Resistive:
If geometrical capacitance, C
0
, is unknown it can be set by the user by entering a permittivity
(dielectric constant), e ', for the material. Entering a permittivity, e ', will let the system calculate
an approximate C
0
making use of the material models available. Yet, one must be aware that
the accuracy of the absolute values are limited by the accuracy of the entered permittivity. If
the geometrical capacitance is unknown and an approximate permittivity is given, the
geometrical capacitance is calculated as follows:
The impedance value, Z, used in the calculation is the first measurement point in the actual
measurement.
1.5 Getting Started with IDAX
This describes how to perform a diagnostic measurement on a specific test specimen. More
details about the software functions can be found in
IDAX System Control and IDAX Results .
It is recommended to start using IDAX by going through the procedure in this section in order
to become familiar with the instrument and the software. This procedure is also a good test to
perform whenever a confirmation of the proper functioning of the instrument is required. This
test is executed using the standard equipment delivered with IDAX.
Before starting to use IDAX certain preparatory procedures must be followed.
