Using the Fast mode with the Freeze function may help in
obtaining measurements as quickly as possible.
f.
Note that a corrosion gage is not designed for flaw or crack
detection, and cannot be relied upon to detect material
discontinuities. A proper evaluation of material
discontinuities requires an ultrasonic flaw detector such as
the Panametrics-NDT
TM
Epoch series used by a properly
trained operator. In general, unexplained readings by a
corrosion gage merit further testing with a flaw detector.

For further information on the use of dual element
transducers in corrosion gaging, or for information on any
aspect of ultrasonic testing, contact Panametrics-NDT.
h.
Often, performance on hot, corroded materials will be
considerably improved by the use of the Gain Adjust
procedure or the Material Sensitivity Optimization
procedure. High temperature couplants are generally less
efficient than those used at lower temperatures, so the MG2
will work better when sensitivity is adjusted or optimized to
accommodate high temperature conditions.
