Self tests
There are several built-in self tests in the
AA-2000 ZOOM analyzer, which can be
run by the user to make sure the analyzer
is working properly. Press
to start
the test and then follow instructions
given on the display.
LC Meter
Use
to choose one of six modes
(Inductance L, Q, tan
δ
and Capacitance
C, Q, tan
δ
), press
to start measure,
evaluate result, tune range to most
reliable values and restart measure, if
required.
Avoid pick values at series and parallel
resonances (reactance change sign) and
adjacent areas, avoid fast changing
slopes. Pick values from more stable,
persistent areas of chart. In most cases
measures at lower frequncies are more
reliable.
Be aware of many factors that will impact result of measure -stray capacitance and
inductance, nonuniformities of element connection, more complex behaviour of
component at higher frequency.
