HI 98810 and HI 98840 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 infrared transmitter
(ensuring that the two infrared LEDs are placed on top of each other).
The memory content can then be downloaded to your PC through an
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 HI 9200 infrared 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 very easy with the
HI 92000 Windows
® compatible software 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.

OTHER FEATURES
LCD BACKLIGHT
The backlit LCD allows the user to operate even in dark environments.
This feature can be enabled and 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 instru-
ment, the backlight is not automatically enabled.
Note: When the "LOBAT" message appears on LCD, it is not possible
to enable the backlight. If the user attempts to enable the
backlight in low battery condition, the meter will display 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 discon-
nected.
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 calibra-
tion. 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. 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.
GLP AND RS232 (HI 98810 and HI 98840 only)
GLP data (ID code & last calibration date) can be retrieved from a PC
through RS232 communication feature (see "Data transfer to PC").
