NOTE: Ports which are not being used should be covered with a blind stop
to exclude temperature and relative humidity infl uences from outside the
chamber.
NOTE: If a door without ports (A000268) is used, the probes to be tested
must be placed inside the measurement chamber. To ensure good air fl ow do
not overfi ll the chamber with probes.
The port adapters can be changed using a port adapter removal tool (A000265) available
from Michell Instruments.
