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);

GENERAL DESCRIPTION

HI 141 series is a family of temperature data loggers 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.

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

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.

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.

START UP

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 re-
fer 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.
