Id Metal Discrimination - KTS-Electronic PULSE AR III User Manual

3. Initially please set the frequency to the lowest level (turn the Freq.-modulator
counterclockwise). By means of Audio control the volume should be set
audibly. To become acquainted with the handling of the device we generally
recommend to start with the lowest frequency adjustment. With advancing
experience it is expedient, to increase the frequency gradually what will have a
positive effect on the search performance.
Since the function of the Reset-button is decisive, the key should be pressed after
each modification:
1. After every activation of the metal detector.
2. After each change of searchcoils.
3. During the search, if sound becomes instable due to bad ground conditions or
geomagnetism.
The change of sound is the first sign for the detection of a metal object. Before
excavation, however, further details should be taken into account and your own
search experience should be used for help.
The more intense the sound, the larger the object and the nearer its position to the
surface. While a high search tone is audible, the searchcoil should be moved in the
close surrounding to determine the shape of the metal object.
Note: Please be certain, that there are no metal objects in the close proximity to the metal
detector during zero balance. This can produce a false calibration and unwanted indication
effects.

Examples for divergent conductivity values:
 light metals (e.g. aluminum)
 copper
 gold and precious metal
Please bear in mind that – depending on soil conditions and size and shape of the
located objects – the measured values can diversify. The indicated values are guide
values, which can be complemented with your own search routine.
Please take not of explanations to error signals on page 12.
