PRELIMINARY EXAMINATION
GENERAL DESCRIPTION
HI142 series is a family of temperature dataloggers especially
designed for applications in supermarket shelves and ware-
houses. It is possible to monitor continuously and simultaneously
the temperature condition in up to 31 locations.
They can all be wired through RS485 to the HI504903 GSM
supervisor or to a local PC, allowing data downloading
without removing the loggers from their sites.
Moreover, with HI504903 GSM supervisor it is possible to
receive SMS when an alarm occurs (low/high temperature,
low battery level, etc.) or upon user request.
The user can interact with the meters through a PC using the
HI92140 Windows
® compatible software for setting High and
Low alarm thresholds, logging interval, logging delay start,
alarm mask time, lot ID, etc.
The logger can memorize up to 7600 samples (i.e. stops
when memory is full) and can also work in a cyclic way (i.e.
old data are replaced by new samples when memory is full).
In case of power failure, an internal battery assures a
working time of at least 1 week.
The status of the logger is indicated by the 2 front LEDs
(green and red) as follows:

OPERATIONAL GUIDE
For connecting the HI142 loggers with the HI504903 GSM
supervisor, please refer to the HI504903 instruction manual.
It is possible to connect up to 31 units within the same
RS485 network with a wires total length up to 1 km.
After connection to the GSM supervisor, the user can program
and real-time monitor the loggers and also download the
data from a PC with the HI92140 software installed. Refer to
the on-line-help for further details.
The PC can be locally connected to the HI504903 supervisor
with a serial cable or can call the HI504903 from remote
location through a modem connection.
Before starting any operation, activate
each logger by pulling the nylon strip
in the indicated direction.
Simply hang the logger out of the
site to be monitored and insert the
temperature probe (1.5 m cable).
