4. Available scales
Concrete 0-6% H2O
Concrete scale may be used only for concrete surfaces. It shows the relation between weight of
pure water contained in the tested material with its dry weight. The scale range varies between 0
and 6% as 6% is about maximal physically possible content of water in the concrete. The obtained
results should not be confused with moisture emission or any other humiditymeasurement
methods.
Cement Screed (0-6%H2O)
This scale is used to measure the moisture content of cement screed. The content of water is
expressed as a percentage of weight.
Cement Screed (0-4% CM)
This scale is used to measure the moisture content of cement screed. The displayed value is an
approximate value that can be also determined using the Carbide Method (CM).
Anhydrite Screed (0-3.5% H2O)
This scale is meant for moisture measurements in anhydrite floors. The displayed value is an
approximation of a value that normally would be indicated using a CM-measurement device.
Anhydrite Screed (0-1.9% CM)
This scale is used to measure the moisture content of Ascreed. The displayed value is an
approximate value that can be also determined using the Carbide Method (CM).
Caisson 0.3-15.3 Scale (0.3-15.3m)
Scale works in a similar way as the Relative with a range from 0.3 til 15.3m.
Relative Scale 0-100%
Relative scale may be used in humidity level comparison of various materials. Obtained results
should not be interpreted as percentage content of water in tested surfaces. There is no linear
correlation between the outcomes and relative humidity. The scale should be used only as
comparison technique. Scale may be used on the surfaces where direct contact with pure concrete
is impossible because of some layer/covering.
5. Modes & Functions
Normal Mode
The main measuring method of VI-D4 meter is
Normal
mode. In this setting the measured
value is refreshed continuously.
Max. Hold mode
If the measured area is not easily reachable and it is impossible to read the value while
measuring, the Max. Hold mode may be used. After choosing that mode the measured value
is not refreshed continuously. The meter will show only the highest value gained from numerous
measurements.
