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

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.
