[. . . ] These instruments are in compliance with the SPECIFICATIONS Model HI142AH HI142BH HI142CH HI142DH HI142EH HI142FH HI142GH HI142HH Range Resolution Accuracy ±1. 5°C ±0. 5°C ±0. 5°C ±0. 5°C ±0. 3°C ±0. 3°C ±0. 3°C ±2°C LED INDICATORS The status of the logger is indicated by the 2 front LEDs (green and red) as follows: 1. Green LED always ON: the meter has been reset and requires new setting of the parameters. Green LED flashes once every 4": the meter is logging. Green LED flashes twice every 4": the meter is waiting for a delayed logging start. [. . . ] 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. 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).
