Zero Calibration
1. After setting the correct ultrasonic sensor frequency, set the sound
velocity to 5900m/s (see
Adjusting the Sound Velocity
for details).
2. Select the proper receiving gain (see
System Setup
for details).
3. Coat the 4mm calibration test block with coupling gel (R7950) and
place the sensor on the calibration test block while ensuring the
