TOF MODE
The sound path measurement by means of the echo
evaluation depends on the choice of measuring point.
The following settings are possible:
●
PEAK
(peak measurement)
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
(flank measurement)
The amplitude is measured as in the case of
PEAK
,
however, the time-of-flight is measured at the first
point of intersection between the echo and the gate
with maximum resolution of the instrument.
●
J-FLANK
The time-of-flight is measured as in the case of
FLANK
, the amplitude measurement before the 1st
change of direction downwards, when the gate
threshold is afterwards yet again not reached, is de-
termined with the maximum resolution of the instru-
ment. In the case of larger values for the function
RANGE
, it may happen that several points are com-
bined into one. In these cases, the evaluation no lon-
ger corresponds to the displayed A-scan.
●
FIRST PEAK
The measurement is made as in the case of
J-
FLANK
, however, with screen resolution. If the eval-
uation using the displayed A-scan is of prime impor-
tance,
FIRST PEAK
should be preferred.
