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 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. 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 (HI 98801 and HI 98804 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").

OTHER FEATURES

LCD BACKLIGHT
The backlit LCD allows an easy use of the instrument even in dark
environments. This feature can be enabled/disabled pressing the ALT
and LIGHT keys. The LCD backlight can be disabled in order to save
power, and it is automatically disabled when a low battery level is
detected.
Note: When an external power supply is applied to the instrument,
the backlight is not automatically enabled.
Note: When "LOBAT" appears on the LCD it is not possible to enable
backlight. If the user attempts to enable the LCD backlight in
low battery condition, the meter displays 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.

DATA TRANSFER TO PC

HI 98801 - HI 98804 only
HI 98801 and HI 98804 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 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 a serial
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 dis-
plays 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 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 now much easier
with the HI 92000 Windows ® compatible application software offered
by HANNA instruments ® .
HI 92000 allows you to use the powerful capabilities of most spread

sheet programs (e.g. Excel , Lotus 1-2-3
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.
