7. Measuring
This chapter describes the steps that are required to perform measurements
with the product.
Particular probes must be plugged in or switched on and registered (radio
probes) according to the variable that is to be measured.
Some probes require a warming-up phase until they are ready to measure.
The heat transfer coefficient (alpha) must be set before the U value can be
calculated.
º See CALCULATION, p. 51.
For calculating U value please refer to the documentation enclosed with the
temperature probe for calculating U value (0614 1635).
For simultaneous measurement of the material moisture via a stray field probe
and a radio humidity probe, the radio probe must first be logged on and the
corresponding material selected. Then the instrument must be switched off, the
stray field probe attached and, after switching on again, the material selected
for the stray field probe.
