Testing
Once installed, you should test with a weigh scale indicator.
1.
Connect the load bar cables to a Tru-Test indicator.
2.
Turn on and zero the indicator.
3.
Put a test weight (which may be yourself or another person) at one end of the platform/crate and note the stable
reading on the indicator.
4.
Put the test weight at the other end of the platform/crate and note the stable reading on the indicator.
5.
Remove the test weight and note whether the reading returns to zero.
6.
If the two readings differ by more than 1 kg OR the reading does not return to zero, see the
Troubleshooting
section.
Periodically repeat the above tests during use and also before first use if the equipment has not been used for some time.

Troubleshooting
Fault
Remedy
Reading does not return to
zero between animals
OR
Difference in readings at each
end of the platform
OR
Under reading (readings
lighter than expected).
•
Ensure that the platform/crate is not touching objects that may alter the weights.
Typical causes are binding against fixed metalwork or build up of dirt.
•
Check that the load bar feet are sitting evenly on the ground.
•
Check that bolt holes are not misaligned, as this may put a residual load on the load
bars.
Reading is unstable.
•
Moisture in the load bar connectors. Remove moisture from the plugs and caps using
methylated spirits, ethyl alcohol, or a suitable electrical contact cleaner. Do not use
stronger spirits, as they may react with the plastic.
•
Damaged cable. Return the load cell for servicing.
•
Moisture in load cells. Return the load cell for servicing.
Reading moves, display shows
under load or overload.
Damaged cable. Return for service.

Caring for the load bars
•
Ensure that the underside of the platform or crate and gap between the load bar housing and foot is kept free of dirt
and stones.
•
Do not leave the indicator, load bars or plugs immersed in water.
•
Cables should be placed so that they will not be damaged. We recommend routing the cables through plastic pipe or
other conduit to help prevent damage.
•
When not in use, always replace the dust caps on the load bar plugs. When the load bars are connected to the
indicator, screw the two dust caps together.
•
Remove dust and moisture from the plugs and caps using methylated spirits, ethyl alcohol, or a suitable electrical
contact cleaner. Stronger spirits must not be used, as they may react with the plastic.
