GENERAL DESCRIPTION
Hanna Instruments HI9032 is a microprocessor-based, bench-top, conductivity meter
designed for the laboratory stringent demands,
with the ability to perform five types of measurements:
•Conductivity (4 different ranges: 0.0 to
399.9 µS/cm, 399 to 3999 µS/cm, 3.99 to
39.99 mS/cm, 39.9 to 99.9 mS/cm)
•Fertilizer Concentration (F1 or F2 in
the range 0.00 to 39.9 g/l)
•NaCl of sea water saturation (range 0.0
to 130.0%)
Commands are easily accessible through the
user-friendly keyboard:
Through the COND key the meter is set in
the conductivity range, TDS key selects Total
Dissolved Solids measurements, NaCl key
sets the range to NaCl measurement, and the
FERT key selects 1st or 2nd fertilizer measurements.
Temperature compensation can be either automatic or manual. It can be selected through
the key ATC / MTC respectively.
A temperature coefficient factor (for conductivity measurements) can be also selected
through the %TC key (from 0.0 to 3.0%).
The TDS factor (for TDS measurements) can
be selected through the FTR key (from 0.01
to 0.99).
The unit includes memory storages for all
calibration data even after the unit is shut off.
HI 9032 is equipped with two liquid crystal
displays:
•A large one in two sections (primary and
secondary LCD) indicates conductivity,
TDS, NaCl, Fertilizer and temperature coefficient %;
•A smaller one indicates temperature.
The meter also incorporates a standard R232C
output to allow serial communication with a
host computer; a series of programs can be
selected for the setting of the R232C baud
rate.

OPERATIONAL GUIDE
Make sure that the instrument has been calibrated before taking measurements (see calibration procedures on page 21 for conductivity, page 31 for NaCl and 35 for fertilizer).
Connect the conductivity probe to the
meter securely by aligning the pins
with the socket on the back of the
meter, pushing the plug in and tightening the threaded ring.
Connect the temperature probe to the
back of the meter for automatic temperature compensation or for temperature measurements.
If possible, to minimize any EMC interferences, use plastic beakers for
the solutions.
•Immerse the conductivity probe into the
solution submerging the
holes of the sleeve in the
sample.
Agitate the probe lightly in
the solution to remove any
air bubbles which may
have been trapped inside

TAKING TEMPERATURE MEASUREMENTS
Taking a temperature measurement is very easy.
Connect the temperature probe
ON
to the instrument and turn the
meter on by pressing the ON key.
Dip the liquid/general purpose
temperature probe HI7669/2W
into the sample and allow the
reading on the TEMP. display
to stabilize (1 or 2 minutes).
Note: If the temperature probe is not con-
nected when the meter is turned on,
the instrument will automatically default a temperature of 25.0°C (or 77.0°F)
on the TEMP.
LCD with a
blinking decimal point.
AFTER MEASUREMENTS
When all measurements are
OFF
completed the meter should be
turned off by pressing the OFF
key and the probe cleaned.
See page 59 for the probe cleaning and maintenance procedure.
Note: The probe body and sleeve are very
susceptible to damage due to temperatures exceeding 50°C (122°F). If the
probe is exposed to high temperature,
the bond between the rings and the
probe body may become impaired and
the probe will not function properly, in
which case it has to be replaced.
CONDUCTIVITY CALIBRATION
INITIAL PREPARATION
There is a choice of 4 memorized buffers.
Choose the solution whose conductivity value
is closer to the value of the sample measured:
•84 µS/cm@ 25°C using HI7033 (or
HI8033) conductivity solution
•1413 µS/cm @25°C using HI7031 (or
HI8031) conductivity solution
•12.88 mS/cm @ 25°C using HI7030 (or
HI8030) conductivity solution
•80 mS/cm @ 25°C using HI7034 (or
HI8034) conductivity solution.
Rinse the probe thoroughly in distilled water
or if possible with a small amount of the
calibration solution. This is to minimize contamination of the calibration solution and secure higher accuracy.
When possible, use plastic beakers to minimize any EMC interferences.

INTERFACE WITH PC
Data transmission from the instrument to
the PC is now much easier with the new
HI 92000 Windows® compatible application
software offered by Hanna Instruments.
User friendly, HI 92000 offers a variety of
features and has an on line help feature to
support you throughout all situations.
To install HI 92000 you need a 3.5" drive
and few minutes to follow the instructions
conveniently printed on the disk's label.
IContact your Hanna Dealer to request a
copy.
To connect your HI 9032 to the PC use
HI 920010, available through your Hanna
Dealer. Make sure that your meter is
switched off and plug the connectors, one
into the meter RS232C connector, the other
into the serial port of your PC.
Note: Cables different from the HI 920010
may use a different configuration. In
such case any communication between the meter and the PC is not
possible.
If you are not using Hanna Instruments
HI 92000 application software, please find
here below some additional information to
help your connection to the PC.
SETTING THE BAUD RATE AND THE COMMAND PREFIX
See program # 1.
CHANGING THE COMMAND PREFIX
Sometimes it is necessary to change the
command prefix. If your computer already
uses the DLE character for control purposes, sending it to the conductivity meter
can be difficult or cause your computer to
behave erratically.
To avoid this problem, you can change the
command prefix to almost every ASCII character (0 - 127 decimal).
To change the command prefix, refer to
PGM 2 operation.
The carriage return is the only character
that cannot be used as a command prefix.
Good choices for command prefix are ESC
(ASCII code 27), SO (ASCII code 15), or
any printing character you will not use for
other purposes; e.g. the C symbol (ASCII
code 64).
SENDING COMMANDS FROM PC
With terminal programs such as, for example, Telix®, Windows Terminal®,
HyperTerminal®, it is possible to remotely
control your HI 9032. Use HI 920010 cable
to connect the meter to the PC, start the
terminal program and set the communication options as follows: 8, N, 1, no flow
control.
Command Types
To send a command to the pH meter the
scheme is: <DLE> <
command>
<CR>
This line makes the computer send a Data
Link Escape character, the command expressed as a number or a 3-character sequence) and a CR character.
Note: Windows Terminal® and all the other
terminal programs that support the
ANSI escape sequence, represent
the DLE character by the string '^P'
and the CR character by the string
'^M'. E.g. the line '^PPHR^M' sets
the range to pH.
