Testing for dangerous small leakage currents is easy with the Simpson Model 229-2 Leakage Current Tester. For use in appliance field service, in the lab, or in production, the 229-2 approximates the human threshold of perception in detecting hazardous AC leakage current. The 229-2 comes with test leads with alligator clips, manual and batteries. Checks both 120VAC and 240VAC appliances, motors and other equipment Conforms to ANSI C101.1-1986 and UL safety standards Overload protected up to 500V peak momentarily on all ranges Compensated to approximate Dalziel'''s threshold of perception curve
