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 LTW300 series
instruments offer a 2 wire loop testing solution that does
not trip 30 mA RCDs and can be used on a wide range of
voltages.

The new LTW300’s offer a range of features to make earth loop testing safer and easier.

The range consists of:

• LTW315 - 2 Wire loop impedance measurement
• LTW325 - 2 wire + maxZ + (R1+R2)
• LTW335 - 2 wire + maxZ + (R1+R2) + Download

• 2 Wire Non-tripping loop tester
• 50 V to 440 V operation
• 110 V centre-tap loop testing
• CATIV installation testing
• AUTO start - operation
• 0.01 Ω resolution
