Bought to test my grounding/grounding gear and show friends the difference between not being grounded and being grounded. That works great! I briefly thought it was broken when the OL icon appeared, but after reading the instructions I realized I was just overloading it with the settings I had. Changed to a higher value and all is well. It has the lowest setting you need to test grounding devices, millivolts.
