Megger 6231-601 Digital Loop Tester, For Use With LTW Series

The MFT1500 series has all the essential features necessary for testing Domestic, Commercial and Industrial fixed wiring in accordance with BS7671 and European Standard EN61557. The unique design allows it to be operated on the floor, a ledge, hung around the neck with the supplied neck strap, or held in the hand. The hand strap increases operational comfort and security with all the test functions easily to hand. The backlit display and selector dial allow for use in difficult low-light conditions.

Patented Megger Digital/Analogue Arc display provides both digital readout and indication of fluctuating readings
Fast 200mA continuity test commences the moment the test probes touch the circuit with fast response buzzer enabling time saving, hands free testing
Non-tripping loop impedance test (15mA) provides a 3-wire non-tripping 0.01Ω loop test designed to prevent RCD tripping
High current loop impedance test (25A) provides a fast loop test where no RCD is fitted, or for Ze measurement on the incoming side of an RCD
Prospective fault current ranges (25A test)
DC sensitive RCD test
RCD Ramp test displays the actual trip current on all RCD ranges. Ideal for identifying nuisance tripping RCDs
AC/DC Voltmeter independent of any other test functions, eliminating the need to carry a separate multimeter
Illuminated switch probe for single-handed operation and test status indication. Includes remote test button, bright white LED torch (1500mcd), red/green status LEDs and interchangeable probe tips
Visible and audible safety warnings. If live voltages exist on a circuit during insulation or continuity testing the voltage is displayed on the screen. If this voltage exceeds a safe level, the MFT1502 inhibits further testing and a warning beeper sounds for extra safety
10mA to 1000mA RCD test ranges with both 0° and 180° phase angle
Auto Discharge: Safely discharges system after insulation test preventing accidental shock from a stored charge on a long cable during or after disconnection
Shuttered test lead sockets permit only the correct test lead combinations to be connected for safe testing
Rubber over-moulded case and lid provides a secure comfortable hold, whilst providing maximum protection with IP54 weather proof rating
Dimensions 150 x 85 x 235 HxWxD (mm)

Auto RCD test

Selecting the Auto RCD feature starts the RCD test current cycle of Ix0.5, Ix1 and Ix5. Resetting the tripped RCD automatically continues the test sequence. Test results can be recalled on the MFT1552 once completed

Instruction booklet, 3 wire mains test lead set, mains plug test lead, illuminated switched probe, instrument/document carry case. 8 AA & 1 PP3 alkaline batteries.

Keen to take charge of troubleshooting your electrical circuit? Power up your digital loop tester using this mains test lead from Megger. As it's made up of a 3-pole connector leading to a terminated end, there's no need to worry about the hassle of terminating the conductors yourself. Just plug the ends into compatible ports, and you're ready to go. The unit is designed for use with RCD and loop testers from the LTW range, so it's a handy accessory for multiple tools.

• Built-in strain relief on both ends helps prevent wear and cable damage
• Moulded outer sheath offers insulation for protection against electric shocks

• Repair workshops
• Automotive engineering
• Prototype building
• Measuring instruments
• Medical technology

An RCD monitors the current flow in the circuit and quickly disconnects the power supply if it detects earth leakage current. A loop tester, on the other hand, measures the resistance level of an electrical safety device to ensure it's in proper working condition.
