Troubleshooting Guide
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?
The other load cell
is defective. Check
it's cable for cuts or
flattened areas and
send it back for repair.
The indicator is defective. Verify this
by substituting a good working indicator.
Check the platform for
debris and mud
interference. Check
mounts for binding and
obstructions.
Connect the load cell to the
other connector on the indicator.
Stand on the load cell, Does it
display approximately twice your
weight?
This load cell is defective.
Check it's cable for cuts or
flattened areas or send it
back for repair. Double check
the indicator using a known
good load cell.
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 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?
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?
One of the load cells is bad. A
good load cell will weigh you at
approximately twice your weight with
only one load cell connected.
Do both load cells weigh you
about the same but not within
20% of twice your weight?
Does the indicator turn on?
Does the scale weigh you
close to your weight?
Does the indicator respond when
you step on the scale?
Check for 12VDC at 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.
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 and
flattened areas.
The other load cell is
defective. Check it's cable
for cuts or flattened areas or
send it backl 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.
Disconnect one of the load cells and stand over
the connected load cell. Does the indicator
display a reading about twice your weight?
Perform the paper clip test. Take
two paper clips and carefully insert
one into pin 2 and the other in pin 3
of either load cell connector jack on
the indicaor. 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.
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
working indicator.
The other load cell is defective.
Check it's cable for cuts or flattened
areas and send it back for repair.
