Using Headphones - Velleman CS200 Bedienungsanleitung

5. Hold the search coil level to the ground about 1-2 inches above the surface, slowly move the search
coil over the area where you placed the sample, sweeping the search coil in a side-to-side motion.
6. If the detector detects the item, it sounds a tone, and an arrow and the depth appear on the display
below the target icon.
7. If the detector does not detect the item, make sure that the target mode is set correctly for the type
of metal you are searching for. Also make sure that you're moving the search coil correctly.
5.4 Search coil sweeping hints

Never sweep the search coil as if it were a pendulum. Raising the search coil while sweeping or at the
end of a sweep will cause false readings.

Sweep slowly. Hurrying will cause you to miss targets.

It is better you sweep the search coil from side to side in a straight line and keep the search coil
parallel with the ground.

The detector responds with a signal when it detects most valuable metal objects. If a signal does not
repeat after you have swept the search coil over the target a few times, the target is probably junk
metal.

False signals can be caused by trashy ground, electrical interference, or large irregular pieces of junk
metal.

False signals are usually broken or non-repeatable.
5.5 Adjusting sensitivity
After you have become familiar with how your detector works, it is important to fine tune the sensitivity
to get a good result. Press the touch button SENS on the panel. Then press Up or Dn to increase or
decrease the sensitivity. The level on the segment will be displayed form high to low position.
NOTE: in order to detect a target deeply buried, you can adjust the SENS to a high position. But don't set
the SENS lever to MAX, because the detector will receive interference and false signal from broadcast
antennae and other electronic lines. The detector will have unstable arrow and irregular tone indications.
5.6 Pinpointing a target
Accurately pinpointing a target makes digging it up easier, but it takes practice. We suggest you practise
finding sample on your own property before you start searching other locations.
Follow these steps to pinpoint a target:
1. When the detector detects a buried target, continue sweeping the search coil over the target in a
narrowing side-to-side motion.
2. Make a visual note of the exact spot on the ground where the detector beeps.
3. Stop the search coil directly over this point on the ground. Then move the search coil straight
forward away from you and straight back towards you a couple of times and make another visual
note.
4. Repeat steps 1-3 at a right angle to the previous search line. Make an "X" mark on the ground. The
target will be directly below the "X" at the point of the beep response.
5.7 Factors that affect the detecting
It is difficult to have an accurate detecting result. Sometimes the detecting may be restricted by some
factors:

the angle of the object buried in the soil

the depth of the target

the level of oxidization of the target

the size of the target

electro-magnetic and electrical interference surrounding the object.
If you detect patiently and correctly and practise several times, you will get satisfactory results.

Using headphones

1. Make sure your headphones have a 3.5mm plug.
2. Set the VOLUME knob to zero.
3. Insert the headphones' plug into the PHONE jack. The internal speaker will automatically disconnect.
4. Set the VOLUME knob to the desired setting. Do not listen at extremely high volume levels, as it
may lead to partial or permanent hearing loss.
