5.17 Calibration
Probe delay and velocity
Before working with the USM 100, it must be calibrated.
You have to adjust the material velocity and the display
range, as well as allow for the probe delay, depending
on the material and the dimensions of the test object.
To ensure a safe and proper operation of the instru-
ment, it is necessary that the operator be adequately
trained in the field of ultrasonic testing technology.
The USM 100 provides two calibration modes:
● Multi BW (see page 166)
● Multi Step (see page 167)
Note
The angle calculation of angle probes is de-
scribed from page 169.
Choice of the measuring point
The sound path measurement by means of the echo
evaluation depends on the choice of measuring point
(see
Gate A TOF Mode , page 147).
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
For calibration you can use the envelope
curve instead of the A-scan (see
2-Point Cal
Source , page 155).
