USER GUIDE TB-9084 Concentric Ring Probe Installation, Operation and Maintenance Made in the United Kingdom Resistivity and Resistance Per ANSI/ESD STM11.11 section 12.0 CONVERSION TO RESISTIVITY, When it is appropriate to convert a resistance obtained by this test method to an equivalent resistivity in ohms per square, multiply the resistance measurements obtained by this method by ten. The conversion factor of ten is derived from the geometry of the electrode assembly. NOTE: Conversions to resistivity may not be valid for materials that are laminated, plated or metallized with conductive materials. This fact should be understood when users of this test procedure are required to satisfy specifications given in ohms/square. Repeatability Per ANSI/ESD STM11.11 section 4.0 REPEATABILITY, This test method has been shown to have a repeatability of approximately one half order of magnitude in controlled environments.
