Probe functions

Probe reset


hcu1_reset_key
NOTE: The probe reset function is only available if it has been integrated by your CMM supplier.
Some Renishaw probe interfaces have a probe reset button mounted on the front panel. The function of this button is to reset the probe sensor to a seated condition, for instance following a manual stylus change. This button has been reproduced on the HCU2 for ease of access. Probe reset is only available from the HCU2 if the motorised probe head is in manual mode.

Please refer to your probing system user's guide or to your CMM supplier for details of the use of this feature.

CAUTION: This button should only be pressed when the probe is physically seated and clear of the workpiece.

Probe DAMPing

hcu1_damp_key Probe DAMPing is a feature of your Renishaw probe interface which reduces the sensitivity of the probing system and helps to reduce unwanted triggering caused by CMM acceleration or vibration during position moves.

It is normally used by the CMM computer to filter unwanted triggers during automatic position moves.

The HCU2 enables probe DAMPing to be set manually to eliminate unwanted triggers during manual position moves. Probe DAMPing is only available from the HCU2 if the motorised head system is in manual mode. In automatic mode probe DAMPing is controlled from the CMM aplication software and motorised head controller and this key has no effect.

The DAMP key toggles between probe DAMPing ON and OFF.

CAUTION: Probe DAMPing must be switched off when measurement points are being taken. Use of probe DAMPing during measurement will significantly affect measurement accuracy.

Audible key press confirmation

hcu1_mute_buttonIt is possible to switch on an audible indicator which emits a tone when any key is pressed. The Audible key toggles between audible tone ON and OFF.

The HCU2 powers up with the audible indicator OFF.

Effect of PICS STOP

If a PICS STOP signal is sent to the motorised head system by the CMM controller while it is in manual mode, the motorised head will react as follows:
