Made in AmericaWrist Strap Range: 750 Kilohms - 10 Megohms Footwear Range: 750 Kilohms - 100 Megohms
Per ESD Handbook TR 20.20 paragraph 5.3.2.4.4 "Typical test programs recommend that wrist straps that are used daily should be tested daily. However, if the products that are being produced are of such value that knowledge of a continuous, reliable ground is needed, and then continuous monitoring should be considered or even required."

“Compliance verification should be performed prior to each use (daily, shift change, etc.). The accumulation of insulative materials may increase the foot grounder system resistance. If foot grounders are worn outside the ESD protected area testing for functionality before reentry to the ESD protected area should be considered.” (ESD SP9.2 APPENDIX B - Foot Grounder Usage Guidance)
“A log should be maintained which verifies that personnel have tested their personal grounding devices.” (ANSI/ESD S20.20 Paragraph 6.2.2.2 Personnel Grounding Guidance)
“Frequency of Functional Testing: The wrist strap system should be tested daily to ensure proper electrical value. Nominally, the upper resistance reading should be < or = 10 megohms or a user-defined value.” (ANSI/ESD S1.1-2006 Annex A3)
