Hello Deep; Whenever you see some mention of CATx or Level yy in promotional or technical documents you can be sure this refers to a national or international standard. In the case you are mentionning, the manufacturers refer to standard IEC 61010-2. For example: http://www.megger.com/common/documents/MIT400Combo_DS_en_US_04.pdf The MIT400 Series instruments are designed to meet all of the requirements of IEC1010-2 and E55N617 and meets the safety requirements for use on CAT IV 600 V. Specific safety features include: - Any live circuit detection inhibits any insulation testing on circuits above 50 V (75 volts on Telecom models) - Any live circuit detection and test inhibit on continuity measurements- Default display of live circuit voltage on all ranges - Detection and inhibit features function even if the protections fuse has failed Also, fast detection circuitry prevents damage to the instruments if accidentally connected to live circuits or across phases. IEC1010-2 information is available on purchase of the standard, and not much detail is available for free..Hereare some of the elements that can be found on the web: http://www.ul.com/global/eng/pages/offerings/industries/healthsciences/services/ul61010/ http://www.pdftop.com/ebook/iec+61010+1/ Hope this helps, Daniel Chartier |
