Page 11 OMP60 basics Getting started Introduction Three multicolour probe LEDs provide visual The OMP60 is an optical machine tool probe, indication of selected probe settings. suitable for use on medium to large machining and mill-turn centres. It is designed to resist For example: optical interference, false triggering and shock.
Page 12 Trigger Logic™ Modes of operation Trigger Logic™ (see Section 4, "Trigger Logic™") The OMP60 probe can be in one of three modes: is a method that allows the user to view and select Standby mode: where the probe is awaiting a all available mode settings in order to customise switch on signal.
Page 13 Shank switch on Shank switch off Approximately 0.5 seconds. NOTES: In optical start, the following total system time applies before OMP60 is ready to start probing: Legacy (start filter off) 0.5 sec Legacy (start filter on) 1.5 sec Modulated 0.5 sec...
Page 14 Probes subjected to particular forms of light interference may accept spurious start signals. The OMP60 can be operated in either ‘Legacy’ or ‘Modulated’ optical transmission modes. Legacy mode A start filter improves the probe’s resistance to these effects.

Page 25 NOTE: Must be used with steel styli. For optimum metrology performance do not use a weak link with ceramic or carbon fibre styli. Fitting stylus with weak link onto OMP60 In the event of excessive stylus overtravel, the weak link is designed to break, thereby protecting the probe from damage.
Page 26 OMP60 installation guide Installing the batteries NOTES: See Section 5, "Maintenance" for a list of suitable battery types. If dead batteries are inadvertently inserted into the probe, the LEDs will remain a constant red. Do not allow coolant or debris to enter the battery compartment.
Page 27 Mounting the probe on a shank (or machine table) NOTE: In instances where the OMP60 is to be used with a shank switch, it will be necessary to remove the plug from the rear of the probe using pliers. This should then be substituted with the bobbin (A-4038-0303).
Page 28 OMP60 installation guide Stylus on-centre adjustment NOTES: During adjustment, care must be taken not to rotate the probe relative to the shank, as damage 3.10 to the bobbin (A-4038-0303) can occur where fitted. (x 4) If a probe and shank assembly is dropped, it must 1 Nm be rechecked for correct on-centre adjustment.
Page 29 Stylus trigger force is set by Renishaw. The 3.11 user should only adjust trigger force in special circumstances e.g. where there is excessive machine vibration or insufficient force to support the stylus weight.

Page 38 OMP60 installation guide Changing the batteries CAUTIONS: Do not leave exhausted batteries in the probe. When changing batteries, do not allow coolant or debris to enter the battery compartment. When changing batteries, check that the battery polarity is correct. Take care to avoid damaging the battery cassette gasket.
Page 39 NOTES: After removing the old batteries, wait more than 5 seconds before inserting the new batteries. Do not mix new and used batteries or battery types, as this will result in reduced life and damage to the batteries. Always ensure that the cassette gasket and mating surfaces are clean and free from dirt before reassembly.
