With the Multi-meter running, fit the calibrator in place and switch it on. Wait some
second for the measurement to stabilize. Then press the button. You will receive the
prompt in Fig.8.8.

Be advised that, answering yes, you will affect all pressure measurements executed
with input channel A. You can inspect the newly acquired sensitivity entering the
microphone sensitivity dialog (see 5.4.4).
8.5 THE LCR METER
This is a particular operating mode of the Multi-meter that gives you the possibility of
measure inductors, capacitors and resistors. This measurement is an impedance
measurement and is carried out in the Internal Mode; please have Chapter 13 as
a reference for what concerns impedance, related connections and operations.
In this mode the Multi-meter takes control of the generator and, when the measurement
is started, outputs a series of sinusoids of variable frequency in order to find the best
one to carry out the measurement. The output frequency can be displayed (with the
magnifier button) together with the measured parameter.
8.5.1 MEASURING AN INDUCTOR
Measuring an inductor is as easy as connecting it as in Fig.8.9, slecting the In-Out Loop
with and press Go. The most critical factor influencing this test are connections; as
with all impedance measurements, if you use pin-to-alligators cables put a great care
in avoiding false contacts which may arise if terminals are oxidized or alligators loose
their bite.
