Description

Megger MFT1741+ PLUS Multifunction Tester 18th Edition Compliant

Product Details:

The Megger MFT1741+ Multifunction Tester is suitable for conducting full single- and three-phase insulation testing. As indicated above it is able to conduct single- and three-phase RCD testing between 10mA and 1A.

The Megger MFT1741+ Multifunction Tester’s NEW non-trip loop impedance testing technology also enables loop impedance testing of 10mA type AC and A RCDs. Additionally, NEW non-trip loop impedance technology prevents RCDs from influencing the total loop impedance value and increases the speed of testing: non-trip loop impedance tests can be performed in eight seconds.

Furthermore, loop impedance tests are accompanied by a Confidence Meter, a NEW feature present on the Megger MFT1741+ Multifunction Tester. The meter will indicate the degree of confidence in the accuracy of the loop impedance measurement. This feature is useful as loop impedance values are particularly susceptible to changes in circuit noise. The Confidence Meter is designed to improve reliability; the digital ARC indicates the analytical process, and the measurement is continually monitored and adjusted in reference to the circuit noise.

Key Features:

  • Troubleshooting and Verification: This tester is suitable for verifying the installation and safety of industrial, commercial, and fixed wiring installations.
  • Electrical Certification: It includes all the necessary tests required to complete electrical certification for different types of electrical systems.
  • Noise Resistance: Ideal for testing low voltage electrical installations in areas with high electrical noise, ensuring accurate measurements.
  • Insulation Testing: Capable of conducting full single- and three-phase compliant insulation testing, ensuring the integrity of electrical insulation.
  • RCD Testing: It can perform single- and three-phase RCD (Residual Current Device) testing between 10mA and 1A, essential for safety checks.
  • Non-Trip Loop Impedance Testing: The tester features non-trip loop impedance technology, enabling quick testing of 10mA type AC and A RCDs. It prevents RCDs from influencing total loop impedance values and provides results in as little as eight seconds.
  • Confidence Meter: The Confidence Meter indicates the reliability of loop impedance measurements, considering circuit noise. It ensures accurate and dependable results.
  • EVSE RCD Testing: It can test electric vehicle charge point RCDs with automatic test sequences and offers a 6mA DC test (requires an optional accessory).
  • Display: The tester has a large, clear backlit display with digital/analog arcs for indicating fluctuating readings and a dual digital readout for precise readings and test parameters.
  • Memory: It has an internal memory with a capacity for storing up to 1000 readings. These results can be downloaded via Bluetooth for documentation and analysis.
  • Ease of Use: The tester features color-coded function controls for easy access to measurement functions and ranges, reducing the risk of selecting incorrect settings. It does not have complicated or hidden menus.
  • Ambidextrous Design: It has dual TEST and LOCK buttons on both sides of the unit, making it suitable for both right- and left-handed users.
  • Automatic Test Start: This function eliminates the need to press the TEST button, making it convenient for users while holding probes or working on a ladder.
  • Portability: The tester can stand independently or be hung around the operator’s neck using the included neck strap.
  • Battery: It comes with internal rechargeable batteries that can be fully charged in under four hours, maximizing uptime.
  • Durability: The rubber over-mold provides additional protection in tough environments, and it has an IP54 rating for resistance to dust and water ingress.
  • Safety: The tester is EN61010 CAT IV safety rated, capable of withstanding accidental misuse and voltage transients. It can be connected anywhere within the low voltage network on single and three-phase systems.
  • Safety Warnings: It provides visual and audible warnings when hazardous voltages are detected during testing, enhancing user safety.
  • Versatility: The Megger MFT1741+ is suitable for various electrical parameters, including electrical installation and verification applications in low voltage building wiring and distribution testing scenarios.
