Operation:
•
Switch MODE to VLF to check the state of the batteries in both compartments B1 and B2. If everything
is ok which means the needle is in the green area (BATT) the device can get used. If not do exchange
the batteries.
•
Before any measurement must be a tuning of the transmitting and the receiving coil. To perform the
tuning set MODE to VLF and the rotary knobs GROUND, DISCRIMINATION and SENSITIVITY to their
centre positions. Hold the detection coil 30 cm above the ground and press PUSH. Hold the PUSH-button
and adjust the display needle to 0 by using TUNE.
•
Set MODE to TR1 and press PUSH. At TR1 the device differentiates between base and precious metals.
•
Move the detection coil slowly bidirectional and parallel to the ground in a height of 1 – 5 cm.
•
If the device detects something it will be shown by the LEDs, by the needle of the display and an
indication sound. The reaction of the device depends on the following conditions: a) the material the
found object is made of, b) the size of the found object, c) the deep in which the found object lies and
d) in which angle of the found object is to the detection coil.
•
If the position of the object is located and the class of metal is determined set MODE to TR2 and press
PUSH. At TR2 the device differentiates between different metals of the same class. For the fine tuning of
the measurement turn DISCRIMINATION into the direction of MAX. This will blank out the effect of
other metal items close by. With some practice so it is possible to tell something about the size of the
found object.
•
To detect objects in different levels under the surface turn SENSITIVITY into the direction of MAX. When
an acoustic signal occurs turn the rotary knob back as far as the signal will scrape through. Then the
device measures objects which are situated in this level.
•
To eliminate possible distortion in mineral-rich grounds it is recommended to tune the device with
GROUND. Set MODE to VLF and hold the detecting coil above the ground in 1 – 5 cm height. If the
needle deflects adjust it to 0 with GROUND. If the needle remains on 0 even if you lift and abate the coil
then it is accommodated to the soil conditions. This adjustment can be cancelled by pressing PUSH.
