2 GETTING STARTED 2.1 CHARGING BATTERIES The Elcometer Protovale 610 Timber Metal Detector is powered by internal rechargeable batteries. A fully charged unit will give 9 or 10 hours of operation. 1. Make sure the instrument is switched to the OFF/CHG position.

2.2 CONNECTING THE SEARCH HEAD Screw the TNC plug of the search head into the MUTE socket marked ‘coil’ on the front panel of the control COIL unit, taking care not to cross the threads. SPEAKER GAIN BATT 2.3 SWITCHING ON TEST Switch the machine on by turning the control marked ‘GAIN’...
The most efficient way to establish quickly the presence of metal is to operate the Elcometer P610 at maximum sensitivity (GAIN control rotated fully clockwise); however having established the presence of metal, the sensitivity can be progressively reduced by turning the GAIN control anticlockwise to enable accurate pin-pointing of the metal object to within 5 cm to 8 cm.
4 STRONG SIGNALS AND TARGET PINPOINTING Whereas the signal from an object at its maximum detection distance is weak, the signal from the same object very close to the coil is between one hundred and one thousand times stronger and will cause the circuits to overload.
6 DETECTOR RESPONSE TO DISCRETE OBJECTS 6.1 OBJECT ORIENTATION Non-magnetic (non-ferrous) objects give the greatest signal when they present the largest area; thus a sheet of metal gives the greatest signal when ‘face-on’, and the least when ‘edge- on’. For magnetic (ferrous) objects (e.g. iron or steel) the signal is ‘magnified’...

6.2 EDGE EFFECTS In some cases, an object with a poor response under the centre Non-ferrous of the coil due to its unfavourable orientation will give a stronger signal when under the edge of the coil. In some cases therefore, a ‘difficult’ object will appear as two sharp responses exactly one coil diameter apart, with the true position halfway in between;...

6.3 WIDTH OF RESPONSE Mentally plotting the strength of response against position as the object is scanned across can give yet more information about the object: movement A close object gives sharp responses as it crosses the edges of the coils Distant objects give a more gradual decrease off-centre Extended objects have a sharp response at their edges, and a ‘flatter’...
