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.

The

ElectriCalc Pro

instantly solves for

the following:

♦Volts, Amps, Volt-Amps, Watts,

kVA, kW, PF%, EFF%, and DC

Resistance

♦Copper or Aluminum Wire Sizes

♦Parallel & Derated Wire Sizes

♦Voltage Drop Wire Sizes, % and

Actual Voltage Drops, Voltage

Drop Distances and Wire Resis-

tances

♦Grounding Conductors Sizes

♦Motor Full-Load Amps

♦Overload Protection Sizes

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.

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).

[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 )

[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

changing displayed value.

Mode Set-up Functions

[Set] [x] — All-Clear (AC)

Resets all settings and values to their

default settings.

[Set] [÷] — Preferences

Use to set default settings or modes

(see “Preference Settings” page 26)

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.
