Megger LTW315 Loop Tester

The Megger LTW315 is a non trip and high current loop tester designed for the domestic market. The LTW315 offers a 2 wire loop testing solution that does not trip 30mA RCDs and can be used on a wide range of voltages. When carrying out no-trip testing procedures the Megger LTW315 constantly evaluates the level of noise detected on circuitry to ensure that the accuracy of results is not modified by the presence of electrical noise Featuring an auto start operation, and capable of 110V centre tapped loop testing, making this great value for money. The thick rubber casing protects from damage and the clear LCD display makes it easy to read. FEATURES 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.
