Common reasons for incorrect measurements
•
Don´t position the instrument at a wall that was treated with
mould remover recently
•
Sunlight or other sources of heat or cold that doesn´t correspond
to the surrounding temperature
•
Dripping or sprayed water
•
Danger of condensation because of changing temperature
•
Polluted moisture sensor
•
Foreign objects on the sensor
•
Measuring errors due to too short conditioning time
To demonstrate the importance of temperature adjustment, the table below
shows measuring errors due to a temperature difference of only 1°C / 1.8°F
between the measuring instrument and the substance to be measured at
different ambient temperatures.
10°C (50°F) 20°C (68°F) 30°C (86°F)
10%r.F.
±0.7%
±0.6%
±0.6%
50%r.F.
±3.5%
±3.2%
±3.0%
90%r.F.
±6.3%
±5.7%
±5.4%
At room temperature (20°C/68°F) and an assumed moisture value of 50%r.h.
a deviation of 1°C / 1.8°F between the measuring sensor and the substance
to be measured results in a measuring error of 3.2%r.h. A deviation of 3°C /
5.4°F would result in a measuring error of over 10%.
