INTRODUCTION
The MSV100 exploits two electrical phenomena to 1) accurately locate wood
studs and joists and metal behind walls or inside furniture and 2) detect
energized AC outlets and “live” wires carrying AC voltage behind walls or
ceilings.
The first phenomenon—the so-called fringing field effect—refers to the
change in the capacitance of a material produced by its slight spreading of a
local electric field. In the case of the MSV100 (and most pinless moisture
meters), this field is generated by the instrument itself. When you power on the
MSV100 (by pressing the
PUSH
button on its left side), two plates behind its
rear panel are charged with opposite polarity and pulsed at a high frequency.
This causes current to flow, creating a three-dimensional electromagnetic wave
that extends about 2 in. (50mm) perpendicular to the instrument. When the
back of the MSV100 is placed against a wall, ceiling or fabric, the increased
