GENERAL DESCRIPTION

The Hanna Instruments portable thermometers with built-in printers are microprocessor-based and enable you to accurately measure temperature and record data.

The instrument housing is made of rugged and lightweight material.

Equipped with a large, easy-to-read LCD, the units feature an extended battery life and a special design that enables results to be obtained even in humid, wet or dusty conditions. Measurements can be performed with labgrade precision in the field as well as in the laboratory without compromising accuracy. A 12VDC adapter can also be used to power the unit for extended use.

HI92810 and HI92840 have a capacity of 16,000 individual temperature readings with recording intervals selected by the user.

Using the HI9200 infrared transmitter, all the recorded data can be fed to a PC for easy reproduction, storage or elaboration without the interference of cables and cords between the meter and the receiver.

Other features include: on-board clock and date, user-selectable recording/logging intervals, automatic memorization of measured values (HI92810 and HI92840 only), use of pre-calibrated completely interchangeable probes, printing on plain paper, automatic shut-off capability, low battery warning and 2 year warranty.

Two versions are available:

HI 92710C, HI 92740C, HI 92810C and HI 92840C perform temperature readings in

degrees Centigrade;

HI 92710F, HI 92740F, HI 92810F and HI 92840F perform temperature readings in

degrees Fahrenheit.

INITIAL PREPARATIONINITIAL PREPARATION

INITIAL PREPARATION

INITIAL PREPARATIONINITIAL PREPARATION

Each meter is supplied complete with batteries. Remove the back cover, unwrap the batteries and install them while paying attention to the polarity.

To prepare the instrument for use, connect the temperature probe to the connector located on the top of the instrument.

To switch the HI 92710 and the HI 92740 "ON", press the ON/OFF key.

ON/OFF

To switch the HI 92810 and the HI 92840 "ON" press the TEMP key.

TEMP

Choose the most appropriate temperature probe(s) for your application (see page 35) and connect it (them) to the meter.

All the probes have been precalibrated at the factory and no calibration is needed.

HI 92710 and HI 92810 have a single probe connector.

HI 92740 and HI 92840 have four probe connectors.

With the meter facing you, channel #1 is the first connector on the top left hand side.

If the temperature probe or a calibration test plugs is not connected to the channel input, the meter will display and print "----" to alert the user.

°C

This also indicates the possibility of a broken probe cable. The channel is displayed with "CH" and the number of channel (four channels versions only).

Note: To ensure accurate readings it is rec-

ommended that the temperature probes be connected to consecutive channels beginning with channel #1. For example, if only one probe is to be used, it must be connected to channel #1. If 2, 3 or 4 probes are to be used, they must be connected to channels 1, 2, 3, and 4 in ascending order.

To maximize battery life, the display is automatically switched off after 5 minutes of nonuse. However, the meter will continue to monitor temperature (if in the logging mode) .
