In a few seconds the measure stabilizes to the final result shown in Fig. 8.10. This was
a 4.8H nominal inductor; the panel shows also the test frequency that, in this case, is
2510Hz. The same procedure should be carried out when measuring resistors or
capacitors.

8.6 INTERACTION BETWEEN THE MULTI-METER AND FFT
The Multi-meter uses the same capture and processing units as the FFT control panel.
To perform a measurement it programs the FFT routines (changing FFT settings to
match its needs) and then effectively starts an FFT measurement in background.
The two panels can be opened and can work together but FFT always acts as master
while Multi-meter as slave. In this situation the Multi-meter window's title is changed
to 'Multi-Meter (FFT slave)' to reflect this new state; the Go and Stop buttons are
disabled as you operate the slave panel from inside FFT, starting and stopping the
reading with the FFT's Go and Stop buttons; the input channel follows the FFT one
while the integration setting become meaningless; this is because the user's has
control over FFT averages which precisely define the measurement integration.
Nevertheless, during slave operation, it is possible to select the displayed parameter
and its unit. It is not possible to select LCR operation as LCR meter uses different
measurement capabilities.
As soon as the FFT control panel is closed it releases Multi-meter from the slave state;
then Multi-meter is ready from stand-alone operation and is fully functional as described
above.
