【Singapore】 When measuring loop impedance of EVSE by using multifunction tester and EVSE adapter, built-in RDC-DD (6 mA) trips sometimes. So I need to bypass the RDC-DD, that is extra time-consuming work.

【Australia】 It took two persons seven hours to determine that the cause of the RCD tripping in the field was a N-E reverse connection. Existing socket testers could not find the N-E reverse connection.

【Indonesia】 Multiple testers are required to check the power of a busbar (80x10 mm) or in cable crowded area. I've been worried about touching with a busbar adjacent to the cable I wish to clamp.
