The material's measured moisture content is relative to the dry
weight (0% moisture) of the relevant material. The stored material
characteristic curves were determined using the Darr (wet and dry
weighing) method. The specified measuring ranges are derived
from this.
Conversion to percent by weight
Percent by weight = (wet weight-dry weight) * 100 / dry weight
Example
Wet weight: 180 g
Dry weight: 150 g
Percent by weight: (180 - 150) * 100 / 150 = 20%
Conversion to water content
Water content % = (wet weight - dry weight) * 100 / wet weight
Example
Wet weight: 180 g
Dry weight: 150 g
Water content %: (180 - 150) * 100 / 180 = 16.6%
Possible causes/solutions
· Readings outside the measuring range (too high, too ·
low): Readings outside the measuring range (too
high, too low): for materials that have not been
specially dried or moistened, the measurement
results should always be within the measuring range.
Residual capacity <10 min: Change batteries.
· Clean sensing electrodes and contacts on the top
of the protection cap.
· If the error message appears again, send the
instrument to Testo Customer Service.
