When adjusting, identify the screw Step 2 location with the lowest radial displacement and tighten that screw, aiming for the average of the highest and lowest indicator readings. Remove protective film from surface of RESM20. Repeat this process until the DTI readings are within ±5 µm at the screw locations.

TONiC FS quick-start guide This section is a quick-start guide to installing a TONiC FS system. More detailed information on installing the system is contained in the following sections of the installation guide. INSTALLATION Ensure scale, readhead optical window and mounting faces are clean and free from obstructions. Plug the readhead cable into the Ti/DOP interface under the cover plate and reassemble interface. -
Page 15: Cable Connection
Route the cable away from operating environments that will exceed the EMC limits defined in IEC 61800-5-2 Annex E. Use only Renishaw approved cables between the readhead and the interface. The customer is responsible for verifying the product function where the readhead to interface cable has been re-terminated, including the installation of extension cables. -
