GENERAL DESCRIPTIONGENERAL DESCRIPTION
GENERAL DESCRIPTION
GENERAL DESCRIPTIONGENERAL DESCRIPTION
HI98240 is a portable printing and logging microprocessor-based pH/
ORP/temperature meter.
HI98230 is a portable printing and logging microprocessor-based pH/
temperature meter.
HI98230 and HI98240 are supplied with an exclusive HANNA
(smart) amplified pH/temperature electrode with DIN connector. The
electrode has an internal memory for storing calibration data.
All pH measurements are automatically compensated for temperature
(ATC). The instrument housing is made of rugged, lightweight material,
making it truly portable.
Five memorized buffers (4.01, 6.86, 7.01, 9.18 and 10.01pH) and
wrong buffer recognition technology make calibration simple and error
free. One or two-point calibration is possible.
The meters are also equipped with a stability indicator and backlight
feature for comfortable reading even in excessively dark environments.
A user friendly interface provides clear messages regarding errors,
functions and more.
The GLP features provide a guarantee of data consistency.
Measurements can be performed with lab-grade precision in the field as
well as in the laboratory.
32
An alarm time-out is available to alert the user if too much time has
elapsed since the last pH calibration and that re-calibration may be
required.
The meters provide a controlled access to calibration and GLP settings
through a password protection method.
The Battery Error Preventing System (BEPS) recognizes batteries levels
as they become weaker.
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 meter automatically switches itself 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 meters can be connected
to a 12VDC adapter.
When in logging mode, the meter stores 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.
HI98230 and HI98240 also allow the transfer of stored data to a
computer via the HI9200 infrared transmitter connected to the
computer RS232 port.
In addition, the meters allow the user to enter an ID code to uniquely
identify the instruments.

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 the HI 710005 or HI 710006
voltage adapter to the power adapter plug.
To prepare the instrument for use, connect the pH or ORP (HI98240
only) electrode to the connector located on the top of the instrument.
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.
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 (default is 5 minutes). If in logging
mode, after the period of non-use, the meter will continue to monitor
pH or mV (HI98240 only) and temperature periodically at the end of
every logging interval. Only the "LOG" indication will be visible on
LCD. While storing data in memory, during the sleep mode, the
reading will appear briefly on the LCD.
Before proceeding with pH measurements follow the calibration procedure.
Note: When the use of an alternate function (FNC, CFM and CAL) is
requested, press and hold the ALT key first and then the
second listed key.
Note: To prevent damage to the electrode, remove the pH electrode
from the sample before turning the meter off.
If the meter is OFF, detach the electrode from the meter before
immersing the electrode in the storage solution.

SETUP MODESETUP MODE
SETUP MODE
SETUP MODESETUP 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 have access to stored data.
• To enter this mode ensure the meter is
not logging and then press the ALT and
FNC keys.
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.
• 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.
• Enter the first digit of the code of the parameter you want to set
using the Ç or È key and pass to the next digit with Æ. The
second digit will start blinking.
• Enter the second digit using the Ç or
È 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.
• 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.
PARAMETER SETTINGS
• 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.

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
1110
