N-E | N-E | LED is light when P and N are reversed or the Earth is not connected |
15mA Loop measurement | Loop impedance 2000Ω range measurement is carried out with low test current (15mA). The current will not cause tripping out for ELCBs | |
Over Temperature Protection | When over heating, the ‘thermometer’ symbol will show on LCD & instrument will stop measuring | |
