PIN-FREE MOISTURE METERS
MANUAL MC-380XCA
Relative humidity F3:
To be used for building materials only not wood. The MC-380XCA auto-
matically calculates the Moisture content value (% H O) into Relative air

Humidity (% RH). This function is used when relative humidity is a more
appropriate term.
Memory/Average F4:
Up to 16 measurements can be stored in the memory. The MC-380XCA
then calculates the average of values stored in the memory.
THIN MATERIALS
For single materials, thinner than 5 mm, the sensitivity of the meter is
normally not enough even with the bottom sensor. To obtain a more ac-
curate measuring result we recommend measurements in a pile without
air spaces between the single parts and with a minimum thickness of 15
mm for the pile.
BASE
With material thickness < 50 mm the base material is very important To
Avoid a metal base. The best results are achieved if the material to be
measured is held into the air. Polystyrene material with a minimum thick-
ness of 0 (8") cm can also be used when using the Measuring Springs.
It is sufficient with 2.5 cm (1") of polystyrene mateial if the internal (bot-
tom) sensor is used.
WET SURFACES
In case of material with a wet surface a PVC-foil can be used between
the material and measuring springs. For the Internal (bottom sensor) a
PVC foil is not necessary.
