Gate A TOF Mode
This function can also be set for gate B, C and IF.
The sound path measurement by means of the echo
evaluation depends on the choice of the measuring
point.
ATTENTION
In any case, the setting of the measuring
point for the calibration and for the subse-
quent test use must always be identical. Oth-
erwise, measuring errors may occur.
Note
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
