Modes Of Operation

The RWS (Roof and Wall Moisture Scanner) has two

operating modes, each with two ranges of sensitivity.

EIFS Mode (Yellow LED selected on MODE switch.)

is for moisture scanning of exterior insulation and fin-

ish system (EIFS) and similar type of construction

cladding as well as polyurethane and polystyrene foam

insulation and other types of low-density insulation sys-

tems applied to the building envelope.

Roof Mode (Red LED selected on MODE switch) is for

moisture scanning and leak tracing of built-up and sin-

gle ply roofing systems.

Each of these measurement modes incorporates two

sensitivities, which are activated by pressing the

RANGE switch:

Yellow LED for lower sensitivity and lower penetra-

tion. Red LED for higher sensitivity and deeper pene-

tration.

How It Works

The R.W.S. is an electronic instrument powered by one

9volt PP3 or similar battery. It operates on the princi-

pal of electrical impedance measurement. This means

that a harmless, low frequency, non-destructive signal

is sent from the two rubber coated electrodes at the base

of the instrument through the surface of the material

being tested, deep into this material. See Figure 2.
