3.2 Detection

Envelope

The MET 30+ detector software creates a detection envelope after an automatic
setup is performed, it uses this envelope as a means of detecting metallic
contaminants. For a signal from a metallic contaminant to operate the detection relay
it must produce a vector signal large enough to pass through the periphery of the
detection envelope. (See fig 1a and 1b).

You can alter the sensitivity of the detector by increasing or decreasing the
dimensions of the envelope, known as the width and height. Increasing the envelope
size decreases the sensitivity and decreasing the envelope size increases the
sensitivity. It is found that in the majority of cases altering the width of the envelope
is all that is required to increase or decrease the sensitivity.

breaking out of the detection envelope.
