Description of the problem

The primary function of the SM100, SM200, and SM300 Socket Testers is to detect the presence of an open ground in a socket outlet. Socket outlets are often installed in metal boxes and have exposed metal parts connected to the earth pin of the socket.

If the Socket Tester detects a missing earth condition, shown on the tester as ○○, the internal circuitry will source a voltage from the phase conductor onto the earth pin of the socket outlet, as well as any metal parts connected to the earth pin of the socket.

Such a condition can result in an electric shock to the user. The current level is probably not life threatening in most cases but could be painful and may be sufficient to knock a person down or off a ladder.
