Signal strength is dependant upon the shape and orientation of the object and whether it is of ferrous or
non-ferrous metal.
The most sensitive point of the search head is its centre.
3 TROUBLE SHOOTING
Any fault conditions encountered can usually be cleared by checking:
•
the battery voltage and cell polarity
•
the battery contacts for spring tension and corrosion
•
the search head plug and socket for good electrical and mechanical connection.
4 MAINTENANCE
The Elcometer Protovale 600 Metal Detector is designed to give many years reliable service under normal
operating and storage conditions.
No special maintenance is necessary, though the unit should be wiped clean of dirt and moisture after use.
Two points in particular will ensure long-term trouble free operation:
•
To prevent damage to the search head plug and socket, keep the threads clean and free from mud and
grit.
•
To prevent corrosion damage from leaking batteries: make sure the unit is switched OFF after use; and
remove the batteries if the unit is to be stored unused for any period of time.
