PRELIMINARY EXAMINATION
Remove the instrument from the packing material and examine it
carefully to make sure that no damage has occurred during shipping.
If there is any damage, notify your Dealer.
Each meter is supplied complete with:
• Amplified pH electrode with built-in temperature sensor and
EEPROM and DIN connector
• HI70004 pH 4.01 sachet (1 pc)
• HI70007 pH 7.01 sachet (1 pc)
• Instruction Manual
• AA size Alkaline Batteries (4 pcs)
• Rugged Carrying Case.
Note: Save all packing material until you are sure that the
instrument functions correctly. All defective items must be
returned in their original packaging together with the supplied accessories.
GENERAL DESCRIPTION
HI98140 is a portable logging microprocessor-based pH/temperature
meter, while HI98150 is a portable logging microprocessor-based pH/
ORP/temperature meters.
Both instruments 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 can be performed.
The meters are also equipped with a stability indicator and backlight
feature for comfortable reading even in excessively dark environments.
An 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
3
well as in the laboratory.
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 meter provides 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 weak.
To prolong battery life, the backlight feature is automatically disabled
when the batteries are getting low; a clear 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.
For long term field and lab applications, these meters can be connected
to a 12VDC adapter.
The meters can store measurements in memory at the request of the
user for retrieval at a later time.
HI98140 and HI98150 also allow transfer of data to computer
through the RS232 port.
In addition, the meters allow the user to enter an ID code to uniquely
identify the instruments.
Made of tough, lightweight ABS material, the water-resistant rugged
casing is built to last.
The meters are in compliance with IP67 standards: dust-tight,
protected against the effects of temporary immersion in water and
designed to provide laboratory results and accuracy under harsh
industrial conditions.

INITIAL PREPARATION
ON/OFF
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 (HI98150
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 5
minutes of non-use (this feature is enabled by default and can be
disabled through setup code 20). To reactivate the instrument press
the ON/OFF key.
Before proceeding with pH measurements follow the calibration procedure.
Note: When the use of an alternate function (DEL, FNC, CFM, GLP,
RCL and CALT) is requested, press and hold the ALT key first
and then the second listed key.
Note: to prevent damage to the electrode, remove it from the sample
before turning the meter off.
If the meter is OFF, detach the electrode from the meter before
immersing it in the storage solution.

SETUP MODE
Setup can be used to view data regarding instrument status (e.g.
battery charge) or to change the meter parameters (e.g. time).
• To enter this mode press the ALT and
FNC keys when the meter is in measurement mode.
• The setup code "00" will blink on the
lower LCD and "Set" will be displayed on
the upper one.
• Select the code of the desired
parameter using the or
key.
• Press ALT and CFM to confirm the
code.
Note: If ALT and FNC are pressed before code confirmation, the meter
will default to measurement mode.
• If the selected parameter is password protected, the lower LCD will
display "PAS" and the password must be entered to proceed.
Otherwise, the current parameter value will be displayed.
PASSWORD PROTECTION
Setting of time, date and calibration alarm time-out are password
protected and the user will be asked to enter the password to change
these parameters. After code confirmation the upper LCD will display
"0000".
• If password is set to 0000 (factory setting), just press ALT and
CFM to confirm.
• If password is set to a value different from 0000, enter the
password with the up and down arrow keys and then press ALT
and CFM to confirm.
• If password is incorrect the meter displays the "WRONG" indication
and asks for the password again.
• If password is correct, the meter provides access to the parameter.
8
PARAMETER SETTINGS
• Once the parameter code (and password
if needed) has been entered, the current
value of the selected parameter on the
upper LCD and the parameter code on
the lower LCD will be displayed. The parameter or a part of it will
blink (e.g. only the hour blinks if time has been selected).
• Enter the new value using the arrow keys.
• If there is another part of the parameter to be set (e.g. minutes
for the time), press RANGE to gain access and then enter the new
value using the arrow keys.
• Press ALT and CFM to confirm the value.
• If the entered value is not acceptable, the "WRONG" indication
will be displayed for a few seconds and then the meter will ask for
a correct value.
• If the confirmed value is accepted, the meter will pass to the next
parameter (asking for the password if it is protected).
Note: If ALT and FNC are pressed before parameter value confirma-
tion, the meter will not update the parameter and after
escaping will ask for a new setup code.
The following table lists the setup codes along with the description of
the specific setup items, their valid values and the factory settings
(default):

The meter automatically checks for entered time/date accuracy as follows:
0≤hh≤23; 0≤mm≤59; 01≤dd≤28/29/30/31; 1≤MM≤12; 1998≤YYYY≤2097.

To change the password, the correct code must be entered first. If the password
has been forgotten, the password protected features are no longer accessible;
in this case contact your nearest Hanna Service Center.
Some of the setup parameters are explained below.
Code 00 - Setting the identification (ID) code
When using several identical meters it may be useful to uniquely
identify them by assigning an ID code to each meter.
• Select code 00.
• Enter a 4-digit value using the arrow keys.
• Press ALT and CFM to confirm the value.
Code 20 - Auto-off
The auto-off timeout is fixed at 5 minutes.
• Select code 20 to enable/disable this feature.
Code 22 - Battery level test
• Select code 22.
• If the meter is connected to an external power adapter, the LCD
will display "LINE" otherwise it will display "bAtt" on the upper
display, and the remaining percentage
of battery charge (100% means fully
charged battery and 0% corresponds to
the minimum battery voltage that allows
the meter to operate).
Note: the battery level test is also performed any time the meter is
turned on.
