PIN-FREE MOISTURE METERS
MANUAL MC-160SA
Explanation to measuring functions:
Without hold function:
When the spring electrodes are moved over a surface, the MC-160SA
continuously takes a new measurement. This function is used for fast
scanning of an area.
With hold function:
The MC-160SA only takes one measurement when the spring
electrodes touch a surface. The value is kept on the display after the
MC-160SA being removed from a surface. This is used for viewing the
result where it is difficult to see the display during operation. A new
reading is taken when the unit is placed on a surface again.
Relative humidity:
For building materials (not wood), the MC-160SA automatically
calculates the Moisture content value (% H2O) into Relative Humidity (%
RH). This function is used when relative humidity is more appropriate
term.
Memory/Average:
Up to 2 measurements can be stored in the memory. The MC-160SA
then calculates the average of values stored in the memory.
THIN MATERIALS
For single materials, thinner than 10 mm, the sensitivity of the meter is
normally not enough. However, comparing measurements to determine
wet spots in the material can still be performed.
To obtain a more accurate measuring result we recommend
measurements in a pile without air spaces between the single parts and
with a minimum thickness of 20 mm for the pile.
BASE
With material thickness < 50 mm the base material is very important.
Avoid a metal base. The best results are achieved if the material to
be measured is hold into the air. Polystyrene material with a minimum
thickness of 20 mm can also be used.
WET SURFACES
In case of material with wet surface a PVC-foil can be used between the
material and measuring springs electrodes.
