THE FRONT PANEL
1. Large display for Conductivity, Fertil-
izer, NaCl and TDS
This large LCD displays the conductivity,
fertilizer, NaCl and TDS reading.  The
corresponding symbol will be displayed
along with the measured value.
A "----" signal will ap-
pear on this display
to indicate an out of
range condition.
2. Temperature display
This LCD displays the temperature mea-
sured by the HI7669/2W probe or the
value that was manually set through the
keyboard.  Temperature can be selected
between the Celsius and the Fahrenheit
scale by pressing the °C or the °F key
respectively.
If the probe is not connected when the meter
is turned on, the "25°C" (or "77°F") symbol
with a blinking decimal point will default.

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 mea-
surements.
Temperature compensation can be either au-
tomatic or manual. It can be selected through
the key ATC MTC respectively.
A temperature coefficient factor (for conduc-
tivity 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 co-
efficient %;
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.
