    ESD STM 11.11-2001 guidelines. 2. The metal (plated aluminum) surface is used for volume resistance and resistivity measurements made using ESD STM 11.12-2000 guidelines. C. A BNC/Dual Banana Receptacle adapter is provided for use with the PRF-911 Concentric Ring fixture. Cautions & Warnings A.
  • Page 5 To avoid electrical shock, do not touch the fixture, electrodes or test bed when power is being applied. B. The PRF-911 is designed to be used in audit environments at test voltages of 100 volts or less. Exceeding 100 volts greatly enhances the risk of personnel shock hazards, and may damage or change materials being measured.
