2.2.3 Testing the DC112d/DC112
We recommend that you test the DC112d/DC112 before beginning a measurement,
adjust the sensitivity (if necessary), and test it again after the measurement has
finished.
To test the DC112d/DC112 use the
CB004 or CB006 sound calibrator and
proceed as follows:
1) Insert the microphone of the DC112d/DC112 in the cavity of the calibrator. Make sure
it has been fully inserted, and is parallel to the axis of the calibrator (see figure). This
may require a little force, as the microphone must fit into the calibrator perfectly. Do
not insert the DC112d/DC112 microphone roughly, as it may be damaged.
