Grounding tester for measuring ground loop resistance and leakage current. This device measures discharge, leakage and load current via the TRUE RMS measurement method and no separation of grounding or placement of spikes/probes is required during measurements. Because of the True RMS measurement system, the loads of non-linear wave patterns are also measured, not just the linear patterns. As a result, the correct value is always displayed and failures or damages can be prevented. The clamp-on probe has an optical and audible alarm function in case of excessive ground resistance and a large measurement value memory. Show more
