9. Using Advanced Gaging Features
The 45MG has many advanced thickness-measurement features that contribute to
making the gage a more versatile instrument, including gain, extended blank, B-Scan,
and DB Grid.
9.1 Adjusting the Gain with Dual Element Transducers
With D79X series dual element transducers, you can manually adjust the gain by
pressing [GAIN/WAVE ADJ]. The 45MG offers two types of gain adjustments:
• The standard feature allows the user to set the gain to HIGH (+10 dB),
standard (default), and LOW (
−6 dB).
• When the waveform (option) is activated, the user can adjust the gain in 1 dB
increments.
The gain value is expressed in decibels (dB), and appears near the lower-right corner
of the display (see Figure 9-1 on page 150).
