BIP Calibration

BIP Calibration

The BIP (beam index point) must be calibrated regularly as it can change due to wedge wear.

  1. With a brand new wedge, the BIP is where it should be
  2. When the wedge start to wear, it is not unusual that it wears more at the front or at the back changing the BIP
  3. To calibrate the BIP, the probe is placed on an IIW block
  4. The signal from one of the radius is peaked (maximized) by moving the probe forth and back
  5. When the signal is peaked, the wedge is marked in line with the center of the radius

Good calibration of the BIP is essential in order to do precise measurements.
