Welcome
to
the
HP-32S
Your HP-32S reflects the superior quality and attention to detail in
engineering and manufacturing that have distinguished Hewlett-
Packard
products for more than 40
years.
Hewlett-Packard stands
behind
this
calculator:
we
offer
accessories,
worldwide
service,
and
expertise to support its use (see inside the back cover).
Hewlett-Packard
Quality
Our calculators are
made
to excel, to last, and to be easy to use.
• This calculator is designed to withstand the usual drops, vibrations,
pollutants
(smog,
ozone),temperature extremes, and humidity vari
ations that it may encounter in normal, everyday worklife.
• The calculator and its manual have been designed and tested for
ease
of
use. We selected spiral binding to let the manual stay open
to any page, and we added many examples to highlight the varied
uses
of
this
calculator.
•Advanced materials and permanent, molded-in key lettering pro
vide a long keyboard life and a positive feel to the keyboard.
• CMOS (low-power) electronics and the liquid-crystal display allow
data
to
be
retained
even
when
the
calculator
is
off,
and
let
the
bat
teries last a long time.
• The microprocessor has been optimized for fast and reliable com
putations using 15 digits internally for precise results.
• Extensive research has createda design that has minimized the ad
verse effects of static electricity(a potential cause of malfunctions
and
data loss
in
calculators).
Welcome
to
the
HP-32S
Features
The
feature
set
of this calculator reflects
needs
and
wishes we solic
ited
from
customers.
The
HP-32S
features:
•
All
functions
available
either
on the
keyboard
orin
menus:
you
do
not have to type their names in.
• Messages and program lines in English, such as DIVIDE
BY
8 in
stead of
ERR
21. Data storage in variables Athrough Z.
• Our traditional RPN
logic,
which saves keystrokes.
• 390 bytes of memory to store data and programs.
•
Advanced
functionality for statistics, base
conversions,
complex-
number arithmetic, integration, and solving for the unknown
variable of an equation.
• ExtensiveHP programming capability, including editing, labeled in
put and output,subroutines,
looping,
conditional instructions,
flags,
and indirect addressing.

Preliminaries
Turning
the
Calculator
On
and
Off
To
turn the
calculator
on,
press
[c].
Note
ON
printed
below
the
key.
To
turn the calculator off, press(ICoffI. That is, press and releasethe
shift key flf)), then press[c] (which has
OFF
printed above it). Since
the calculator has
Continuous
Memory,
turning it off does not affect
any information you've stored.
Toconserve energy, the calculator turns itself off after about 10 min
utes
of
no
use.
Undermost conditions, the calculator's batterieslast wellover a
year.
If yousee the low-power indicator
(C3)
in the
display,
replace
the
batteries as soon as possible. See appendix A for details and
instructions.
Adjusting
the
Display's
Contrast
Thedisplay'sbrightness depends on lighting, your
viewing
angle,
and
the contrastsetting.
To
darken or lighten the
display,
hold down the
fcl key and press
|T|
or |"-l.

The
Letter
Keys
Mostof the keys have a letter written next to them, as shown
above.
Whenever
you need to type in a letter—which is used to identify a
variableor a label—the A..Z annunciator appears in the display, indi
cating that the letter keys are
'active*.
(Variables
are
covered
in
chapter 3.)
Backspacing
and
Clearing
One of the first things you need to know is how to
clear:
how to
correct numbers, clear the display, and, in general, start over.

Description
Backspace.
Erases the last character
before
the cursor(_) or
backs out of the
current
menu.
Fora
completed
number
(no
cursor),
(T| clears the entire
number.
Also
clears error
messages.
During
program entry: deletes the program
line.
Clear
or
Cancel.
Clears
the displayed number to zero or can
cels the current situation (such as a
menu,
a message, a
prompt for input, a catalog, or program entry).
The
CLEAR
menu.
Gives
you options for
clearing
data:
{x},
{VRRS},
{ALL},
and
{2}.
These clear: the current num
ber
(called
"x"),
allvariables, allof
memory,
and statistical data.
During
program entry, the menu includes {PGM},
which
erases
all of program memory.
Using
Menus
There
is a lot
more
power
to the
HP-32S
than what yousee printed
on the
keyboard.
This
is
because
almost
half of the shifted keys are
menu
keys,
which, when pressed, offer you several more functions—
or more options for more functions. This extra power is easier to find
than if each function had its own
key.
