3.4 Note about humidity measure
The instrument humidity sensor reacts
rapidly to changes in the amount of water
vapour in the air. However, the probe
temperature changes more slowly. To
avoid errors caused by temperature
differences the probe must always be left
to stabilize to ambient temperature before
starting measurements: the bigger the
temperature difference, the longer the
stabilization time.
Indoors relative humidity should be
measured in a place where the
temperature is as close to the average
temperature of the room as possible.
Measurements made close to heat
sources, such as light bulbs or radiators,
will not give a true picture of the relative
humidity in the whole room.
Do not keep the probe in your pocket. Your
body temperature warms up the probe; if
its temperature is not left to stabilize to
ambient temperature, its relative humidity
reading will not be stable.
