We are preparing to purchase several Associated Research Quadcheck II, highpot, ground bond, and insulation resistance testers. I've run across an issue pertaining to a 500 VA requirement for highpot in EN 60204, which this "All-in-one" tester is not capable of producing. According to the manufacturer, the instrument shortcomings, as they pertain to 500VA, have been eliminated as a result of microprocessor controlled power supplies. I believe this unit only produces upwards of 300 VA. The cost of this unit is reasonable and it is very friendly to operate in a production environment. (no I'm not a distributor or sales person for this product).
My questions: Should I purchase this unit, test our products, and hope the 500VA requirement in 60204 will change in the future due to the advancements in these testers? (we are self certifying our equipment to the Machinery Directive) or Should I find a unit that performs the test at 500 VA? Thanks in advance....
