Description Of Device; General Function - WOLFF VI-D4 Bedienungsanleitung

1. Description of device:

VI-D4 meter was designed in order to measure concrete humidity. Its unquestionable advantage is
nondestructive method of measurement with simultaneous high accuracy and easiness of use.

4) Anhydrite Screed (0-3.5% H
5) Anhydrite Screed (0-1.9% CM)
6) 15.3 Scale (0.3-15.3m)
7) Relative Scale (0-100%)

1.2. 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.
