MH20i operation

NOTE:  Ensure locking lever is in fully locked position before taking gauging points.

To change the orientation of the probe:

  • Unlock the head by turning the lock lever to the fully anti-clockwise position
  • Grip the body of the probe (avoid touching the stylus or stylus module) and rotate the B-axis until the desired angle indication on the scale is adjacent to the B-axis reference mark, increments are in 15°
  • Rotate the A-axis until the desired angle indication on the scale is at the A-axis reference position, increments are in 15°
  • Lock the head by turning the lock lever to the fully clockwise position
  • Qualify the stylus tip(s) according to the CMM supplier's instructions
  • Change the orientation of the probe to the next desired position and qualify the stylus tip(s)
  • Repeat the qualification process for all desired orientations and stylus tips
  • Commence gauging, ensuring that the correct qualification data is recalled for each head position
  • Periodic re-qualification should be performed according to the following considerations:

CMM supplier's recommendations, particularly in respect of temperature changes.

  • At the start of the working day or shift
  • After an accidental collision
  • After changing any measuring system component (except a pre-qualified TP20 module)
  • If the initial state is unknown or uncertain
