The HYAMP® III model 3140 mid range ground bond tester is designed to provide up to 40 Amps of ground bond test current continuous duty. It was designed to accommodate for revisions made to both the CSA-C22.2 NO. 60950-1-03 and the UL 60950-1 standards for information technology equipment. The revisions now require ground bond test current to be 2 times the current rating of the circuit under test. Previously these standards only required the test current to be 1.5 times the current rating. The 3140 features a new enhanced graphic LCD that allows critical information to be viewed more prominently by the operator. It simplifies the user interface and allows users to quickly and effortlessly set-up tests, perform tests, and read results.
