12.3 ENABLING FLAW MODE
To use Flaw Mode, an angle beam transducer and dual lemo to single microdot cable are required.
These are available from Elcometer NDT.
1. Attach the dual lemo to microdot cable and angle beam transducer to the gauge.
2. Press MENU, scroll to the PROBE menu and then highlight the FLAW MODE function.
3. Use LEFT and RIGHT to adjust the value of the FLAW MODE function (OFF, ON, PEAK):
•
OFF - Disables FLAW MODE
•
ON - Enables FLAW MODE
•
PEAK - Enables the FLAW MODE and PEAK HOLD options and view. When this option is
enabled, the peak hold symbol is displayed on the right side of the display (to reset to
zero, press CLR).
4. Press MEAS to return to the measurement screen.
Note: When flaw mode is activated, a transducer delay will still be configured from the previously
loaded transducer. This will only affect the position of the starting point from the initial pulse. The
zero delay can be set to zero by loading the default setup located in the setup menu. Alternatively,
you can load a factory flaw mode setup, and begin making any adjustments necessary.
Description
Horizontal gridlines on the display represent
increments of 25% of the full screen height
The thickness reading normally occupying
this space is not relevant to flaw detection. It
is replaced by a dashed line
The peak hold symbol is only visible when
flaw mode is set to peak. Indicates the high-
est amplitude reflection detected during a
scan. Pressing CLR will reset the position of
the peak hold symbol to zero
Vertical gridlines on the labelled with quad-
rant numbers. Unlike thickness mode they do
not correspond to the material thickness
