Megger MFT1741 Multifunction Tester

 

The MFT1741 multifunction tester has been designed for testing low voltage electrical installations, particularly in locations that suffer from high electrical noise. It provides all the tests required to complete the necessary electrical certification for industrial, commercial and domestic fixed wiring installations.

Overlaying the new non-trip loop impedance measurement is the new “confidence meter”. As loop impedance values can be dramatically affected by circuit noise, the Confidence Meter displays the degree of confidence in the accuracy of the measured loop impedance. Using the digital ARC to indicate the analytical process, the measurement is continually monitored and adjusted when circuit noise is present, resulting in a dramatically improved and repeatable test result.

The MFT1741 offers a wide range of test functions, designed for all electrical installation testing and verification of low voltage building wiring and distribution testing scenarios. The MFT1741 is IEC 61010 CAT IV 300 V rated for safe connection anywhere within the LV network on single and three-phase systems.

 

Megger MFT1741 Comes Supplied With:

  • Megger MFT1741 Multifunction Tester 1009-986
  • 3 wire test lead set with probes and crocodile clips
  • Mains plug test lead
  • Rechargeable batteries and charger
  • Switched test probe for remote testing
  • Megger embroidered Neck strap
  • Carry case
  • Full user guide CD for MFT1741
  • Megger calibration certificate
 
 
The MFT1741 multifunction tester is an instrument designed for testing low voltage electrical installations and especially in locations that suffer from high electrical noise. It provides all the tests required to complete the necessary electrical certification for industrial, commercial and domestic fixed wiring installations, and includes:
  • TRMS System voltage and frequency measurement 
  • Insulation test at 100 V, 250 V, 500 V and 1000 V Including input protection against live circuits up to 600 V even when insulation test is locked-on
  • Continuity resistance at 200 mA or 15 mA
  • Automatic start - no need to press TEST so leaving both hands free to hold probes 
  • Resistance range up to 100 kΩ with fast continuity buzzer at selectable thresholds 
  • Earth loop impedance testing, with:
    • New 3 wire non-trip technology
    • New confidence meter measurement
    • 2 and 3 wire non-trip range
    • 2 wire Hi current including phase to phase

* with appropriate optional accessories
 
 

Key Features:

  • Enhanced non-trip loop impedance measurement technology 
  • “Confidence meter” measurement analysis (patent pending) 
  • Full single and 3 phase compliant installation testing 
  • 10 mA to 1 A single and 3 phase RCD testing 
  • Earth testing and stake-less testing for electrode resistance measurement* 
  • Simple colour-coded test selection 
  • Ambidextrous operation
  • Internal memory and Bluetooth® communications
  • EN61010 CAT IV safety rating and tough IP54 case
 

New Loop Impedance testing technology

The MFT1741 includes a new non-trip loop testing technology that :
  • Prevents any influence the RCD may present to the total loop impedance value. 
  • Faster non-trip loop testing down to 8 seconds. This technique also allows testing of loop impedance through 10mA type AC and Type A RCDs. 


New “Confidence meter*” measurement analysis (Patent pending)

 
Overlaying the new non-trip loop impedance measurement is the new Megger “Confidence meter”. As loop impedance values can be dramatically affected by circuit noise, the Confidence Meter displays the degree of confidence in the accuracy of the measured loop impedance. Using the digital ARC to indicate the analytical process, the measurement is continually monitored and adjusted when circuit noise is present, resulting in a dramatically improved and repeatable test result.
 
 

Key Applications:

 
The MFT1741 offers a wide range of test functions, designed for all electrical installation testing and verification of low voltage building wiring and distribution testing scenarios. The MFT1741 is IEC 61010 CAT IV 300 V rated for safe connection anywhere within the LV network on single and 3 phase systems.
 
The unique modern styling allows it to be operated while stood on the floor, whilst up a ladder or platform, and optimised for hanging around the user’s neck. Dual TEST and LOCK buttons - one pair at each end - makes the testers easy to operate left or right handed. General features: Quick to pick up and use, the function controls are colour coded to make range selection easy and fast. They also reduce the chance of using the wrong function or range.
 
The large crystal clear backlit display uses the Megger digital/analogue arc, providing indication of fluctuating readings while the dual digital readout shows precise values of key measurements simultaneously with the test parameters, such as the output voltage on insulation testing as well as the resistance value in MΩ. Visible and audible safety warnings are paramount when testing high-energy systems and the MFT1741 includes full input protection and safety warnings when a hazardous voltage is present. 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, further testing is inhibited and a warning beep sounds. The MFT1741 features internally rechargeable batteries and charger with a charge time of less than 4 hrs, so reducing the cost of ownership.
 
The new MFT1741 has been designed for tough environments and ultimate reliability. Features include a rubber over mould for extra protection and grip, IP54 protection against dust and water and an EN61010 Cat IV safety rating. Its class leading input protection ensures the MFT can withstand accidental misuse and voltage transients when other testers can’t. All this in an intuitive and easy to use instrument with no hidden menus or complicated screens. Included with the instrument: standard 3-wire lead-set and a mains test lead, a switched probe for fast and easy testing, a full 12-month calibration certificate and warranty upgradeable to 3 years warranty, free of charge.
 
The MFT1741 is supplied in a large soft pouch with plenty of additional space for optional extras like a few tools and the earth electrode test kit, comprising 2 spikes and 3 long test leads.
