YES
YES
The other load cell is defective. Check
its cable for cuts or flattened areas or
send it back for repair. Check defective
load cell by connecting it to indicator

NO
Check for debris around
and under platform and
load cells. Check load
cell cables for cuts and
flattened areas.
YES NO
Does the scale weigh you
close to your weight?
Disconnect the load cell cable from the
indicator. Press the indicator “TARE”
button. (indicator display should go to zero)
Stand on the load cell. Does it display a
reading about twice your weight?
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?
The other load cell is
defective, check its cables
for cuts or flattened areas
or send it back for repair.
Does indicator respond
when you step on scale?
NO
Disconnect one of the load cells and
stand over the connected load cell.
Does the indicator display a reading
about twice your weight?
Does the indicator come on?
YES
NO YES
NO
YES NO
This load cell is OK.
Disconnect first load cell
and connect other load
cell to same connector.
Now stand over second
load cell. Does it weigh
about twice your weight?
Disconnect first load
cell and connect other
load cell to same
connector. Now stand
over second load cell.
Does it weigh about.
twice your weight?
Perform a paper clip 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 indicator.
Hold one paper clip in each hand (if they
touch it will not damage indicator) Does

the cables for damage and send
both load cells in for repair.
Indicator is defective. Send it in for
repair. Note: Load cells may also be
defective. Check load cells by
attaching to a working indicator
NO

connector on indicator. Stand
on load cell. Does it display
about twice your weight?
Check platform for
debris and mud
interference. Check
mounts for binding
and obstructions.
YES
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
Connect both load cells
(one at a time) to other
connector on indicator. Do
both load cells weigh you
