Where the scales differ in procedures, keystrokes, etc., the
information for each scale will be separately identified.
If the information is identical for both scales, it will only be stated
one time.

World Scale
WP30 Portion Control Scale
The WP30 Portion Control Scale is a free-standing scale for
general weighing applications, such as portion control.
WC30 Price Computing Scale
The WC30 Price Computing Scale is a free-standing scale for
price totaling of weighed and non-weighed products, from candies
to premium delicatessen products.

World Scale
FCC Note
Verify Correctness of Weight & Price
Legal for Trade Notice
This equipment has been tested and found to comply with the limits
for a Class A digital device, pursuant to Part 15 of the FCC rules.
These limits are designed to provide reasonable protection against
harmful interference when the equipment is operated in a
commercial environment. This equipment generates, uses and can
radiate radio frequency energy and, if not installed and used in
accordance with the instruction manual, may cause harmful
interference to radio communications. Operation of this equipment
in a residential area is likely to cause harmful interference; in which
case, the user will be required to correct the interference at his own
expense.
Check the multiplication of price-per-pound times weight, and
check the displayed weight. Weigh the same package several times
to verify consistency. Keep in mind that some packages which
weigh near the middle of the 0.01-lb increment will normally vary
up or down by 0.01-lb. Greater variation than 0.01-lb indicates a
need for adjustment of the system. In such cases, or whenever
necessary, contact your authorized Hobart Service Representative.
The WP30 and WC30 have been tested by the National Conference
of Weights and Measures (NCWM) National Type Evaluation
Program (NTEP) and found to comply with the applicable
requirements as published in National Institute of Standards and
Technology (NIST) Handbook 44. NTEP certificate 02-071 details
the evaluation. In addition, each scale used for commercial
weighing may require local certification, licensing or approval.
Please contact your local Weights and Measures authority to
determine if your new scale requires additional certification or
licensing. For more information, contact the NCWM at
www.ncwm.net or the NIST Office of Weights and Measures at
301-975-4004.

How to Use This Manual
Online Viewing
World Scale
Hobart uses specific formats to make it easier for you to identify
key selections throughout the manuals. These formats are
described in the following topics:
♦ Online Viewing
♦ Keystrokes and Data Entry Procedures
♦ Quick Steps
♦ World Scale Manual Overview
♦ Special Instructions
If you are viewing this manual online, you have the advantage of
using the cross-referencing feature that has been built into the
document. All Table of Contents page numbers and certain
italicized text have been made into cross-references.
For example, the text may say:
Refer to the topic, Online Viewing for further information.
If you move your mouse directly over the page number or text and
your mouse cursor changes to a pointing hand, then this is a crossreference. If you click on this text, you will be taken to that point
in the document.
You can then use the back arrow on the top of your screen to take
you back to your starting point.
Keystrokes and Data Entry
This manual will use the following methods to explain keystrokes
and data entry procedures:
Procedures
♦ The word PRESS means to press a key on the Control Panel.
1-5 Introduction
• A Short PRESS means to press a key and release quickly.
You will hear one beep.
• A Long PRESS means to press a key and hold it long
enough to hear a second beep.
♦ The word TYPE means to Short PRESS one or more keys on
the Control Panel (WC30 only).
♦ Words in uppercase enclosed in brackets (for example
[SAVE]) represent specific keys.

The World Scale is a durable, compact weighing device. Two
digital displays show the Weight, Unit Price and Total Price to the
Operator and Customer at the same time. The scale can calculate
the value of either By Weight or By Count items and can
accumulate the Total Price for multiple items.
The following features are explained below:
♦ Power Source
♦ PLU Options
♦ Capacity
Powered by six D-cell batteries, the World Scale gives you the
power to use your scale in most trading situations.
The World Scale (WC30 only) offers 30 PLUs as standard –
including seven SpeedKeys which may be used with a “quick-set”
feature for top-selling items. These seven Speedkeys may be userdefined. All 30 PLUs may be password-protected if set up in
Supervisor mode.
The World Scale comes configured from the factory as a
30-lb x 0.005 resolution scale. For other capacities and resolutions
that can be configured, contact your local Hobart Representative.

♦ Leveling the Scale
Remember these for your World Scale.
Do Don’t
DO make sure that the work surface is firm and steady. DON’T lift the scale by the weighing platter
DO avoid direct sunlight. DON’T jar the weighing platter or drop objects on it.
DO avoid locations with vibration.
DO avoid drafty locations.

Leveling the Scale
QUICK STEPS -
Leveling the Scale
1. Locate Level Indicator
2. Adjust Scale Feet till bubble
is centered
Electrical Connections
On the left side of the Console is a Level Indicator. When the
bubble inside is directly in the center of the circle, the scale is level.
There are four Scale Feet located underneath the scale system. You
may need to adjust these feet slightly in the event the scale is not
sitting properly. Proper adjustment of these feet helps you maintain
the scale’s balance and is required when using the scale as Legal for
Trade.
To level the scale:
1. Locate the Level Indicator on the left side of the
Console.
2. Adjust the Scale Feet by turning clockwise or
counterclockwise as necessary until the bubble is
in the middle of the Level Indicator.
The World Scale comes standard with a Battery Pack, which uses
six D-cell batteries.
Tip
• When the Battery Symbol flashes on the
display, you must replace the batteries.
• When not using the World Scale for a length of
time, it is best to place the World Scale in Sleep
mode to extend the life of the batteries. See
Sleep/Wake Modes in this chapter.
