SKIPPER 5 MOISTURE METER USER GUIDE
WORKING WITH YOUR SKIPPER 5
SCALE 1 - HARDWOOD
a. When testing Wood, select Scale 1 and lightly
press the rubber electrodes directly to the surface.
Read the moisture % from the top line of the
analog dial where calibration is marked from 5% to
30%. If readings are in the high range (red) and if
the audio is turned on, it will sound when readings
go above 18%.
b. If switched on, the audio signal will sound when
readings are above mid-scale.
c. For better accuracy, always take readings with the
length of the instrument parallel to the direction of
the wood grain.
d. Acceptable levels of moisture content depend on
climatic conditions and we advise you to check the
levels acceptable in your area. The table on page
21 shows the approximate relationship between
the ambient relative humidity and equilibrium
moisture content in woods.
e. As a rule of thumb and depending on climatic con-
ditions, exterior wood is generally considered safe
for painting when the moisture content is 14% or
below. Wood below 10% is generally considered
suitable for interior painting. (Always check coat-
ing manufacturers recommendations).
