METER READING
IMPORTANT: Abnormally high readings may be caused by
the surface salts on newly plastered walls or by contact with
metal or steel reinforcing bars, etcbehind a particular surface.
Readings on concrete should be interpreted with caution
and should be assessed in conjunction with a physical
investigation. The test meter may indicate damp conditions
at very low levels of moisture.
