MATL 2PT: Performs a two-point calibration. This option allows the user to
automatically calculate the velocity by entering a second known sample thickness.
Refer to page 39 for further info.
VELOCITY: Function to calibrate the DFX-8 by setting the velocity to a known
material velocity. Refer to page 94 for further info.
ZERO: Used to zero the transducer and calibrate the screen. The DFX-8 is zeroed
in much the same way that a mechanical micrometer is zeroed. If the DFX-8 is not
zeroed correctly, all of the measurements made using the DFX-8 may be in error by
some fixed value. Refer to the section on page 39, for further info.
3.4 DISP (display) – Menu
VIEW: Selectable RF, +RECT, -RECT, RECTFW views. Refer to page 27 for further
info.
DELAY: Provides the user the ability to change the start position of the A-SCAN
views. Refer to page 28 for further info.
RANGE: Provides the user the ability to change the overall range/depth of the
viewable measurement area. It functions a lot like a zoom on a camera. Refer to
page 28 for further info.
UNITS: Toggle between English or Metric units. The readout will change from
inches to millimeters.
BRIGHTNESS: TFT high speed color display. An arbitrary scale of 1-20 has been
implemented, with the brightest setting at 20. Refer to page 97 for further info.
COLORS: Provides the user with a variety of different color schemes to select from.
There are two schemes for each main color option. Refer to page 98 for further info.
DIM: Allows the user to conserve battery life by diming the display after idle for a
specific amount of time – OFF, 30, 60, 90, 120 seconds. Once dimmed, a single
press of any key will restore the screen brightness. Refer to page 99 for further info.
RECT WAVE: Provides the user an outlined or filled view option when the display
setting is in RECT (rectified) wave mode only. Refer to page 100 for further info.
DETECT MARK: Selectable graphics option for the point of detection on the
waveform: Line, Box, Dots, None. Offers the user a graphics preference on how
they prefer to view the detection on the waveform.
WAVE AVERAGING: The DFX-8+ is equipped with wave averaging to eliminate
noise for a clear waveform image. Not recommended for high speed scanning.
