Outlet Tester

[2gsg2_muc]

Hi guys, there is a tester for regular outlets with easy readout. When it shows a green triangle, the outlet Line is connected to the right side the Neutral to the left and the ground connection is ok. When one of the LED schows blue instead of green the conction Line and Neutral is reversed. Any redlight schows a serious problem.
