Peak
The amplitude and the time-of-flight are measured at
the absolutely highest amplitude value within the gate
with maximum resolution of the instrument.
Flank
The amplitude is measured as in the case of Peak , how-
ever, the time-of-flight is measured at the first point of in-
tersection between the echo and the gate with maxi-
mum resolution of the instrument.
J-Flank / First Peak
These are special parameters for the Japanese market.
Both use the displayed A-scan for evaluation.
The time-of-flight is measured as in the case of Flank ,
the amplitude measurement before the 1st change of di-
rection downwards if the gate threshold is afterwards
not reached yet another time.
When changing the Display Range (see page 125), the
evaluation may vary if several echoes are combined into
one or if one echo is divided among several.
Zero Before
The sound path is measured at the zero crossing of the
rising edge.
Zero After
The sound path is measured at the zero crossing of the
falling edge.
