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
and the time-of-flight is measured at the first point of
intersection between the echo and the gate with max-
imum resolution of the instrument.
●
J-FLANK
The time-of-flight is measured as in the case of
FLANK
, the amplitude measurement from the 1st
change of direction downwards if the gate threshold
is afterwards not reached yet another time.
●
FIRST PEAK
The measurement is made as in the case of
J-
FLANK
, however, with screen resolution.
ATTENTION
The highest echo in the gate does not have
to be identical with the echo for which the
sound path is measured. This can lead to
evaluation errors!
Two measurement arrows are used in order to clearly
identify readings and to avoid any misinterpretations.
The display shows
●
the position at which the sound path (distance) is
measured: arrowhead downwards, and
●
where the amplitude is measured: arrowhead up-
wards.
In addition to the measurement reading, the TOF mode
measuring point (peak or flank) is displayed with a sym-
bol in the measurement line in sound path measure-
ments:
^ = measuring point Peak
/ = measuring point Flank
Examples:
SA^
= sound path within gate A, measuring point Peak
SA/
= sound path within gate A, measuring point Flank
