GENERAL DESCRIPTION

This series of HANNA instruments® portable thermocouple thermom­eters with built-in printer and microprocessor technology, provides
accurate temperature measurements and data record.

The meters can support K, J or T thermocouple probes, one for models
HI 98701 and HI 98801, up to four for HI 98704 and HI 98804.

The thermocouple type is user selectable.
The meters are equipped with an easy-to-read LCD with backlight

feature for comfortable reading even in dark environments.
The meters provide a controlled access to calibration and GLP settings

through a password protection method.
An alarm time-out is available to alert the user if too much time has

elapsed since the last calibration and that re-calibration may be
required.

To prolong battery life, the backlight and printing features are
disabled when the batteries are getting low; "LOBAT" indication is
displayed on LCD to warn the user of this condition. However, the
meter continues to measure correctly even when the low battery
indication is displayed. The Battery Error Preventing System (BEPS)
automatically switches the meter off when the batteries are too weak
to support proper function.

The meters are equipped with an internal lithium battery that
powers the clock circuit even in the absence of power supplies.

For long term field and lab applications, these instruments can be
connected to a 12 Vdc adapter.

HI 98801 and HI 98804 can store the measurements in memory at
a user selectable interval from 1 to 180 minutes. This information can
be retrieved at a later time and also printed.

HI 98801 and HI 98804 also allow the transfer of stored data to a
computer via the HI 9200 infrared transmitter connected to the
computer RS232 port.

Each meter can also be uniquely identified by the user by assigning
an ID code.

HANNA instruments® produces a wide range of K-type thermocouple
probes that can be used with these thermometers for many applica­tions (HI 766 series, see "Accessories" section).

TAKING TEMPERATURE MEASUREMENTS

To prepare the instrument for use, choose the most appropriate
temperature probe for your application (see "Accessories" section) and
connect it to the instrument.
The factory default thermocouple type is K, represented with the "dF"
indication. If needed, select a different type (J and T types also
available) through setup code #70.
With the meter facing you, channel #1 is the first connector on the
top left hand side.
Press the ON/OFF key to power on the instrument, and insert the
probe in the sample to be tested and allow the reading to stabilize.
The temperature is displayed on the upper
LCD. The lower LCD shows the selected chan­nel number (HI 98704 and HI 98804 only).
The meter selects channel 1 as default. Press
CH/TIME (HI 98704 and HI 98804) or TEMP/
TIME (HI 98701 and HI 98801) to view the
reading of the other channels, the cold junc­tion temperature, date and time in the
following order:

• channel 2 temperature reading (4-channel versions only)

• channel 3 temperature reading (4-channel versions only)

• channel 4 temperature reading (4-channel versions only)

• cold junction temperature reading ("C J" appears in the lower LCD)

• date

• time
Pressing CH/TIME or TEMP/TIME again, the meter returns to channel
1 temperature reading.
If the reading is out of range or the probe is
not connected to a channel, the LCD will
display dashes in place of the reading.

Note: To choose between "°C " and "°F" unit, enter the setup code 71.
Note: The meter is factory calibrated.

After 1 year since last thermocouple
calibration the "DATE" symbol starts
blinking on the LCD to warn the user
that a recalibration is suggested to
maintain the meter accuracy.
Contact the nearest HANNA service center for an accurate
recalibration of your thermometer.

TEMPERATURE CALIBRATION PROCEDURE

(for technical personnel only)

The meter is factory calibrated. However, as a general rule, it is
recommended to have all thermometers recalibrated at least once a
year. It is recommended that recalibration is performed by authorized
technical personnel only to assure the accuracy of the instrument.
Contact the nearest HANNA service center for an accurate annual
recalibration.

Both thermocouple inputs and cold junction can be calibrated.
A two-point calibration at 0.000 mV and 41.269 mV has to be

performed in order to store the new thermocouple calibration data in
memory. Cold junction calibration is at one point only, corresponding
to the environment temperature.

COLD JUNCTION CALIBRATION

1. Press CH/TIME or TEMP/TIME until the cold junction temperature
reading is displayed.

2. Press ALT, CFM and PAPER simultaneously while the meter is not
printing nor logging to enter calibration mode.

3. User is prompted to enter password if it has been set to a value
different from 0000, otherwise skip to step 6.

4. Enter the password using the arrow keys.

5. Press ALT and CFM to confirm the password or CH/TIME or TEMP/
TIME to exit.

6. If password is correct or not set, the meter
will display "25.0°C" (or "77.0°F"), with
the "2" (or "7") blinking, on the upper
LCD and "C CJ" on its lower part; if
wrong, it will return to measurement mode without any message.

7. Enter the actual cold junction temperature (the environment tem­perature measured with a reference thermometer) using the arrow
keys (temperature must be between 0 and 50 °C).

8. When the "S" symbol blinks in the lower
LCD, the reading is stable and calibration
can be confirmed pressing ALT and CFM.

9. The LCD will display CALC for a few seconds and then the meter
returns to normal operational mode.

1514

THERMOCOUPLE CALIBRATION

1. With a mV simulator, input 0.000 mV at channel #1 of the meter.

2. Ensure the meter is not displaying the cold junction temperature
and press ALT, CFM and PAPER simultaneously while the meter is
not printing nor logging to enter calibration mode.

3. User is prompted to enter password if it has been set to a value
different from 0000, otherwise skip to step 6.

4. Enter the password using the arrow keys.

5. Press ALT and CFM to confirm or CH/TIME or TEMP/TIME to exit.

6. If password is correct or not set, the meter
will display "0°C" on the upper LCD and
"C 0" on its lower part; if wrong, it will
return to measurement mode without any
message.

7. When the "S" symbol blinks in the lower
LCD, the reading is stable and calibration
can be confirmed pressing ALT and CFM.

8. The LCD will display CALC for a few seconds.

9. The second calibration point "1000°C"
will be displayed on the upper LCD and
"C 0" on its lower part.

10. Input 41.269 mV at channel #1 of the meter.

11. When the "S" symbol blinks in the lower
LCD, the reading is stable and calibration
can be confirmed pressing ALT and CFM.

12. "CALC" is displayed on the upper LCD for a few seconds and then
the meter returns to normal operational mode.

Note: Even though only channel #1 is used during calibration, all

the channels and all the thermocouple types are calibrated.

Note: If a wrong input is connected or channel #1 is left open, when

confirming the calibration point the LCD will display "Err".

Note: To escape before ending the calibration procedure press CH/TIME

or TEMP/TIME.

Note: When connecting a mV simulator to the meter use two wires of the

same material of the simulator terminals to avoid undesired ther­mocouple junctions that could alter the mV input of the meter.

Note: Avoid touching the meter connectors if possible and wait about 15

minutes for temperature stabilization after connections before pro­ceeding with the calibration steps.

HI 98801 - HI 98804

PRINTING / LOGGING FUNCTIONS

Two different modes to print / log data are available:

1. Timed logging; samples are stored and printed (if print function is

active) at fixed time intervals. Data are stored in the lots 01 to 16.

2. Log on demand; samples are stored and printed (if print function

is active) when the LOG key is pressed. Data are stored in the lot

00. It's possible to perform the Log on demand either in normal
mode or in Timed logging mode.

It is possible to switch from logging without printing to logging with
printing in two ways:

• set the function code 02 to "On" to enable printing, to "Off" to
disable printing

• press ALT and PAPER to toggle between printer enabled and
printer disabled while in Timed logging.

Note: In timed logging mode, channels with no probe connected are

not logged nor printed. If all the channels are disconnected,
the message "no connected probe" will scroll across the LCD.

Note: cold junction temperature is not logged nor printed.

TIMED LOGGING MODE

To start Timed logging, press ALT and LOG.
The lot number will be displayed for a few
seconds then the LOG symbol will appear on
LCD and if printer is enabled a first set of
data will be printed. The "LOG" symbol will
be fixed if printer is enabled and will blink if
printer is disabled.

The printout provides the following information:

a - Lot number
b - Logging interval
c - Date (only for the first printed

sample of the lot or of the day)
d - Sample number
e - Time
f - Readings ("----" means out of range).

Note: If no keys are pressed, the meter enters standby mode to

prolong the battery life and only the "LOG" indication will be

visible on LCD. While logging, during the sleep mode, the last

1716

logged reading will appear briefly on the LCD. To reactivate the
LCD press ON/OFF.

TO STOP LOGGING

In order to stop the recording mode, press
ALT and LOG keys (press ON/OFF first, if
meter is in sleep mode).

A last printout reporting the number of logged
samples (e.g. S.00009) will be produced if
printer is enabled.

Notes:

• It is recommended to use the adapter during logging in printing
mode, especially when many printouts are going to be taken.

• Before proceeding with logging with printing, 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. If this happens, data will continue to be stored in memory,
and it is always possible to print the data at a later time through
setup code 00.

• It is possible to insert a new paper roll during logging session.

• Once in the logging mode, the interval cannot be changed. Exit
the logging mode first (pressing the ALT and LOG keys) to set a
new interval.

• If the LOG key is pressed while in logging with printing mode, a
printout is produced without affecting the running sample number
and the value is stored in Log on demand area.

LOW BATTERY CONDITION

Printout is automatically disabled when battery charge weakens. The
last message "Stop log" will be printed and data will continue to be
stored in memory with the LOG and LOBAT
symbols blinking on LCD. If the user attempts
to enable the printer while in low battery
condition the message "bAtt" will appear for
a few seconds on the LCD.

Note: When an external adapter or new batteries are connected, the

printing must be manually enabled in order to return to logging
with printing mode.

LOG ON DEMAND

In measuring or Timed log mode, press LOG to store
the current reading. The LCD will display "Stor" and

the value will be stored in the lot 00 (log on demand data area). If
the print function is enabled, a printout is also produced providing the
following information:

a - Date
b - Sample number
c - Time
d - Readings ("----" means out of

range or probe not connected)

Note: When the Log on demand data area is full and the LOG key is

pressed, the sample will not be stored and the LCD will display
"FULL". In this case it is necessary to delete the Log on demand
data to proceed.

TO VIEW LOGGING INFORMATION

If the ALT and LOT INFO keys are pressed during logging, the meter
displays for a few seconds the current lot and the number of logged
samples. The meter then returns to normal operational mode auto­matically.

If ALT and LOT INFO are pressed while the meter is not logging, the
last logged lot in the lower LCD and the number of logged samples in
the upper LCD are displayed. It is then possible to scroll through the
following lot information with the  key:

• lot starting date (dd.mm)

• lot starting year

• lot starting time (hh.mm)

• lot logging interval

• logged channels (HI 98804 only)
By pressing the  key again, the meter displays the number of

logged samples again.
When the number of logged samples is displayed, it possible to pass

to another lot with the  and  keys. Press  to view the older
lots or  to view the more recent ones.

If  is pressed when the last lot is displayed, the meter displays the
lot 00 (log on demand). By pressing the  key again, the meter will
pass to the oldest lot.

Note For lot 00, only the number of samples will be displayed.
To exit from the logging info viewing mode press ALT and LOT INFO

again or CH/TIME (HI98804 only) or TEMP/TIME (HI98801 only).

PRINTING FUNCTIONS

Two different modes to print data are available:

1. Timed printing; samples are printed at fixed time intervals. Data
lots from 01 to 16 are available.

2. Print on demand; samples are printed when the LOG key is
pressed. It's possible to perform the print on demand either in
normal mode or in Timed printing mode.

Note: In timed printing mode, channels with no probe connected are

not printed. If all the channels are disconnected, the message
"no connected probe" will scroll across the LCD.

Note: cold junction temperature is not printed.

TIMED PRINTING MODE

To start Timed printing, press ALT and LOG.
The lot number will be displayed for a few
seconds then the LOG symbol will appear on
LCD and a first set of data will be printed.

The printout provides the following informa­tion:

a - Lot number
b - Logging interval
c - Date (only for the first printed

sample of the lot or of the day)
d - Sample number
e - Time
f - Readings ("----" means out of range).

Note: If no keys are pressed, the meter enters standby mode to

prolong the battery life and only the "LOG" indication will be

visible on LCD. While timed printing during the sleep mode, the

last printed reading will appear briefly on the LCD. To reacti-

vate the LCD press ON/OFF.

TO STOP PRINTING

In order to stop the recording mode, press
ALT and LOG keys (press ON/OFF first, if
meter is in sleep mode).

A last printout reporting the number of printed
samples (e.g. S.00009) will be produced.

Notes:

• It is recommended to use the adapter during printing mode,
especially when many printouts are going to be taken.

• Before proceeding with printing, 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 printing session.

• Once in the timed printing mode, the interval cannot be changed.
Exit the timed printing mode first (pressing the ALT and LOG keys)
to set a new interval.

• If the LOG key is pressed while in timed printing mode, a printout
is produced without affecting the running sample number.

LOW BATTERY CONDITION

Printing is automatically interrupted when
battery charge weakens. The last message
"Stop log" will be printed and the LOBAT
symbol will blink on LCD.

Note: When an external adapter or new batteries are connected, a

new printing session must be manually restarted.

LOG ON DEMAND

In measuring or timed printing mode, press LOG to
print the current readings. The printout provides the
following information:

a - Date
b - Sample number
c - Time
d - Readings ("----" means out of

range or probe not connected)

Note: If the user attempts to print while in low battery condition the

message "bAtt" will appear for a few seconds on the LCD.

Note: It is possible to reset the sample number of the print on

demand to 001 (see "TO RESET PRINTING SAMPLE NUMBER"
in "SETUP MODE" paragraph).

GOOD LABORATORY PRACTICE (GLP)

GLP is a set of functions that allows the storage or retrieval (when
necessary) of data regarding the maintenance and status of the meter.

LAST CALIBRATION DATE

Last calibration date is stored automatically after a successful calibra­tion. The last calibration date can be displayed through the setup
code #10 (see "Setup Mode" section for details).

CALIBRATION ALARM TIME-OUT

Every time it is turned on, the meter checks if the time-out, fixed at
1 year, has expired. It is possible to enable/disable this feature
through setup code #11. The default value is "0n".

If the time has expired, the message "Cal
date" scrolls across the LCD. The "DATE"
symbol will blink to remind to the user to
perform a new calibration soon.

Note: The alarm time-out is based on thermocouple calibration only.

GLP AND RS232 (HI 98801 and HI 98804 only)

GLP data (ID code and last calibration date) can be retrieved from a PC
through the RS232 communication feature (see "Data transfer to PC").

OTHER FEATURES

LCD BACKLIGHT

The backlit LCD allows an easy use of the instrument even in dark
environments. This feature can be enabled/disabled pressing the ALT
and LIGHT keys. The LCD backlight can be disabled in order to save
power, and it is automatically disabled when a low battery level is
detected.
Note: When an external power supply is applied to the instrument,

the backlight is not automatically enabled.

Note: When "LOBAT" appears on the LCD it is not possible to enable

backlight. If the user attempts to enable the LCD backlight in
low battery condition, the meter displays the "batt" message.

Real Time Clock (RTC)

The instrument has an internal Real Time Clock (RTC) circuit with a
backup lithium battery. This allows the meter to update time and date
even when both batteries and external power adapter are discon­nected.

DATA TRANSFER TO PC

HI 98801 - HI 98804 only

HI 98801 and HI 98804 can transfer data to a computer, through
the HI 9200 infrared interface and a serial port on the PC.

Ensure there isn't any logging process active.
Press CH/TIME or TEMP/TIME to set the meter to time or date mode

and simply place the meter on a HI 9200 transmitter (ensuring that
the two infrared LEDs are placed on top of each other) and the
memory content can then be downloaded to your PC through a serial
port. Just ensure that baud rate on instrument (setup code #50)
and on PC downloading program are set to the same value.

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

To stop communication, press CH/TIME or TEMP/TIME to display the
temperature reading or take the meter out of the transmitter when
it's not displaying "r232".

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

Data transmission from the instrument to the PC is now much easier
with the HI 92000 Windows® compatible application software offered
by HANNA instruments®.

HI 92000 allows you to use the powerful capabilities of most spread
sheet programs (e.g. Excel©, Lotus 1-2-3©). Simply open your file
downloaded by HI 92000 from your spread sheet program and then
it is possible to make any elaboration available with your software
(e.g. graphics, statistic analysis). HI 92000 offers a variety of features
and has an on line help to support you throughout any situation.

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

MEMORY ORGANIZATION

HI 98801 - HI 98804 only

Logged data are stored in the internal EEPROM and are retained even
if batteries and external power are disconnected.

MEMORY CAPACITY

• 14000 data samples divided into 16 lots (lots 01 to 16)

• 9999 data samples maximum for a single channel

• 300 data samples for the Log on demand (lot 00).

TIMED LOG (lots 01 to 16)

Each time a new logging period starts, it automatically starts from the
next available lot. If the last lot was the 16th, the new logging period
restarts from lot 01 overwriting previously logged data.

When Timed logging memory is full, the meter overwrites the oldest
lot data progressively reducing the old lots. In this case the starting
time, date and the dimension of the old lot are updated.

Note: The oldest lot data are erased without any warning message.
Note: Timed logging memory can be entirely erased through the

setup code 06.

If the meter is powered only by the external power supply and there is
a temporary power black out during logging, when power returns, the
logging continues normally if no samples have been lost, otherwise
the current lot is ended and a new lot starts. If printer is enabled, the
"...Stop..." message will be printed. In any case, during scrolling the
former lot will be preceded by the "Interrupted Lot" message and the
latter by "Continuation Lot" to indicate the interruption.

LOG ON DEMAND (Lot 00)

When Log on demand data area is full the meter shows the "FULL"
message to warn the user that the data are not stored in memory.
Erase the memory area through setup code 05 to continue logging
data on demand.

PRINTER MAINTENANCE

TO CHANGE THE INK CARTRIDGE

When printouts become faint, it might be necessary to change the ink
cartridge. Contact your Hanna authorized center.

TO INSERT THE PAPER ROLL

The meters use plain
paper rolls 38 mm
width. To insert a new
roll open the paper
cover pulling it gently
and take the cylinder
away.

Insert the paper edge in
the printer slot and feed
the printer by pressing the
PAPER key.

Allow about 5 cm (2") of paper to exit
from the printer and replace the paper
cover.

FAULT CONDITIONS

The printing/logging thermometers are factory programmed to auto­matically diagnose a fault and to display error codes on the LCD.

PRINTER ERROR

Whenever a printer fault condition is detected, the printer stops and
the message "Printer error" scrolls across the upper LCD with the error
code (see below) fixed on the secondary one.

1 = Motor locked
2 = Printer clutch jammed
3 = Selection lever fault

I2C BUS ERROR

In case of an I2C bus fatal error due for example to a defective
EEPROM or RTC, the message "Serial bus error" keeps scrolling across
LCD from right to left indefinitely. Meter should be returned for repair
(see warranty section).

K-TYPE THERMOCOUPLE PROBES

When the batteries are inserted and no power adapter is connected,
the meter can recognize different batteries charge levels.

1. Fully charged batteries. The backlight and printer can be

enabled.

2. Weakening batteries - "LOBAT" symbol blinks on LCD. The

backlight and printer are automatically disabled and it is not
possible to enable them until new batteries are inserted or an
external power adapter is connected.

3. Weak batteries - "LOBAT" symbol stays still on lower LCD.

Backlight and printer are disabled and meter can work for about
20 hours. If in Timed logging mode with the power down
function enabled this time can be longer.

4. Dead batteries - LCD shuts off. The instrument stops working to

avoid erroneous readings.

Note It is not possible to activate backlight and printer when the

instrument is in a low battery condition. If the user attempts to
enable these functions without replac­ing the batteries or connecting the
external power adapter, the meter will
show "batt" on LCD.

Battery replacement must only take place in a non hazardous area
using 1.5V alkaline AA type 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 ones, paying atten­tion to the correct polarity.

A 12VDC power adapter can also be used to
power the unit (see the accessories para­graph).

Note: The instrument uses the following configuration.

The HANNA HI 710005 or HI 710006 voltage adapters are recom­mended, because they use the proper polarity configuration.

However, the meters can be used with other adapters. In this case,
remember to check the correct polarity of the adapter before connect­ing it to the meter.
