The measurement screen is the main screen of the 45MG software. From anywhere in
the 45MG software, simply press [MEAS] to return to the measurement screen. The
power indicator is always present on the left side of the 45MG screen (see "Power
Indicator" on page 27 for details).
The optional waveform trace, called the A-scan, allows a skilled operator to verify that
the signal used to make a thickness measurement is the correct back-wall echo, and
not noise, material anomaly, or the second multiple echo. The A-scan also enables you
to observe indications that may be too small to be measured by the instrument.
The ID bar (available with the Datalogger option), located at the top of the
measurement screen, contains the ID for the actual thickness-measurement location
and the previously stored value (see Figure 3-3 on page 34). The download indicator
( ) appears when the previously stored thickness measurement comes from a file
rather than a newly acquired value.
