Time-of-Flight Mode
The EPOCH 6LT is capable of displaying time-of-flight (TOF) sound path data for a
gated indication. Time-of-flight is the location of the reflector in terms of
microseconds.
The time-of-flight mode does not divide the measurement reading value by two. The
entire time-of-flight through the test piece in both directions is displayed.
When the instrument is set up to display distances in time-of-flight mode, the
Velocity
parameter (in the
UT
dialog box) becomes inactive. This is because time-of-
flight mode does not use the material velocity to calculate sound path measurements.
