Check for water marks on the indicator board or
load cell connections (potentiometers).
Indicator
Sometimes the indicator shows a weight when the
load cells are disconnected. If you do this and the
indicator becomes more stable, it is most likely
elsewhere in the system.
Check visually for traces of oxidation. If found,
heating the solder contacts can solve the problem.
Cables
Bad connections cause changes when moving the
scale.
Bend and move the cable briskly especially where
the cable is moving continuously when lifting.
While doing so, look at the display to see if it reacts
to the movements.
The
potentiometers
with which we
calibrate the
output of the
load cells are
mechanical parts
and are sensitive
to humidity,
shocks, and
vibration.
Move the board and put pressure with fingers on
the potentiometers while looking at the display to
see if it reacts. Do not touch the contact.
Load cells.
If connected independently to the indicator, it can
be checked which one is unstable and which one is
not.
