• Do not mix new and used batteries in the product.
• Do not mix different types or brands of batteries in the product.
• Ensure that all batteries are inserted with the correct polarity in accordance with the instructions in
this manual and indicated on the product.
• Do not store the batteries in direct sunlight.
• Do not expose the batteries to water.
• Do not expose the batteries to heat or dispose of batteries in a fire.
• Avoid forced discharge of the batteries.
• Do not short circuit the batteries.
• Do not disassemble, apply excessive pressure, pierce, deform or subject the batteries to impact
• Do not swallow the batteries.
• Keep the batteries out of the reach of children.
• If the batteries are swollen or damaged do not use them in the product and exercise caution when
handling them.
• Dispose of waste batteries in accordance with your local environmental and safety laws.
Ensure that you comply with international and national battery transport regulations when transporting
batteries or this product with the batteries inserted To reduce the risk of shipment delays, should you
need to return this product to Renishaw for any reason, do not return any batteries.
Information to the machine supplier/ installer
It is the machine supplier's responsibility to ensure that the user is made aware of any hazards
involved in operation, including those mentioned in Renishaw product literature, and to ensure that
adequate guards and safety interlocks are provided.
Under certain circumstances, the probe signal may falsely indicate a probe seated condition. Do not
rely on probe signals to halt the movement of the machine.
Information to the equipment installer
All Renishaw equipment is designed to comply with the relevant EC and FCC regulatory requirements.
It is the responsibility of the equipment installer to ensure that the following guidelines are adhered to,
in order for the product to function in accordance with these regulations:
• any interface MUST be installed in a position away from any potential sources of electrical noise,
i.e. power transformers, servo drives etc;

Before you begin
• all 0V/ground connections should be connected to the machine “star point” (the “star point” is a
single point return for all equipment ground and screen cables).This is very important and failure to
adhere to this can cause a potential difference between grounds;
• all screens must be connected as outlined in the user instructions;
• cables must not be routed alongside high-current sources, i.e. motor power supply cables etc, or be
near high-speed data lines;
• cable lengths should always be kept to a minimum.
Equipment operation
If this equipment is used in a manner not specified by the manufacturer, the protection provided by the
equipment may be impaired.
Optical safety
This product contains LEDs that emit both visible and invisible light.
The OMP600 is ranked Risk Group: Exempt (safe by design).
The product was evaluated and classified using the following standard:
BS EN 62471:2008 The photobiological safety of lamps and lamp systems.
Renishaw recommends that you do not stare at or look directly into any LED device, irrespective of its
risk clarification.

OMP600 basics
Introduction
Welcome to OMP600, Renishaw’s optical probe that offers an unrivalled combination of size, reliability,
robustness and high-accuracy probing on medium and large machining centres.
Successfully combining patented RENGAGE™ strain gauge technology with the optical transmission
system of the OMP60, the OMP600 provides existing probe users with a simple upgrade to solid-state
strain gauge technology and all the associated benefits this brings:
• excellent 3D performance to allow probing of contoured surfaces;
• improved repeatability in all probing directions;
• a low triggering force combined with low pre-travel variation to provide high accuracy, even when
used with long styli;
• the elimination of reseat failures;
• high resistance to machine tool vibration;
• resistance to shock and false triggering through the use of solid-state accelerometers.
In addition to providing high-accuracy measurement on your machine tool, the OMP600 also offers:
• Faster calibration:
On complex 3D parts, it is common to measure in several different directions. Each direction
of a standard mechanical probe must be calibrated, to ensure that the pre-travel variation is
compensated in the measurement. Performing this calibration for every 3D direction can be
time-consuming.
The OMP600 has almost no pre-travel variation, so a single calibration value may be used for any
probing angle in 2D or 3D. This results in a vastly reduced calibration time. An additional benefit is a
corresponding reduction in errors introduced by environmental changes within the machine during
a long calibration cycle.
• The ability to be used in applications where axial and radial reorientations are used, enabled by the
use of solid-state accelerometers.
NOTE: The auto-reset function is required and recommendations should be followed for optimum
metrology performance (see “Auto-reset function” later in this section).

OMP600 installation guide
2.2
OMP600 basics
Getting started
Three multicolour probe LEDs provide a visual indication of the selected probe settings.
For example:
• switch-on and switch-off methods;
• probe status – triggered or seated;
• battery condition.
Batteries are inserted or removed as shown (see “Installing the batteries” in Section 3, “System
installation” for further information).
On insertion of the batteries, the LEDs will begin to flash (see “Reviewing the probe settings” in
Section 4, “Trigger Logic™”).
Modulated vs legacy optical transmission
The OMP600 can be operated in either modulated or legacy mode. Modulated mode has a higher
resistance to light interference. Certain forms of light interference can cause false triggers or mimic
a start signal and falsely activate the probe. These effects are much reduced when modulated
transmission is selected.
Modulated mode
When set to modulated mode, the probe will only function with the OMI-2, OMI-2T, OMI-2H and
OMI-2C interfaces, or with the OSI with OMM-2 interface system.
Legacy mode
When set to legacy mode, the probe will only function with an OMI or OMM with MI 12.
Multiple probe system
To operate a twin OMP600 probe system, one OMP600 probe needs to be set to PROBE 1 start and
the other to PROBE 2 start. In applications where a third OMP600 is to be used, this should be set to
PROBE 3 start. These settings are user configurable.
The Renishaw OMI-2T interface allows twin OMP600 applications. The Renishaw OSI with OMM-2
interface system allows up to three OMP600 probes to be used on the same machine tool.
NOTE: When used in conjunction with an OMI-2T, or with an OSI with OMM-2 interface system, the
OMP600 switch-on method must be set to “optical on” (standard).
Trigger Logic™
Trigger Logic™ (see Section 4, “Trigger Logic™”) is a method that allows the user to view and select
all available mode settings in order to customise a probe to suit a specific application. Trigger Logic is
activated by battery insertion and uses a sequence of stylus deflections (triggering) to systematically
lead the user through the available choices to allow selection of the required mode options.
