Troubleshooting

If you experience problems which you are unable to identify or solve satisfactorily, please contact your Renishaw representative for further advice or contact the Technical Support Department at any Renishaw office for free assistance by telephone (see address list on rear cover).

Poor measurement performance:

Possible cause

Solution

Probe or probe extension bar not installed correctly.

Remove probe and / or probe extension bar and re-fit using the S1 spanner.

Stylus configuration too long or not rigid.

Use shorter / stiffer stylus configuration.

Poor stylus assembly.

Ensure that the number of stylus joints is kept to a minimum and all joints are clean and secure.

Contaminated / damaged stylus ball.

Inspect for damage, clean thoroughly with solvent.

Trigger force too high.

Decrease trigger force to the minimum necessary to ensure reliable triggering.

Too few points taken for probe qualification / measurement.

Take a larger number of points on the qualification / feature measurement.

Unwanted triggers during CMM movement:

Possible cause

Solution

Trigger force set too low.

Increase trigger force to the minimum necessary to ensure reliable triggering.

Stylus configuration too heavy.

Reduce mass of stylus configuration.

Reduce stylus length to minimum possible.

Use a lightweight material for stylus configuration (GF or ceramic).

No probe signal:

Possible cause

Solution

Probe not installed correctly.

Remove probe and re-fit using the S1 spanner.

Probe extension bar failure.

Check connections and integrity of probe extension bar.

Contact your CMM supplier or Renishaw representative for further assistance.

Probe failure.

Contact your CMM supplier or Renishaw representative for further assistance.

Probe fails to re-arm after trigger:

Possible cause

Solution

Trigger force set too low.

Increase trigger force to the minimum necessary to ensure reliable triggering.

Stylus configuration too heavy.

Reduce mass of stylus configuration.

Reduce stylus length to minimum possible.

Use a lightweight material for stylus configuration (GF or ceramic).

Probe reseat failure.

Retrigger probe. Many DCC CMMs will attempt to do this automatically (refer to your CMM supplier for details).

If this problem persists, please return the probe to your Renishaw representative for service.
