INITIAL 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 a K-type thermocouple
temperature probe to the connector located on the top of the
instrument.
To switch the HI92701 and the HI92704 on,
press the ON/OFF key.
To switch the HI92801 and the HI92804 on,
press the TEMP key.
Choose the most appropriate temperature probe(s) for your applica-
tion (see page 30) and connect it (them) to the meter.
HI 92701 and HI 92801 have a single probe connection.
HI 92704 and HI 92804 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 is not connected to the instrument, the
meter will display and print "----" to alert the user.
Thisalso indicatesthe possibilityof abroken probecable. Thechannel
is displayed with "CH" and the number of channel (four channels
versionsonly).
Note: To ensure accurate readings it is recommended that the
temperature probes be connected to consecutive channels be-
ginning 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.

WORKING SAMPLE (HI 92801 AND HI 92804 ONLY)
The following is a step by step procedure of a typical monitoring
situation where we have assumed that you have already inserted the
batteries and set the date and time correctly.
It is an example of a meter used to monitor and store every 2
minutes. The meter will log 10 samples but print only 3, display the
data contained in sample number 1 and print samples 5 through
10.

HI 92801 and HI 92804 provide infrared
emitting circuitry. Set the meter to the TIME
mode and place your data-logger on a
HI9200 Infrared Transmitter (ensuring that
the two infrared LEDs are placed on top of
each other). The memory can be downloaded
to your PC through the HI9200's RS232
port.
During the data transfer the instrument dis-
plays the message "r 232".
Using the HI 9200 Infrared Transmitter, all recorded data can be fed
to your Personal Computer for easy reproduction, storage or elabora-
tionwithoutthe interferenceof cables orcords betweenthemeter and
the transmitter.
Data transmission from the instrument to the PC is now much easier
with the new HI92000 Windows®compatible application software
offered by Hanna Instruments.
User friendly, HI92000offers a variety of features and has an on line
help feature to support you throughout all situations.
HI92000 allows you to use the powerful means of the most diffused
spread sheet programs (e.g. Excel©, Lotus 1-2-3©). Simply run your
favorite spread sheet and open the file downloaded by HI92000. It
is then possible to make any elaboration available with your software
(e.g. graphics, statistic analysis).
To install HI92000 you need a 3.5" drive and few minutes to follow
the instructions conveniently printed on the disk's label.

HI 92701, HI 92704, HI 92801 and HI 92804 are factory pro-
grammed to automatically diagnose a fault. This is displayed with
error codes on the LCD.
Errorcodes:
PEr0, PEr1, PEr2 = Short circuit on the system, the meter should be
returned for repair (see Warranty section).
PEr3 = Printer mechanism fault - repair needed (see Warranty
section).
PEr4 = Printer clutch jammed - reset the printer (see page 27).
PEr9 = Printer jammed - reset the printer (see page 27).

16,000 data samples, divided into 16 pages.
Data capacity per page:
1000 data samples with 1 channel monitored;
500datasampleswith2channelsmonitored(fourchannelsversionsonly);
250datasampleswith3or4channelsmonitored (fourchannels versionsonly).
Each time a new logging period starts, it automatically starts from a
new page.
If “LOGGING” is still on, and the available page is “0” the meter will
overwrite the first LOT DATA in the existing memory. During logging
the meter automatically returns to the oldest page in the memory
and if it contains data, it will overwrite. In this case the first log will
not correspond to the oldest set of data
It is recommended to periodically “clean” the memory. Save the data
in a PC if you need to keep a record and then disconnect the batteries
for about 1 minute. If you do this, remember to set the date and
time, once the batteries have been connected again.
ATTENTION
Data is stored in memory until the batteries are removed.
To replace batteries without loosing data, plug the adapter in and
proceed with battery replacement as described below. Only once
batteries have been replaced it is possible to unplug the adapter
without loosing the stored data.

If "LO BAT" appears on the display, it is an
indication that the batteries are running down.
If it appears during printing, approximately
200 printouts can still be made before the
batteries are exhausted. When there is only sufficient power for 100
printouts, the "LO BAT" sign is displayed continuously on the LCD.
Battery replacement must only take place in a non-hazardous area
using alkaline AA type 1.5V batteries.
In order to replace run down batteries, simply remove the two screws
on the rear cover of the instrument and replace the four 1.5V AA
batteries with new alkaline ones, paying attention to the correct
polarity.
A 12VDC power source can also be used to power the unit (see
Accessories on page 33).
Note: The instrument uses the following configuration.
It is recommended to use Hanna Instruments HI 710005 and
HI 710006 voltage adapters that use the proper polarity configura-
tion.

HI 92701, HI 92704, HI 92801 and HI 92804 can also be used
with other adapters supplying a 12VDC output. In this case,
remember to check the correct polarity of your adapter before
connecting it to the meter.
WARNING: With HI 92801 and HI 92804, if the external power
supply or batteries are disconnected, all stored data will
be erased. Always employ external power to the instru-
ment when changing the batteries to prevent loss of
data.
All Hanna thermometers have been accurately precalibrated at the
factory.
However, as a general rule, it is recommended to have all thermom-
eters recalibrated at least once a year.
For an accurate annual recalibration, contact your dealer or the
nearest Hanna Customer Service Center.
