Dear Customer, Thank you for choosing a HANNA instruments® product. Please read this instruction manual carefully before using the instrument. This manual will provide you with all the necessary information for the correct use of the instrument, as well as a precise idea of its versatility in a wide range of applications. If you need additional technical information, do not hesitate to e-mail us at tech@hannainst.com directives.
The log-on-demand function is activated by simply pressing one button, while for automatic logging, the user can select a time interval from 1 to 180 minutes. All logged data can be transferred to a PC by placing the instrument on the HI 9200 infrared interface, connected to the computer serial port. The connection is handled with the HI 92000 Windows® compatible software from HANNA instruments®. HI 98810 accepts one temperature probe while HI 98840 can be connected to 4 separate probes at the same time.

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.

Viewing logged data • Press CH/TIME (HI98840 only) or TEMP/TIME (HI98810 only) to view data of the selected sample. Data will be displayed in the following order: channel 1 temperature reading channel 2 temperature reading (HI 98840 only) channel 3 temperature reading (HI 98840 only) channel 4 temperature reading (HI 98840 only) date time • If CH/TIME or TEMP/TIME is pressed when the time is displayed, the LCD will pass to the next Sample number.
TAKING TEMPERATURE MEASUREMENTS HI 98810 - HI 98840 PRINTING / LOGGING FUNCTIONS To prepare the instrument for use, choose the most appropriate temperature probe(s) for your application (see accessories) and connect it (them) to the connector(s) located on the top of the instrument. All the probes have been precalibrated at the factory and no calibration is needed. 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.
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.
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 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 time, fixed at 1 year, has expired.
MEMORY ORGANIZATION HI 98810 - HI 98840 only PRINTER MAINTENANCE TO CHANGE THE INK CARTRIDGE Logged data are stored in the internal EEPROM and are retained even if batteries and external power are disconnected. When printouts become faint, it might be necessary to change the ink cartridge. Contact your Hanna authorized center.
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.
