YELLOW
LED
will light.
3)
Select Range
: press RANGE switch to toggle
from Low Range (Yellow LED) to High Range
(Red LED) or visa versa.
LOWER PENETRATION RANGE
(
Yellow LED inset in range switch will light
) is
suitable for use on systems incorporating up to
1” (25mm) thickness of insulation.
HIGHER PENETRATION RANGE
(
Red LED inset in range switch will light
) is for
use on systems with greater than 1” (25mm)
thickness of insulation.
4)
Hold the
RWS
by the grab handle and place it so
that electrode is in full and firm contact with the
surface over a known dry area. Adjust the sen-
sitivity control knob until the needle is just
above zero on the analog meter.
NOTE:
On a laboratory mock up on an area where plywood
Sheathing substrate was less than 15% moisture con-
tent, zero reading corresponded to a setting of 5 on the
sensitivity knob of R.W.S., This was on a 1” expanded
polystyrene (EPS) insulation plus lamina over plywood.
See Fig 3. overleaf. (This setting may vary, depending
on site conditions, specifications and environmental
conditions).
