The metal detector is intended for search in the low-
conductive and non-conductive environments of metal
objectsfromtheferrousandnon-ferrousmetalshidden

Vortex-S instrument represents the portable metal
detector with the eddy current probe (ECP) which is built
in the housing from shock-resistant plastic in which also
electronic elements of the scheme and the power
supply are placed. The principle of operation of the
instrument is based on eddy current method of detection
ofthe hidden metal objects. The built-in voltage stabilizer
provides operability of the instrument at change of
voltage of the battery from 9 to 7 V. In case of discharge
of the battery or rechargeable battery lower than 7.5 V.
the light alarm system «Battery discharge indicator»
works.
1. Lower than 7.5 V. the indicator blinks; 2. Lower than 7
V. the indicator lights and the sound alarm system turns
on; 3. Lower than 6.7 V the instrument is automatically
switched off; 4.
If
in the vibro-mode voltage on a source
decreases lower than 7 V., the instrument automatically

To bring the instrument to controlled object and slow
scanning in close to its surface to run for search.
Scanning speed shall not exceed 0.5 m/s, otherwise
range and probability of detection of the hidden metal
subjects, especially small-sized, decreases a little.
Turning on of a sound and light signaling specifies
existenceofthehiddenmetalsubjects.Theinstrument
possesses enough high resolution capability and
provides when scanning (<0.5 m/s) a separate
signaling about existence of two small-sized metal
subjects located at distance at least 8 cm. from each
other. When pushing the «Sensitivity control» button
(Sens.) the LED lights up "/2" and sensitivity of the
instrument to large metal subjects (a knife, the gun,
etc.) decreases (twice), and small-sized metal objects
(small-sized coins, fasteners, lightnings, etc.) don't
cause actuating of a signaling.Thus, there is an
opportunity to define value of the metal object found in
case of primary scanning by clicking of the button and
repeated scanning of a suspicious section of the
inspectedobject(clothesoftheperson,baggage,etc.).
