INTRODUCTION
Congratulations on your purchase of a Digi-Star Stock Weigh
scale system which is the simplest and most reliable animal
weighing system on the market today. Due to the large number of
load cell capacity options, Stock Weigh scale systems can be
customized to fit your animal weighing needs. The indicator Auto-
Lock feature allows scale to weigh active and restless animals
within ±1% of actual weight. This manual will cover load cell and
other hardware options available in Stock Weigh system. The
load cells option available include following: SW3300 (3300 lbs
capacity), SW6600 (6600 lbs Capacity), SW10K (10,000 lbs
capacity), SW14K (14,000 lbs capacity).
PRODUCT CHANGES AND IMPROVEMENTS
We reserve the right to make changes in design, to add
improvements to or otherwise modify our electronic scale
products without incurring an obligation on goods previously
purchased and to discontinue supplying any parts listed when the
demand does not warrant production.

Install all load cells either widthways across the chute or
lengthways parallel to the chute.
Align load cells so centerlines are lined up (or within ½” (12mm)
of each other)
All load cells must be installed in the same direction so that
weight is distributed evenly.
Each corner of the chute must be level for accurate weighing.
This ensures that the load distributed equally.
IMPORTANT: Do Not weld to load cells with load cell cables
connected to the indicator. If you must weld with load cells
connected, locate welder ground so that current will not flow
through the load cell.

Installation & Operation

Assemble load cells to deck as shown on page 25. Make sure
both load cell cables come out the same side as the indicator
support and the cable plate (located under one of the side
channels).
Assemble indicator support, 1” ram mount and handle/wheels
option as shown on page 25. The ram mount should be mounted
on the channel support side which has the cable plate.
Load cell cable routing: Loosen cable retainer plate and push the
plate outward. Begin by taking the two cable load cell connectors
and feed them through the 1.5” diameter hole from the bottom
toward the indicator support, Figure 3. Weave the load cell cable
through the support arm toward the indicator, Figure 4. Attach the
load cell connector to the indicator and pull any excess cable
back down toward the deck.
At each load cell, push the cable through the retaining plate slot,
Figure 1 and Figure 2. All extra cable is tucked inside the deck
channel. When complete, push the cable retaining plate toward
the deck to close off the channel. Tighten the three ¼” bolts to
hold the retaining plate in position.
MAINTENANCE
There are no moving parts and no lubrication required. The only
maintenance required is periodic cleaning of the mounts and the
area below the scale to assure free and unencumbered operation
of the scale. If a pressure washer is being used, do not spray or
direct high pressure stream at the load cells. Load cell damage
may occur.
Stand over each of the 4 corners to troubleshoot for problems.
Corners should weigh the same within ± 1% maximum error.

TROUBLESHOOTING GUIDE
STOCK WEIGH 3300, 6600, 10K, 14K WITHOUT J-BOX
START
YES NO
Does the indicator come on?
The other load cell is defective.
Check its cables for cuts or flattened
areas or send it back for repair.
Does the Indicator respond when you
step on the scale?
YES
Does the scale weigh you
close to your weight?
YES
Check for debris around
and under the platform and
load cells. Check for
warped or damaged
mounts on platform.
Check for debris
around and under the
scale mounts or
platform. Check the
load cell cables for
cuts and flattened
areas.
NO
Disconnect one of the load cells and stand over
the connected load cell. Does the indicator
display a reading about twice your weight?
NO
Check for 12 VCD at the AC/DC convertor power cord. If you
do not have a multimeter, use a car battery to power the
scale. If the Indicator still does not come on, send in for repair.
The other load cell is
defective. Check its cable
for cuts or flattened areas or
send it back for repair.
Check the defective load
cell by connecting it to the
Indicator and verifying that it
does not weigh.
YES
NO
Disconnect the first load cell and
connect the other load cell to the
same connector on the Indicator.
Does the Indicator display a
reading about half your weight?
Disconnect the load cell cable from the
Indicator. Press the Indicator “TARE” key.
(The Indicator display should go to zero).
Stand on the load cell. Does it display a
reading about twice your weight?
NO
This Load Cell is OK.
Disconnect the first load cell
and connect the other load
cell to the same connector.
Now stand over the second
load cell. Does it weigh twice
your weight?
Disconnect the first load cell
and connect the other load cell
to the same connector. Now
stand over the second load cell.
Does it weigh twice your
weight?
YES
NO
One of the Load Cells is Bad. A
good load cell will weigh you at
about twice your weight with only
one load cell connected.
Perform the paper test. Take two paper clips and
carefully insert one into pin 2 and the other into
pin 3 of either load cell connector jack on the
Indicator. Hold one paper clip in each hand (if
they touch it will not damage the Indicator). Does
the reading on the Indicator jump around?
Both load cells are defective.
The Indicator is probably
OK. Check the cables for
damage and send both load
cells in for repair.
NO
YES
The Indicator is defective. Send it in for
repair. Note: Load cells may also be
defective. Check the load cells by
attaching to a good work in Indicator.
YES NO
The load cell is defective.
Check its cables for cuts or
flattened areas or send it back
for repair. Check indicator
using a known good load cell.
Connect the load cell to the
other connector on the
Indicator. Stand on the load
cell. Does it display about twice
your weight?
YES
Check the platform
for debris and mud
interference. Check
mounts for binding
and obstructions.
YES
NO
YES
The other load
cell is defective.
Check its cables
for cuts or
flattened areas
or send it back
for repair.
Connect both load cells (one at a time)
to the other connector on the Indicator.
Do both load cells weigh you about
twice your weight?
NO YES
The Indicator is defective.
Verify this by substituting a
good working Indicator.
Do both load cells weigh you
about the same but not within
20% of twice your weight?
NO
YES
NO
