FAQ: MicroVib - Cable Repairs And Pinouts

Warning: Use Caution When Performing Local Repairs On DSS Cables

Double check to insure you are making the correct connections. Several DSS products (such as the Photo-Tach) are not protected against reverse polarity and can easily be damaged by use with a miss-wired cable. Equipment damaged in this way is not covered under warranty.

Important Note: Do not ever attempt to repair high temp cables! Field repairs of high temp cables can greatly affect data accuracy.
