General Function - WOLFF VI-D4 Professional Handbuch

1. General function

VI-D4 meter calculates humidity of analyzed material by measuring its electrical impedance. The
relation between humidity of certain material and its impedance is directly proportional. Impedance
is measured through generating low frequency electric field between electrodes.
The meter measures low intensity alternating current flowing through electric field and on that basis
calculates moisture of tested material.
2. Constraints
Concrete Moisture Meter VI-D4 does not detect concrete humidity through electricity conducting
materials like metal coverings/ linings, PE-rubber or any wet surfaces. Moisture Meter VI-D4
should not be used to measure concrete humidity on surfaces which are topped with a thick layer of
floor covering material like wood. Meter measurement outcomes show the actual humidity at a time
of measurement.
To turn on the meter press ON/HOLD button.
