Choosing the measurement mode
You have to choose the suitable measurement mode for
the task. By doing so, you define the method for operat
-
ing the instrument or the data used for determining the
measurement result.
You have a choice between the following measurement
modes:
S-IP
The measurement mode S-IP is available for single-el-
ement probes.
The wall thickness is determined on the basis of the ul-
trasonic time of flight from zero up to the last zero cross-
ing before the first flank crossing detected in gate A. The
ultrasonic time of flight is corrected by the probe delay
line which is calculated during the probe zero offset (
see
Section Probe zero offset, page 5-25).
This measurement mode is suitable for non-coated ma-
terials with smooth, parallel surfaces.
S-PEAK
The measurement mode S-PEAK is available for single-
element probes.
The wall thickness is determined on the basis of the ul-
trasonic time of flight from the last zero crossing before
the amplitude peak in gate
A up to the last zero crossing
before the peak echo in gate
B.
This measurement mode is suitable for non-coated ma-
terials with smooth, parallel surfaces.
S-FLANK
The measurement mode S-FLANK is available for sin-
gle-element probes.
The wall thickness is determined on the basis of the ul-
trasonic time of flight from the last zero crossing before
the first flank detected in gate
A up to the last zero
crossing before the first flank crossing detected in
gate
B.
This measurement mode is suitable for coated materials
with smooth, parallel surfaces.
