Page 4: General Description
Exceeding the limits will damage the probe and stylus assembly. The DP-7 is factory tested and adjusted using the stylus components it is shipped with. Specify the required stylus assembly when ordering to minimize the number of adjustments necessary during set up. -
Page 5: Over Travel Limits And Dimensions
The DP-7 works with the Centroid control to minimize pre-travel variation. CNC11 systems are plug-in ready for the DP-7. CNC10 systems require an additional installation kit. See the Centroid appendix for CNC10 installation kit information. DP-7 SPECIFICATIONS: 0.5” ø 1.5”... -

Page 7: Stylus Assembly Installation And Alignment Procedures
STYLUS ASSEMBLY INSTALLATION AND ALIGNMENT PROCEEDURES Important: Read the complete procedure before starting. The DP-7 is factory adjusted for the stylus and stylus extension that are supplied with it. Using other stylus components will probably require some adjustment. When assembling stylus extensions do not twist or apply torque to the carbon fiber or ceramic composite section. -

STEP 3: Thread the stylus assembly into the stylus mount boss on the DP-7. Insert a wrench into the hole located closest to stylus mount boss. Place the 3/16" wrench, on the flats of the stylus mount boss. Refer to the pictures below. - Page 9 Run-out Adjustment set-up and effect of Set Screw Movement STEP 2: Rotate the spindle by hand (without touching the probe) so that the probe spins through a full 360 degrees and watch the dial indicator to locate the high and low run-out rotation positions of the stylus.

Page 10: When To Check Run-Out
Adjust the stylus tip run-out last. WHEN TO CHECK ANGULAR ALIGNMENT: The DP-7 when shipped with a long stylus assembly is aligned for that assembly at the factory. When replacing stylus assemblies with off the shelf parts it is likely adjustment will be needed. -
Page 11: Angular Alignment Adjustment Procedure
The angular alignment procedure has a high degree of difficulty. Read this entire section and be certain adjustment is necessary before attempting it. Consider having Centroid (TM) perform this adjustment, test the probe and install any up-grades that may be applicable to continue reliable performance. -

STEP 2: Plug the retractile cord into the DP-7 probe and into the digitizing port on the control. The cord ends are keyed to prevent incorrect connection. At the probe end line-up the red dot with the red painted slot on the probe connector, push the plug in until it clicks. -
Page 13: Maintenance And Care
Calibration complete. MAINTENANCE AND CARE Do not submerge or expose the DP-7 to liquids. Wipe off any liquids immediately to prevent internal contamination or degradation of the rubber seal and indicator lens. The probe body is stainless steel and should only be wiped clean with compatible cleaners. -
Page 14: Shipping Instructions
SHIPPING INSTURCTIONS If the probe must be shipped it should be removed from the tool holder and the stylus assembly must be removed from the probe. Use the original plastic shipping tube and insert the probe in the tube with the stylus mount boss located inside the foam ring in the tube. The foam should prevent the stylus mount boss from touching the end of the plastic tube if jarred during shipping. -

Page 18: Grid Digitizing Tips
Good repeatability is not a substitute for low PTV. The DP-7 was developed specifically for 3D digitizing accuracy with long stylus assemblies. Determine the acceptable digitizing error for the project, the probe PTV (3D) must be less than the acceptable error. -

The splice connections are not made until all the cables have been routed. The DSP conduit cable must be pulled through the conduit to the console where the CPU10B is located. - Page 21 14 will flash alternately red green then stay red. Also check for a flashing red LED on the CPU10B daughter card. When the DP-7 is first connected it will flash its outputs and LED indicator light as a diagnostic tool. The corresponding inputs on the control should change (flash) as well.
