Access control to an ESD of insulative materials may increase the foot grounder Protected Area can be further enforced by using the system resistance. If foot grounders are worn outside relay terminal on the Dual Combination Tester and the ESD protected area testing for functionality connecting it to an electronic door lock or turnstile before reentry to the ESD protected area should be to grant access only to those who have passed their considered. (ESD SP9.2 APPENDIX B - Foot Grounder personal grounding device tests. The Dual Combination Usage Guidance) Tester is calibrated to NIST standards and includes a certificate. SCS Dual Combination Tester Technology The solid-state touch test switch maintains test accuracy and extends the lifetime of the tester The 30 volt test signal increases test reliability The factory test limits are set to: Wrist Straps: 750 kilohms and 10 megohms Footwear: 750 kilohms and 35 megohms (See page 3 for alternate test limit settings) 1. The Dual Combination Tester can verify single-wire and dual-wire wrist straps. 2. The Dual Combination Tester will also test a Groundable Static Control Garment System. The Groundable Static Control Garment System must have an RTG of < 3.5 x 10 ohms to meet the required limit of ANSI/ESD S20.20 tested per ANSI/ESD STM2.1 and ESD TR53.
