1.1 About this manual
This manual is divided into chapters by the chapter number and the large text at the top
of a page. Subsections are labeled as shown by the 1.1 and 1.1.1 headings. The
names of the chapter and the next subsection level appear at the top of alternating
pages of the manual to remind you of where you are in the manual. The manual name
and page numbers appear at the bottom of the pages.
1.1.1 Text conventions
Key names are shown in bold and reflect the case of the key being described. This
applies to hard keys and on-screen or soft keys.
Displayed messages appear in bold italic type and reflect the case of the displayed
message.
1.1.2 Special messages
Examples of special messages you will see in this manual are defined below. The
heading words have specific meanings to alert you to additional information or the
relative level of hazard.
ELECTRICAL WARNING!
THIS IS AN ELECTRICAL WARNING SYMBOL.
ELECTRICAL WARNINGS MEAN THAT FAILURE TO FOLLOW
SPECIFIC PRACTICES OR PROCEDURES MAY RESULT IN
ELECTROCUTION, ARC BURNS, EXPLOSIONS OR OTHER HAZARDS
THAT MAY CAUSE INJURY OR DEATH.
CAUTION!
This is a Caution symbol.

1.2 Installation
1.3 Electrical installation
1.3.1 Pluggable equipment
Pluggable equipment must be installed near an easily accessible socket outlet.
1.3.2 Wet conditions
Under wet conditions, the plug must be connected to the final branch circuit via an
appropriate socket / receptacle designed for washdown use.
Installations within the USA should use a cover that meets NEMA 3R specifications
as required by the National Electrical Code under section 410-57. This allows the unit
to be plugged in with a rain tight cover fitted over the plug.
Installations within Europe must use a socket which provides a minimum of IP56
protection to the plug / cable assembly. Care must be taken to make sure that the
degree of protection provided by the socket is suitable for the environment.
DANGER: RISK OF ELECTRICAL SHOCK. NO USER SERVICEABLE
PARTS. REFER TO QUALIFIED SERVICE PERSONNEL FOR SERVICE.
CAUTION: Installation, configuration, and servicing are only to be done by
qualified service personnel as authorized by Avery Weigh-Tronix.
CAUTION: The power cable must be connected to an earth-grounded electrical
outlet. The electrical supply must have a circuit breaker with an appropriate
rating to protect from over-current conditions.
For your protection, all electrical (110V or 230V) equipment used out of doors or
in wet or damp conditions should be supplied from a correctly fused power
source and protected by an approved ground fault protection device (RCD,
GFCI etc.)
IF IN DOUBT SEEK ADVICE FROM A QUALIFIED ELECTRICIAN.

3 Initial Setup
3.1 Unpacking the Scale
1. Remove contents of the shipping container.
2. Inspect the scale for evidence of shipping damage. Immediately report any
damage to the shipper.
3.2 Installing the Scale
1. Mount the scale on a stable, level surface that is free from air currents and
vibration. Be sure the scale platter does not touch any adjacent surfaces.
2. To install the scale surface flush with a countertop, use the dimensions on the
following page to guide construction.

3. Loosen the collars or jam nuts on the leveling feet. Level the scale by using the
level bubble under the scale platter as a guide. Be sure all four feet are in firm
contact with the counter, then tighten all collars and jam nuts.
4. Make sure all power cords, remote display cables, etc., are not touching the
live weighing surface.
5. Plug the unit into an appropriate voltage outlet that is properly grounded.

4 Operation
4.1 Power Up Test Sequence
When the scale is first powered on, it will perform a test sequence. During this
sequence, the display will show the following:
lThe model number and the software revision level.
lA numeric counting test for all segments of the display. During this test, a
test of Random Access Memory (RAM) and a test of Read Only Memory
(ROM) is performed.
4.2 Performing a Normal Weighment
If everything is OK, the display will show zero weight and the scale is ready for use.
1. With the scale powered on, make sure the scale platter is empty and the display
is at zero. If it is not, press the ZERO key …
0.00 is displayed.
2. Place an item to be weighed on the scale platter …
The scale will display the gross weight.
3. Remove the item from the scale platter.
If RAM or ROM error is reported, you must press the TEST key to acknowledge the
condition. See Error Codes and Troubleshooting on page 35.
When first powered on, if the scale is outside the ± 10% zero window, center dashes
are displayed, - - - -
If necessary, reapply power to reset the initial zero setting. Refer to Error Codes and
Troubleshooting on page 35 if the problem persists.

4.3 Operation Controls
ZERO Key The ZERO key will zero the scale if weight is stable, and acts as the NO or
SCROLL key in the Menu Mode and as the INCREASE key in the Gravity
Mode.
TEST Key The TEST key can be used to perform the initial power-up test sequence,
recall diagnostic routines, or view the configuration information. This key
also functions as YES or ACCEPT in the Menu Mode and as the
DECREASE key in the Gravity Mode.
Figure 4.3 Optional Remote Display
All NCI 7800 bench scales, except the 7885, can have an optional remote display. If a
remote display with keyboard is used, then Switch 3 (shown in Figure 1) determines
which display keyboard is functional.
Switch 3 Settings:
Closed= internal display keys operational
Open= external display keys operational
The remote display must be connected to the RJ45 port (DISPLAY) prior to power up
to operate properly.

ROM (RO) – Performs a checksum of all locations of ROM in the processor. Displays
PASS or FAIL.
INPUT/OUTPUT (I/O) – Data is output by the scale and through the use of a loopback
connector. The data is immediately read back into the receive channel and verified
