Scitsu tachos are
supplied with a variable resistor in the pickup lead which will need to be
"tuned in" so that the correct pulse strength is received.
This is because magnetos vary quite considerably in their output voltage and
the Scitsu relies on a set voltage band width.
Once tuned in it will remain stable and accurate.
