MAKING THE METER READY FOR USE:
Put the 4 batteries in place with right polarity.
Turn on the meter by pushing the power button.
If zero is shown on the display, the instrument is ready for use.
Connect the meter to the instrument with the flex provided.

MAKING MEASUREMENTS:

Slide the measuring bar upwards to the upper stop until it clicks in
automatically.
Turn on the meter, or if it is already on, push reset to make the display ready.
Put the porosity instrument without its top in an upward position under the sur-
face needed to be measured.
Put the top on the magnetic head through the front edge of the glider so that the
fabric is between the top and the magnetic head.
Push starter to initiate measurement. Make sure that nothing blocks the way of
the measuring bar!
The instrument signals the start of measurement with a sound.
The instrument issues a sound every 5 seconds after measurement has been
finished.
Measurement results can be read in seconds on the display.
Another measurement can only be started after pushing reset.
IMPORTANT:
Make sure that the rubber sheets on the top and on the magnetic head are free
of dust and stains.
Smooth the tested surface on the magnetic head evenly, without creases or
wrinkles.
When putting on the top, try to fit it on the magnetic head as precisely as pos-
sible.
Airflow through a wet and damp canopy may significantly differ from that mea-
sured in dry conditions. (Especially with older gliders.)
Do not draw conlusions from one measurement, make at least 6-8 tests on a
glider.
The 10000th seconds after reaching the instrument will continue the measure-
ment and the second shows the 10000 second flash.
