Megger LTW325 Loop Impedance Tester

The Megger LTW325 Loop Impedance Tester is a two-wire plus maxZ + (R1+R2) earth loop tester which verifies the loop impedance of a live electrical circuit, i.e. without the need to disconnect the electrical supply.

The Megger LTW325 Loop Impedance Tester uses a 2-wire loop testing solution that does not trip 30 mA RCDs.

The Megger LTW325 Loop Impedance Tester will operate on a wide range of voltages from 50 V AC to 300 V AC single phase supplies and up to 440V AC on 3 phase installations.  This includes centre tapped 110 V AC circuits, with 55 V phase to earth.

A loop test is performed with only 2 test leads. This can be either:

• Phase to Earth
• Phase to Neutral
• Phase to Phase

Testing is simple, as there is no need for a 3rd wire to be connected, which can cause confusion when trying to identify which part of the circuit is being tested.

Megger LTW325 Loop Impedance Tester features:

• 2 Wire Non-tripping loop testing
• 2 Wire fast test (high current)
• 50 V to 440 V applications
• Phase to phase testing
• 20 kA PFC
• CATIV installation testing
• AUTO start loop
• AUTO noise detection
• Voltage measurement
• Frequency measurement
• 0.01 Ω resolution
• Max Zs display
• R1 + R2 display

Megger LTW325 Loop Impedance Tester comes complete with a calibration Certificate Traceable to National Standards when purchased new.
