When using MULTECHO mode, be sure to observe gate b to verify
that the correct backwall multiple has been detected. Purpose
and operation of gate b are described in detail in Sections 13.5
through 13.7.
To assure the best measurement in FLANK TOF mode, ampli-
tude of significant backwall or discontinuity echo signal(s) of the
test object should be approximately the same as the amplitude of
the corresponding echo signal(s) from the test block during cali-
bration. For example, if backwall echo amplitude from the test
block was 100%, then the amplitude of the backwall echo of the
part under test should be adjusted to approximately 100%.
To display measurements in the enlarged display area, press
or
until the S= value is highlighted in the measurement line.
Displayed measurement values may be stored in the on-board
data logger of the USN52 L or transmitted via RS-232C to a printer,
computer, or other RS-232 compatible device.
Proceed to Chapter 15 for instructions on recording measurements
in the on-board data logger.
Proceed to Chapter 16 for instructions on transmitting measure-
ments to an external device via RS-232C.
