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. Insert the coaxial plug of the charger into the CHARGE socket on bottom panel of instrument, and plug
charger into mains outlet.
2.2 CONNECTING THE SEARCH HEAD
Screw the TNC plug of the search head into the
socket marked ‘coil’ on the front panel of the control
unit, taking care not to cross the threads.
2.3 SWITCHING ON
Switch the machine on by turning the control marked
‘GAIN’ clockwise from the OFF position until it just
clicks on.

3 USING THE INSTRUMENT
1. Holding the search head well away from any metal, rotate the gain control fully clockwise and then
press and release the button marked BATT/ZERO. The instrument is now zeroed and set to maximum
sensitivity.
The unit will produce a faint tick-over sound.
2. Hold the search head above the ground and sweep the instrument back and forth.
When metal is detected, the meter deflects progressively to the right and the audible tone
simultaneously increases its ticking note past a low frequency buzz and progresses through a tone of
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. Whilst no damage is caused, this produces two effects: the unit will tend to give a
saturation signal over a wide area surrounding the object, and even when the coil is moved well away, the
indication will persist for a finite time until the circuits recover from the overload. To minimise this,
progressively turn the GAIN control anticlockwise.
Accurate pin-pointing may also be helped by moving the search coil into the region of strong signal, and
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 ‘edgeon’.
max min
6.2 EDGE EFFECTS
In some cases, an object with a poor response under the centre
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; this is particularly true of small iron
nails.

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:

9 MAINTENANCE
The Elcometer Protovale 610 Timber 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.
To prevent damage to the search head plug and socket, keep the threads dean and free from mud and grit.
The instrument does not contain any user-serviceable components. In the unlikely event of a fault, the
instrument should be returned to your local Elcometer supplier or directly to Elcometer. Contact details can
be found on the outside cover of these instructions, or on the Elcometer website, www.elcometer.com
