產品詳細資訊
Megger Loop Impedance Tester
The Megger earth loop impedance testers are 2-wire, 440V and ±10% test loop accuracy. This tester is to verify the loop impedance of a live electrical circuit without the need to disconnect the electrical supply. The LTW300 series instruments offer a safe and easy but do not trip 30mA RCDs and can be used on a wide range of voltages. A loop test is performed with only 2 test leads. This can be either phase to earth, phase to neutral and phase to phase.
Supplied with
Test lead set with crocodile clips, mains socket test lead, 8 AA alkaline batteries, hard carry case and instructions.

Features and Benefits
Backlit display
0.01Ω resolution
No-trip loop test on circuits with RCDs of ≥30 mA
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.
10second non-trip loop test time with autotest extension up to a further 10seconds
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 20kA
Voltage and frequency measurement
110Vac systems including 110V centre tap to earth (55V phase to earth) can be tested on the secondary winding.
Optional 10A fused 2 wired test leads and crocodile clip set
