has been ventilated. The latest TEWL reading and the message VENTILATE with a
progressing bar alternates on the display until ventilation is finished. A new
measurement can be performed when the message PRESS TO MEASURE is displayed.
The operation can be interrupted after the measurement sequence has started. Press the
operating button once during the countdown or after the long tone. If the measurement
has been aborted, wait until PRESS TO MEASURE appears again after the ventilation.
Ventilation of the measurement chamber
The relative humidity in the measurement chamber has to decrease to the level of the
ambient RH% between measurements. This is automatically controlled. The
ventilating time increases with increasing evaporation readings. The VapoMeter may
be carefully waved to accelerate the moisture evaporation from the chamber,
particularly after high values.
Make sure, that the opening of the measurement chamber is not close to the skin or
other sources of humidity during the ventilation. If the relative humidity inside the
chamber increases during the ventilation, the blue progress bar turns red and
progressing stops. Wave the VapoMeter carefully to speed-up ventilation, if
necessary.
