steps to correct
interferences. Any variation introduced by the user to the supplied equipment may degrade the
instruments’ EMC performance. To avoid damages or burns, do not perform any measurement in
microwave ovens.

IST141R2 05/05

Several models are available, as shown in the following table:

The information shown on the bottom is user-selectable, and
can include the current number of samples, the samples
beyond alarm limits, the min and max temperature, and the
high and low alarm thresholds.

In order to communicate with the

HI 141 thermologger, the
HI 141000 application software

must be installed on your PC.
This is done by inserting the first
floppy disk in the driver and
running Setup.exe.

Connect the HI 141001 Infrared
Transmitter to your computer
through an available RS232 port.

Place the HI 141 on the trans­mitter, taking care to align the
ribs on the logger with the slots
on the transmitter

Run HI 141000 software and
refer to the on-line help for any
further information about setting
the parameters of the logger,
acquiring logged data, etc.

BATTERY REPLACEMENT

Battery replacement must only take place in a non hazardous
area using the appropriate battery type (3.6V Lithium AA
battery).

When the battery needs to be
replaced, simply remove the four
screws on the rear cover of the
logger and replace the battery
with a new one paying attention
to the correct polarity. Replace the
cover and tighten the four screws.

When battery is replaced, both LEDs will turn on, and the Red
LED will then turn off followed by the Green LED. This indicates
that a proper reset of the logger has been done. Should this
not occur, please reinstall the battery.

For loggers with LCD, the LCD will also light up for about 1
second, showing all segments.

Note: Dispose of the Lithium (Li) battery according to local

regulations.
