K7102RS – METAL DETECTOR KIT K7102RS
To come up against an electric cable while drilling a hole in a wall can have catastrophic consequences.
Likewise drilling into gas water or central heating pipes can be
extremely hazardous. With a handy metal detector it can now be
determined beforehand whether there are metal objects to be found in a
wall ceiling or floor.

An LED indicates
if a metal object is in the vicinity. If an audio signal is also
desired space has been provided on the PCB for a buzzer ( type like SV4/12S ) to be connected
(not included).

The PCB has been specially constructed to fit entirely into to the separately available box.
- Metal detecting distance adjustable: up to 8cm (3.15)
- Power supply: 9V battery (not incl.)
- Dimensions: 56 x 64mm (2.2 x 2.5)
Troubleshooting Hint:
If you experience difficulties with the calibration of the unit (I.E. if
the LED doesn’t turn off when there isn’t any metal present ) replace
C1 with a ceramic 1.2nF (122) capacitor. This behaviour is due to a
spread on the component values and differences created when winding the
coils.
