potentiometer useless.

Check the metal shaft is coming
right back into the base of the
black tube. Ensure there is no
grass or soil build-up preventing
it from doing so. Also check the
large washer at the bottom of
the shaft is not catching on the
bottom of the plate.
Clean the Platemeter and zero
calibrate if required.
Check the cog is running smoothly
on the shaft. If the counter is
mounted too close to the metal
shaft there will be quite a lot of
friction when taking a reading.
If the counter is mounted too far
away from the metal shaft; the
cog is liable to jump a notch easily
Re-assemble the Platemeter.
