Megger 1003-132 Test Lead Kit, CAT IV, 10A

LTW425

The Megger LTW425 two wire earth loop tester verifies the loop impedance of a live electrical circuit, ie without the need to disconnect the electrical supply. 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.

High resolution (0.001Ω) 2 wire testing + maxZ + (R1+R2)
Backlit display
2 wire loop tests: Phase to Earth, Phase to Neutral or Phase to Phase
3 phase circuits with RCD protection can be tested
Tests radial circuits where the circuit does not return to the origin, even where only a phase and neutral contacts are available.
10 second non trip loop test time with Auto test extension up to a further 10 seconds if noise is detected, to improve the accuracy of the test
High current loop testing for supplies that do not have an RCD fitted
AUTO START will start the loop test running as soon as the test leads are connected; No need to press the test button means much safer testing
PFC Display up to 40kA
Voltage and frequency measurement
110 Vac systems including 110V centre tap to earth (55 V phase to earth) can be tested on the secondary winding.
IP54 Weatherproof case
Optional 10A fused 2 wired test leads and crocodile clip set
Complies with IEC61010-1 300V CATIV safety standard and meets EN61557

Supplied with

Test lead set with crocodile clips, mains socket test lead, 8 AA alkaline batteries, hard carry case and instructions.
