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.

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. PASSWORD PROTECTION Setting of the GLP parameters (calibration alarm time-out, instrument ID code, time and date) can be password protected.

the last printed sample number. It is then possible to select another sample. • Press the ALT and FNC keys to return to setup mode. Viewing logged data • Press CH/TIME (HI98804 only) or TEMP/TIME (HI98801 only) to view data of the selected sample.
TAKING TEMPERATURE MEASUREMENTS TEMPERATURE CALIBRATION PROCEDURE (for technical personnel only) 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.
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.
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.
TO RETRIEVE LOGGED DATA TO STOP PRINTING Logged data can be viewed on LCD or printed. To view or print logged data see "TO SCAN LOGGED DATA" in the "SETUP MODE" paragraph. The logging meters also allow the downloading of logged data to PC. To download data to PC see "DATA TRANSFER TO PC" paragraph. 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.
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.
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.
BATTERY REPLACEMENT 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.
