Noise suppression
The following measures might become necessary: If the
counter output actuates inductive loads such as relays
and valves, a freewheeling diode for DC current and an
RC element for AC current must be installed. Use
shielded cables for feeders to counting-, zeroing- and
keyboards lock input. The screening should be
connected on one side via a capacitor (e.g. 10 nf) to
protective earth ground.
