- Page 2 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.
- Page 3 All cleaning and cover-removing works should be finished at least 48 hours before taking the measurement. VI-D4 meter should not be used to measure concrete on which there is water in a liquid state. Measurements should be avoided in areas exposed to direct sunlight or other sources of heat.
- Page 4 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.
- Page 5 6. Power suppl VI-D4 meter is battery powered. It uses 2 AA type batteries. Both, rechargeable and standard batteries may be used. Battery status shows the remaining capacity of the batteries. If the currently used batteries are almost out of charge, the battery icon will show empty.
