Safety Before unpacking and installing the RVP system, the user should carefully read the safety instructions below and ensure that they are followed at all times by all operators. The RVP vision probe system should only be used with the REVO-2 head.
The REVO-2 head and probe electronics are powered from the UCC S5. The head motors are powered from the SPA3. The VPCP and VMCP are powered by a separate power supply that is supplied by Renishaw. Any additional backlighting is powered by a separate power supply that is supplied by Renishaw.

The RVP system comprises a probe and a range of modules that are automatically interchangeable with all other probe options available for REVO. This flexibility means that the optimum tool can be selected to inspect a wide range of features, all on one CMM platform.
Design principles of the RVP system The RVP system uses an industry standard CMOS image sensor to capture and then detect the position of features using the contrast between light and dark areas of the image. Data points are projected on to the location where the image contrast changes from light to dark. A detailed calibration model of the lens system transforms the co-ordinates of the projected point on the image to real-world, three dimensional co- ordinates on the part.
RVP probe RVP is the probe component of the system that houses the sensor and digital signal processor. There are currently two vision modules that attach to the probe body that enable the inspection of a range of size and shape features.

RVP is fully automated through MODUS and UCCsuite. VPCP and VMCP change ports There are two new change ports that can be mounted to an MRS rack system to allow the automated changing of all the RVP probe and module components.
* NOTE: T-nuts must be used with the MRS system. However T-nuts and D-nuts are compatible with the MRS2 system. NOTE: Please refer to the REVO-2 change port system spacing guide (Renishaw part number H-1000-5408) for full details of the recommended spacing for positioning all sensors and artefacts on the MRS / MRS2 rail.

Fixing VA11 calibration artefact and VA90 to CMM The VA11 calibration artefact is designed to be fixed securely to the bed of the CMM to allow accurate and repeatable calibration of the RVP system components. The diagrams below show how to fix the VA11 to the bed of the CMM.
The image on the right shows a correctly exposed front lit feature. The front edge of the hole is sharp and there is good contrast between the dark material in the hole and the bright, front lit hole area. When using front lighting, more RVP image settings may need to be adjusted to get the optimum contrast and to reduce unwanted reflections.
A cleaning kit for the precision ball seating and permanent magnet is available from your Renishaw supplier (part number A-1085-0016). It comprises strips of yellow tack material. Use the yellow tack to clean the areas indicated with arrows numbered [1] on the image below.
Optical windows The RVP probe and module optical windows should be cleaned using an optical lens cleaning kit to blow or brush debris away from the window. If debris is still visible, then the optical window should be carefully wiped with a lint free bud and high-purity isopropyl alcohol (IPA).
RVP user's guide www.renishaw.com Technical terminology Stand-off This is the distance between the end of the vision module and the plane at which a feature will be at the sharpest focal distance to provide optimum image capture. Issued 06 2022...
This is the maximum size area that will be projected onto the CMOS sensor when the correct stand-off distance is used. Any feature requiring inspection with RVP must be located within the field of view to allow inspection. Issued 06 2022...
RVP user's guide www.renishaw.com Depth of field The depth of field specifies the range over which a feature can deviate from the nominal stand-off distance and still be measured with acceptable levels of metrology performance. If features are measured outside the recommended depth of field range, metrology performance and accuracy will decrease.
