User manual HANNA INSTRUMENTS HI 143

[. . . ] This instrument is in compliance with the EMC Directive 89/ 336/EEC and Low Voltage Directive 73/23/EEC for electrical equipments, and with the EN 12830 guidelines for temperature data loggers as follows: - Suitability: S (Storage), T (Transport) - Location: C (Food storage and distribution systems) - Accuracy class: 1 - Measuring range: -30 to 70°C (-22 to 158°F) GENERAL DESCRIPTION HI 143 is a temperature data logger with internal NTC sensor. The user interacts with the logger, programming the device or downloading logged data, through a serial or USB port on a PC. The Windows® compatible application software supports the communication between the logger and the PC through a transmitter (HI 143001 with RS232 or HI 143002 with USB connector). The main features of the HI 143 thermologger include: · Logging start through PC, button pressed or at set time · Selectable sampling interval, from 1 minute to 24 hours · Up to 4000 logged samples · Selectable measure unit, °C or °F · Min/max measured values are stored and displayed · Programmable high and low alarms · Non-volatile storage of logging parameters and data · Battery level indicator on display · Security password · IP 65 protection SPECIFICATIONS Range -30. 0 to 70. 0ºC / -22. 0 to 158. 0ºF Resolution 0. 1°C / 0. 1°F Accuracy ±0. 4°C (-20 to 60°C); ±0. 6°C (outside) ±0. 7°F (-4 to 140°F); ±1. 1°F (outside) Typical EMC Dev.

"LOG DONE": Logging completed 4. Maximum and Minimum logged values IST143 12/05 OPERATIONAL GUIDE INITIAL OPERATION The logger is supplied complete with a CR2032 lithium battery. Open the battery comparment cover on the rear of the logger (see "Battery Replacement" section for details), insert the battery with the + sign facing up and tight back the compartment cover. The display will show the "PC" message to indicate that the logger needs to be programmed through a PC. STARTUP In order to communicate with the logger, the application software must be installed on your PC. Connect the HI 143001 or HI 143002 communication cradle to your computer through an available RS232 or USB port, and place the HI 143 on the cradle. WALL INSTALLATION The logger is supplied complete with wall cradle and lock (mounting materials as screws and dowels are not included). If the starting type was set to "at time", then the logger will automatically start logging at the programmed time. BUTTON FUNCTIONS Pressing the logger button will give different outputs depending on the logger status. · If the logger is in "WAIT TO LOG" condition, then pressing the button will cycle through current measurement, high and low alarm thresholds. Position the wall cradle at the desired location and fix it to the wall with proper screws. Insert the logger into the cradle and secure it with the supplied lock. BATTERY REPLACEMENT Each time the battery is installed, the logger enters in reset status and displays the "PC" message. Then it starts calculate the remaining battery life and displays the level through a 4-tag indicator. When the last tag (empty battery) starts blinking, the battery level is below 5%. It is recommended to change the battery with a new one. Battery replacement must only take place in a safe area and using the appropriate battery type (CR2032 3V lithium battery). Note: It is recommended to use a new battery for replacement, otherwise the battery level indication could be not reliable. When the battery needs to be replaced, open the battery compartment cover on the rear of the logger using a small coin. Turn counter-clockwise to open. · If the logger is in "LOG" or "LOG DONE" condition, then pressing the button will cycle through current measurement, maximum and minimum recorded values. DATA TRANSFER TO PC If you keep the button pressed, after 2 seconds the display will show alternatively (toggle every 2 seconds) the high and low alarm thresholds. [. . . ] If the starting type was set to "PC", then the "START" key will become active. If the starting type was set to "button", then the logger display will indicate that the logger button has to be pressed to start logging. Keep the button pressed for about 3 seconds. Insert the new battery with the + sign facing up, tight back the compartment cover and program the instrument. Note: Dispose of the lithium (Li) battery according to local regulations. Notes: · If an alarm threshold has not been set, then the logger will display the "diS" (disabled) message. [. . . ]
