Calibration
Your
Capella
was dispatched from the factory in Denmark together
with a Test Report (Calibration Certificate). The Test Report specifies
which transducers have been calibrated (i.e. those which have been
supplied together with the instrument), according to which stand-
ards, and what equipment was used for calibration. Results are list-
ed for each transducer at all standard frequencies.
For DPOAE,
Capella
is calibrated in dB SPL (1 dB SPL = 20
µ
PA); for
TEOAE,
Capella
is calibrated in dB peak.
Calibration has been performed on the supplied probe. If you wish
to use any other probe for testing with
Capella
, please contact your
local supplier first.
Calibration should be performed annually by suitably qualified per-
sonnel, using the appropriate equipment.
