4.4 Probing procedure at the contact point
In order to ensure the reliability of the measured values, the following condition must be fulfilled:
the probe 5 should be firmly attached to the probe fixing arm 4 which in turn is fixed to the
mounting pin 3. Make sure that both knurled screws on the fixing arm are tightened.

Probe contact procedure for the reading the measured values
• Use the handwheel 8 (Fig. 1) to rapidly move the measuring head.
• Use the knurled ring to bring the probe into contact with the measuring point on the work piece,
but not right up to the switch point.
• Pause for a second or so.
• Approach the measuring head by continuing to turn the knurled ring slowly until an acoustic signal
confirms the taking of the reading.
• Withdraw the probe from the surface of the work piece.
For optimum results when taking the readings, the measuring point should always be probed with the
same careful regular movement. When the speed with which the measuring head approaches the
work piece is reduced to an absolute minimum at the end of its travel, the probe will make precise and
bounce-free contact. The readings thus obtained will be reliable and highly repeatable.
