Function
Zeros your gauge in much the same way that a mechanical
micrometer is zeroed. If your gauge is not zeroed correctly,
all of the measurements made may be in error by some
fixed value.
Use this function to select the type of transducer being
used from a chart of transducer types. This provides
increased linearity between transducers.
Activates the flaw detection mode and view. This feature is
for use with single element angle beam transducers and
used as a general prove-up flaw inspection mode.
Your gauge has adjustable pulse width for both high
penetration and resolution applications. The pulse width
refers to the duration of time the pulser is on. The options
are SPIKE, THIN, and WIDE.
