The new Megger two wire earth loop testers verify the loop impedance of a live electrical circuit, ie without the need to disconnect the electrical supply.
The new LTW425 series instruments offers a high resolution 2-wire loop testing solution that does not trip 30 mA RCDs and can be used on a wide range of voltages.
Function:
2 Wire Non-tripping loop tester, 50 V to 440 V operation, 110 V centre-tap loop testing, CATIV installation testing , AUTO start – operation , 0.001 Ω resolution.
