Problem
VapoMeter fails to start
or complete a
measurement.
VapoMeter fails to
"power-down".
The TEWL readings do
not seem reasonable.
VapoMeter fails to
transfer TEWL readings
to PC
Before requesting repair check the following:
The batteries may be low. Change the batteries.
Remove and replace the batteries to reset the
processor. If necessary, change the batteries.
Check that the temperature and relative humidity
readings are correct. If not, allow time for the
VapoMeter to acclimatize to new ambient conditions
and re-measure.
Check that the measuring chamber is far enough from
sources of evaporation
measurements. The TEWL value may be affected if the
RH% in the chamber differs from the ambient RH%
when starting a measurement.
Ensure that the standard and small adapters are used
with the correct adapter mode. Always use one of the
adapters.
Ensure that the device is placed on the skin at the right
moment (during the long tone on the zero after the 3-2-
1 countdown).
Check that the device is in close contact with the skin.
The TEWL value may be affected if the chamber is not
properly closed by the measured surface (normally
skin) during the measurement.
If the PC connection in the Menu is ON, but the
wireless connection symbol
