Test

1. Connect a 9V battery to the battery holder.

2. Go to a place where NO metal object is known to be in the vicinity.

3. Turn preset RV1 fully clockwise.

4. Turn RV2 fully anti-clockwise.

5. Depress the push button and hold it in during the final adjustments.

6. Turn RV1 anti-clockwise until the LED goes out.

 All further remaining adjustments are now concerned with RV2 only.

To set to maximum sensitivity: turn RV2 until the LED is weakly lit. When the detector now comes into the

vicinity of a metal object, the LED will be more brightly lit. This gives an indication of the distance and/or the

size of the metal object.
