Resolution
The cog has wound off.
Replace - Request a spare cog from
your service agent.
Potentiometer damaged. The
Potentiometer is the shaft part that
drives the cog. NB: Under no
circumstances should you apply CRC
or a light oil to the potentiometer. It is
a dry bearing and any lubricant will
render the potentiometer useless).
Send the plate meter to your service
agent for repair.
Check the metal shaft is coming right
back into the base of the tube. Ensure
that there is no grass or soil build-up
preventing it from doing so. Also
check the washer at the bottom of the
shaft is not catching on the bottom of
the plate.
Clean the plate meter.
This means that the plate meter does not know where the bottom is - therefore
does not record the reading.
