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).

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

Alternatively, connect a 12 Vdc voltage adapter to the power adapter plug on the top of the instrument.

To prepare the instrument for use, choose the most appropriate temperature probe(s) for your application (see "Accessories" section for a complete list) and connect it (them) to the connector(s) on the top of the instrument.

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

To switch the meter on, press the ON/OFF key. The batteries charge status or "LINE" message (if external power adapter is connected) will be displayed on the LCD for a few seconds.

ON/OFF

The meter is now ready to operate.

To maximize battery life, the meter is automatically switched off after a user selectable period of non-use (this feature is enabled and set to 5 minutes by default; it can be disabled or changed through setup code #40).

If in logging mode, after the period of non-use, the meter will continue to monitor the temperature periodically at the end of every logging interval. Only the "LOG" indication will be displayed.

While storing data in memory, during the sleep mode, the reading will appear briefly on the LCD.

To reactivate the display press the ON/OFF key.

Note: When the use of an alternate function (FNC, CFM and LOT

INFO) is requested, press and hold the ALT key first and then the second key.

(*) Tables from NIST Monograph 175 revised to ITS-90 are used

SETUP MODE

Setup can be used to view data regarding instrument status (e.g. battery charge) or GLP data (e.g. calibration date) or to view or print the logged data. It also allows the user to change the meter parameters (e.g. time) and to gain access to stored data.

• To enter this mode ensure the meter is

not logging and then press the ALT and FNC keys.

• The scrolling message "Insert the function code or press "ALT" -

"FNC" to escape" in the upper LCD and the indication "F 00" with the first digit blinking in the lower LCD will be displayed.

PASSWORD PROTECTION

Setting of the GLP parameters (calibration alarm time-out, instrument ID code, time and date) can be password protected. If password is set to a value different from 0000 (factory setting), the user will be asked to enter the password.

• Select the desired GLP parameter code.

• Enter the password by the arrow keys.

• Press the ALT and CFM keys to confirm.

• If password is wrong the meter will return to the function selection mode without any warning message.

• If password is correct, the meter provides access to the parameter.

• Enter the first digit of the code of the parameter you want to set

using the  or  key and pass to the next digit with . The second digit will start blinking.

• Enter the second digit using the  or  key.

• Press ALT and CFM to confirm the code.

• If the entered code doesn't exist the "Err" message will be displayed for a few seconds and then the message "Insert the function code or press ALT - FNC to escape" will recommence scrolling in the upper LCD.

PARAMETERS SETTING

• Once the parameter code has been entered, the appropriate message will scroll across the LCD for a few seconds.

• The current value of the selected parameter on the upper LCD and the parameter code on the lower LCD will be displayed. The first digit will blink if the parameter can assume continuous values. All the digits will blink if the parameter can assume only a fixed set of values.

• Enter the new value using the arrow keys.

• Press ALT and CFM to confirm the value.

series as explained in detail in the following.

In HI 98801 and HI 98804 only.

In HI 98701 and HI 98704 only.

The meter automatically checks for entered time/date accuracy as follows:

0≤hh≤23; 0≤mm≤59; 01≤dd≤28/29/30/31; 1≤MM≤12; 1998≤YYYY≤2097.

To change the password, the correct code must be entered first. If the password has been forgotten, the password protected features are no longer accessible; in this case contact your nearest Hanna Service Center.

Some of the most important functions are explained below in a step by step sequence.

TO SCAN LOGGED DATA (HI98801 and HI98804 only)

COD. 00 - Lot data Printing / Scrolling

• Select the code 00.

• The message "Lot data Printing" will scroll twice across LCD.

• The upper LCD will then display L 00 with the 00 blinking.

• Set the desired lot by the arrow keys. L00 is the lot of data of the "log on demand" and L 01 to L 16 are the lots of the "timed log".

• Press the ALT and CFM keys to confirm the lot number.

• If the lot doesn't contain data, the "no data" message will scroll across the LCD twice and the meter will return to setup mode.

• If the lot contains one or more data the LCD will display the sample number in its upper part and Sn in the lower part.

Note: In the L 00 lot (log on demand) the sample number will be

displayed with 3 digits (001).

• Select the sample number to scan by the arrow keys.

Printing logged data

• Press ALT and CFM to print logged data.

• If the selected sample number is invalid (equal to 0 or bigger than the number of samples), the "Err" message will be displayed for a few seconds.

• If the sample number is correct, the samples starting from the selected one to the last sample of the lot will be printed. To stop printing before the last sample is reached, press and hold the ALT and PAPER keys until the printer stops.

• During printout the LCD will display the sample number being printed at that moment. If printout is stopped the LCD will show
