Over Capacity Limits
Scale Leveling
Die cast aluminum base with an ABS plastic
weight platter. Built-in overload protection.
Adjustable center stop, fixed corner stops.
1/2” high, six-digit LCD
Key panel with ZERO and TEST keys.
Optional remote display with 7 ft. cable.
A level bubble is mounted on the load bridge.
Leveling is accomplished by adjusting the four
feet on the bottom of the scale.
Initial automatic zero setting is ±10% of maxi-
mum capacity—active at power on. Manual zero
setting range is ±2% of maximum capacity—
active using the ZERO key.
Under capacity indication will be given with
dashes appearing on the bottom line of the
display whenever the display is below zero.
Over capacity indication will be given with dashes
appearing on the top line of the display whenever
the weighed item exceeds 9 divisions over the
rated capacity of the unit. The scale will use the
initial zero value for reference for over capacity
determination.
Access to the calibration switch can be secured
with a lead-wire or pressure sensitive security
seal. The remote and primary indicators have no
metrological features that require the use of a
security seal.
The scale has 65,000 internal counts.

Check container for any obvious evidence of
damage. Inspect the unit for shipping damage.
Immediately report any damage to the shipper.
1. Mount the unit on a stable, level surface that
is free from air currents and vibration. Be
sure the weigh platter does not touch any
adjacent surfaces.
2. To install the weigh platter flush with a
countertop, use the dimensions below to
guide your construction.

3. Loosen the collars on the leveling feet. Level
the unit by using the level bubble under the
platter as a guide. Be sure all four feet are in
firm contact with the counter, then tighten all
collars.
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

After the NCI Model 7815 is properly installed
and power is applied, the display will perform a
countdown test to insure all display segments are
functional.
After this test is completed, the display should
show zero (0.0).
If the display indicates a slightly “off” zero condi-
tion (either a number in the display or dashes at
the bottom of the display), press the ZERO key.
When the display shows 0.0, it is ready to weigh.
Place item or parcel on the weigh platter and the
weight will be displayed. This information can be
transmitted when requested by the computer.
Model 7815 scales can have an optional remote
display (shown above). The remote display has a
keyboard and can be used in place of the resi-
dent display. To activate the remote display,
power down the scale, plug the remote display
cable end into the marked socket on the back of
the unit. Reapply power and weight data will
appear on both the resident and remote displays.
The control keys (i.e., ZERO and TEST) are
active on both displays in the Model 7815.
