Introducing the
ElectriCalc®Pro
Now NEC
®
-Updateable!
The ElectriCalc
®
Pro is an invaluable
calculator for today’s busy electrical
professional. Unlike a regular calcula-
tor, it has intuitively labeled “electrical
keys” and conforms to the 2002 and
future National Electrical Codes , allow-
ing you to solve Code-related problems
quickly and accurately. The most com-
mon NEC tables are now at your finger-
tips!
An important new feature of the Elec-
triCalc Pro is that it is now programmed
to accept future NEC changes, allowing
you to conveniently install future Code
editions in a few simple steps.

Installing NEC Updates
Your ElectriCalc Pro is now updateable
for future National Electrical Code®
editions that are updated every three
(3) years (next Code update is 2005).
To upgrade your unit, follow the instruc-
tions below:
1) Purchase the NEC Update from CI
(see pricing & details from CI’s Web
site: www.calculated.com or call 1-
800-854-8075). This Update is in the
form of a chip that contains the new
Code.
2) Once you receive the NEC Update
chip, you need to install it in your
ElectriCalc Pro:
a)Turn calculator off.
b)As a precaution, remove the bat-
tery (located back of calculator, top
of unit) by sliding battery door out
with your thumbnail. Set aside.
c)Using a screwdriver, pop out the
square tab located in the middle
section on the back of your calcu-
lator.
d)Replace it with the new Update tab
by inserting it into the slot.
e)Replace the battery door.
f) Turn calculator on. Your calculator
is now updated and ready to use.

Key Definitions
Standard Calculator Functions
[On/C] — On/Clear
Turns on power. Pressing once clears
the last entry and the display. Pressing
twice clears all non-permanent values.
[Off] — Off
Turns all power off. Clears the memory
and most internal registers.
[+] [–] [x] [÷] [=]
Arithmetic operation keys.
[0] – [9] & [•]
Used for keying in numbers.
[%] — Percent
Four function percent key.
[ ] Back Space Function
Used to delete entries one keystroke at
a time (unlike the On/C function, which
deletes the entire entry).

6 — ElectriCalc Pro
[Set] — Second Function
Accesses the secondary functions
shown above the keys when pressed
prior to selection.
[Stor] — Store
Used to store values when pressed just
before a storage register (i.e., M+,
AMPS, VOLTAGE, etc.).
Displays: STOR.
[Rcl] — Recall
Recalls a value stored in a register
(e.g., to recall voltage drop % press
[Rcl] [VD%]). Displays: RCL.
[Set] [ + ] — Pi (π)
Constant = 3.141593
[Set] [–] — Change Sign (+/–)
Toggles the sign of the displayed value
(from positive to negative or from nega-
tive to positive).
[Set] [%] — x2
Squares the displayed value.
[Set] [ ] — Square Root ( x )
Square root function.

[Stor] [0] — Cumulative Memory
Adds displayed value to Memory (e.g.,
10 [M+], 20 [M+], [Rcl] [M+] = 30).
Clears when the calculator is shut off.
[Rcl] [0] — Memory Recall
Displays the value saved in (M+).
[Rcl] [Rcl] — Display/Clear Memory
Displays and clears the value saved in
(M+).
[Set] [Rcl] — Clear Memory
Clears the value saved in (M+) without
changing displayed value.
Mode Set-up Functions
[Set] [x] — All-Clear (AC)
Resets all settings and values to their
default settings.

8 — ElectriCalc Pro
[Set] [3] — Three-Phase (3Ø)
Sets calculator to three-phase mode.
Displays: 3Ø.
[Set] [2]
— Ambient Temperature (Amb°)
Permanently enters ambient tempera-
ture for determining ampacity derived
wire sizes. Ambient temperature will
only change when entering a new value
or by resetting the calculator ([Set] [x]).
Defaults to 30°C (86°F). Amb° will
display when the ambient temperature
is other than 30°C (86°F). Displays:
Amb°.
NOTE: The temperature units can be
displayed in Celsius (°C) or Fahrenheit
(°F) by using the preference function
([Set][÷]).
[Set] [4] — Copper/Aluminum
Used to toggle between copper (de-
fault) and aluminum wire types. When
the wire type is revised, any calculated
wire size will be re-calculated automati-
cally. If a wire size is entered with the
wrong wire type, pressing [Set] [4] will
change the material type without
changing the size.
Displays: Al or Cu.
