GENERAL DESCRIPTION

PRELIMINARY EXAMINATION

For printing and measuring temperature in
the higher ranges without having to compro­mise high resolution, HANNA instruments
has developed the HI 955201 single channel
and the HI 955202 dual channel, 4-wire Pt100
printing thermometers.

These thermometers have a resolution of 0.1°C
in the range of -200.0 to 850.0°C. A built-in
printer makes it possible to obtain a hard­copy of your temperature measurements taken
on 1 or 2 channels, instantly or at determin­able intervals. The low-power printer uses plain
paper that will not fade over time and is
widely available.

For extended time measurements, the meters
can be powered with 12 Vdc.

These meters are calibrated against certified
standards.

HI 955301 and HI 955302 combine the high
resolution and extended temperature range of
the HI 955201 and HI 955202 models with
extensive logging capabilities and an infrared
data transfer system. In addition to supplying
the user with instant printouts of date, time
and temperature, they also provide data log­ging facilities that store data for transfer to a
computer system for retrieval and/or printing
at a later date.

HI 955301 accepts one temperature probe
while HI 955302 can take 2 separate Pt100
probes.

The sophisticated software allocates up to
16000 temperature readings to maximize avail­able space, regardless of the number of chan­nels in use.

HANNA instruments® offers a wide variety of
optional 4-wire Pt100 HI 768 temperature
probes to fit any application needs.

Remove the instrument from the packing mate­rial and examine it carefully to make sure that no

®

damage has occurred during shipping. If there is
any damage, notify your dealer.

Each meter is supplied complete with:

• 5 paper rolls

• Batteries (4 x 1.5V AA alkaline)

• Rugged carrying case

• Instruction manual

Note: Save all packing material until you are

sure that the instrument functions cor­rectly. All defective items must be re­turned in its original packaging together
with the supplied accessories.

INITIAL PREPARATION

Each meter is supplied complete with batter­ies. Remove the back cover, unwrap the bat­teries and install them while paying attention
to the correct polarity (see "Battery Replace­ment" section).

To prepare the thermometer for use, connect
a Pt100 temperature probe to the connector
on the top of the instrument.

To save battery life, the display is auto­matically switched off after 5 minutes of
non-use. However, if in logging/recording
mode, the meter will continue to monitor
the temperature.

To activate the display, press the ON/OFF
(HI 955201 and HI 955202) or TEMP
(HI 955301 and H I 955302) key.

To switch the HI 955201

HI955201 and HI 955301 are provided with a
single probe connection, while HI955202 and
HI955302 feature two probe connectors.

Looking at the display side, channel #1 is the
first connector on the top left hand side.

If no temperature probe is
connected to the thermom­eter, it will display and print
"----" to alert the user.

• It is recommended to power the instru­ment with an external supply during re­cording mode, especially when many print­outs are going to be taken.

• Before proceeding with recording, make
sure there is enough paper for your mea­surements. When the paper is finished
the meter will not advise the operator and
the printouts could be lost.

• It is possible to insert a new paper roll
during recording session (see "Printer
Maintenance" section).

• If the PRINT key is pressed while still in
recording mode, a printout is produced
without affecting the running number.

• Once in recording mode, the printing inter­val cannot be changed. First exit the re­cording mode by pressing ON/OFF, then
set the new interval.

WORKING SAMPLE
(HI 955301 and HI 955302 only)

The following step by step description refers
to a typical monitoring situation, after insert­ing the batteries and setting date and time.

Suppose that the meter is used to monitor
and store every 2 minutes. The meter will log
10 samples but print only 3, display the data
contained in sample #1 and print samples 5
through 10.

Example:

Step 1 - Setting a 2-minute interval

Press ALT and TIME keys twice. The time
will be displayed together with the blinking
printing/logging interval.

Press the UP or DOWN key until a blinking
"2" appears.

Note: Before proceeding with printing, make

sure there is enough paper for the data
to be printed. When the paper is fin­ished the meter will not advise the
operator and printouts could be lost.
If this happens, stop
the printer by press­ing ALT and PAPER

DATA TRANSFER TO PC

HI 955301 and HI 955302 feature infrared

emitting circuitry.
Set the meter to TIME mode

and place it on a HI 9200
infrared transmitter while en­suring that the infrared LEDs

of instrument and interface
match. The memory can be
downloaded to a PC through
an RS232 port.

During the data transfer the
instrument displays the mes­sage "r 232".

UP

DOWN

Press ALT and PRINT.
The meter will printout
samples # 5, 6, 7, 8, 9
and 10 consecutively.

PRINT

ALT

Using the HI 9200 infrared transmitter, all
recorded data can be fed to your PC for easy
reproduction, storage or elaboration without
the interference of cables or cords between
the meter and the transmitter.

Data transmission from the instrument to the
PC is handled with the HI 92000 Windows
compatible software by HANNA instruments®.

HI 92000 offers a variety of features to help

HI 92000 allows you to use the powerful
means of the most common spread sheet
programs (e.g. Excel©, Lotus 1-2-3©).

Simply run your favorite spread sheet and
open the file downloaded by HI 92000. It will
then possible to make any elaboration avail­able with your software (e.g. graphics, statis­tic analysis).

To install HI 92000, you need a 3.5" drive and
a few minutes to follow the instructions con­veniently printed on the disk's label.

FAULT FUNCTIONS

HI 955201, HI 955202, HI 955301 and HI
955302 are factory programmed to automati-

cally diagnose a fault and display the corre­sponding error code.

Error codes:
PEr0, PEr1, PEr2 = Short circuit on the

system, the meter should be returned
for repair. Contact your dealer.

PEr 3 = Printer mechanism fault - repair

needed. Contact your dealer.

PEr 4 = Printer clutch jammed - reset the

printer. See "Printer Maintenance"
section.

PEr 9 = Printer jammed - reset the printer.

See "Printer Maintenance" section.

MEMORY ORGANIZATION

Capacity: 16000 data samples, divided into

16 pages.

Data capacity per page:

1000 data samples with 1 chan­nel monitored;
500 data samples with 2 chan­nels monitored (HI 955302 only).

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 meter memory.
During logging the meter automatically re­turns to the oldest page in the memory over­writing existing data (if any). 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. Remember to
set date and time again, once the batteries
have been reinserted.

ATTENTION

Data are stored into memory until batteries
are removed.

If battery replacement is needed and data are
not to be lost, power the instrument through
the 12 Vdc adapter and then proceed with
battery replacement. Only after new batteries
have been installed, the adapter can be un­plugged without losing stored data.

If the warning appears during printing, it means
that 200 printouts can still be made. When
the battery level can only support 100 print­outs, "LO BAT" is continuously displayed.

Battery replacement must only take place in
a safe area and using the battery type specified
in this instruction manual.

To replace batteries,
simply remove the two

while paying attention
to the polarity.

It is recommended to purchase a HANNA
instruments® voltage adapter (HI 710005 or
HI 710006) that uses the proper polarity con­figuration.
HI955201, HI955202, HI955301 and HI955302
can also be used with other adapters.
In this case, check the correct polarity of the
adapter before connecting it to the meter.

WARNING: With HI 955301 and HI 955302 , if

the external power supply or bat­teries are disconnected, all stored
data will be erased. Always apply
external power to the instrument
before changing the batteries to
prevent data from being lost.
