SCHEMATIC DIAGRAM

OPERATION

Turn the unit on, set to LOW or HIGH mode. Hold
one washer in each hand using your thumb and
index finger.

The speaker sounds as the LED

flashes.

Now squeeze the washers harder, the

frequency should increase.

This simulates your

galvanic skin resistance lowering due to stress. The
kit is ready for use.

Ask the person holding the

washers questions and see if they are telling the
truth.

You can also use the kit as a moisture indicator for
plants. Remove the washers and strip ends of the
two wires 1". Insert the wires into the soil, the more
moisture in the soil the faster the circuit oscillates.
