Note: Save all packing material until you are sure that the instrument functions correctly. All defective items must be returned in their original packaging together with the supplied accessories.

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

The thermocouple type is user selectable to best suit the temperature range of your application. K, J and T thermocouple types can be selected.

The instruments housing is made of rugged and lightweight material making it truly portable.

The meters come equipped with an easy-to-read LCD with backlight feature for comfortable reading even in dark environments.

A user friendly interface provides clear messages regarding errors, functions and more.

The GLP features provide a guarantee of data consistency.

Measurements can be performed with lab-grade precision in the field as well as in the laboratory.

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.

The meters provide a controlled access to calibration and GLP settings through a password protection method.

The Battery Error Preventing System (BEPS) recognizes batteries levels as they become weaker.

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 meter automatically switches itself 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 meters can be connected to a 12VDC adapter.

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

17

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

18 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.

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 reactivate the LCD press ON/OFF.

20

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).

21

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 setup code 10

(see "SETUP MODE" paragraph).

CALIBRATION ALARM TIME-OUT

The meter checks if the time-out time, fixed at 1 year, has expired every time it is turned on. 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 (HI98801 and HI98804 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").

LCD BACKLIGHT

The LCD can be illuminated to allow the user to see the readings even in dark environments. This feature can be enabled/disabled pressing the ALT and LIGHT keys. If the LCD backlight feature is enabled, the

LCD remains illuminated until the feature is disabled pressing the ALT and LIGHT keys. The LCD backlight can be disabled in order to save power and it is automatically disabled when battery charge weakens.

Note: When an external power supply is connected to the instrument, the backlight is not automatically enabled.

Note: When LOBAT appears on LCD it is not possible to enable backlight. If the user attempts to enable the LCD backlight in low battery condition, the meter will show "batt" on LCD.

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.

22

DATA TRANSFER TO PC

HI 98801 - HI

HI98801 and HI98804 contain infrared transmitting circuitry.

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 your data-logger on a HI9200 Infrared 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 the HI9200's RS232 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 HI9200 Infrared Transmitter, all recorded data can be fed to your Personal Computer 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 new HI92000 Windows

®

compatible application software offered by Hanna Instruments.

HI92000 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 HI92000 from your spread sheet program and then it is possible to make any elaboration available with your software (e.g.

graphics, statistic analysis).

User friendly, HI92000 offers a variety of features and has an on line help to support you throughout any situation.

To install HI92000 you need a 3.5" drive and a few minutes to follow the instructions conveniently printed on the disk label.

MEMORY ORGANIZATION

HI

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.

24

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.

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

I

2

C BUS ERROR

In case of an I

2

C 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).

25

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.

+ -

It is recommendable to purchase the Hanna HI710005 and HI710006 voltage adapters that use the proper polarity configuration.

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