Digi-Star Scale - Troubleshooting Guide
Check for 12VDC at the junction between the
AC/DC converter 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 it in for repair.
Does the indicator turn on?
Does the indicator respond
when you step on the scale?
Does the scale weigh you close to
your weight? (Within 20%)
Disconnect one of the load cells and stand over
the connected load cell. Does the indicator
display a reading about twice your weight?
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 verify that it does not weigh.
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 twice your weight.
The other load cell is defective. Check its cable
for cuts or flattened areas or send it back for repair.
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, connect the
other load cell to the indicator (use the
same connector). Stand over this load cell.
Does the indicator display a reading
approximately twice your weight?
This load cell is defective. Check its cable for cuts
or flattened areas or send it back for repair. Double
check indicator using a known good load cell.
Perform the paper clip test. Take two paper clips
and carefully insert one in pin 2 and the other in 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.)
While inserting the paper clips, does the reading on
the indicator jump around and/or settle on the
number “1” on the left side of the display?
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?
Try connecting the load cell to the other connector
on the indicator. Stand on the load cell; Does it
display approximately twice your weight?
The indicator is defective. Verify this by
substituting with a good working indicator.
Do both load cells weigh you the same
but not within 20% of twice your weight?
One of the load cells is bad. A good load
cell will weigh you at approximately twice
your weight with only one cell connected.
Both load cells are defective and the indicator
is probably OK. Check the cables for damage or
send both load cells in for repair.

Check the platform, and load cells for debris
and mud interference. Check mounts for
binding and obstructions.

The scale system is probably
OK. Check for debris around and
under the platform and load
cells. Check for warped or
damaged mounts on platform.
Check for debris under or around the scale
mounts or platform. Check the load cell cables
for cuts or flattened areas.
Disconnect one load cell cable from the indicator.
Press the indicator “TARE” button. (The indicator
display should go to zero.) Stand on the load cell.
Does the indicator display a reading about twice
your weight?
No

The indicator is defective. Send it in for repair.
Note: Load cells may also be defective. Check load
cells by attaching to a good working indicator.
