Megger MFT1741+ Multifunction Tester with EVSE Testing Capability
Please Note: For EVSE testing you will require the Megger adapter EVCA210-UK available here.
Or as a complete kit included with the MFT1741+ available here.
Particularly effective in areas that suffer from high electrical noise, the Megger MFT1741+ provides all the tests needed to complete the necessary electrical certifications for industrial, commercial and domestic fixed wiring installations.
Save time and get non-trip loop testing down to 8 seconds with the MFT1741+’s new Loop Impedance testing technology! This innovative ability also increases the accuracy of results as it prevents the RCD from influencing the total loop impedance value. What’s more, you can measure the degree of confidence in the accuracy of the measured loop impedance, thanks to Megger’s new Confidence Meter measurement analysis (patent pending). This technology uses the digital ARC to indicate the analytical process, then continually monitors and adjusts the measurement when circuit noise is present, resulting in a dramatically improved and repeatable test result.
You can even test electric vehicle charge points with the MFT1741+! It comes with an automatic EV Charge Point RCD test sequence, including the 6 mA DC test*.
Easy-to-use and quick to learn, this instrument has no hidden menus or complicated screens but instead has colour-coded function controls that make range selection simple and speedy. Additionally, it can be operated ambidextrously with dual TEST and LOCK buttons at both sides.
The MFT1741+ is designed for tough environments, with IP54 protection against dust and water and an EN61010 CATIV safety rating. Indeed, the MFT can withstand accidental misuse and voltage transients, keeping you safe on the job.
Megger MFT1741+ Comes Supplied With:
- Printed quick start guide
- Full user guide on CD
- Calibration certificate
- Switched probe SP5
- Neck strap - Megger embroidered
- 3 Wire lead set with prods and clips
- Mains plug test lead (BS1363)
- AC battery charger
- Large soft pouch with extra storage
*Important Calibration Information:
This instrument comes complete with the manufacturer's calibration certificate. Please be aware that these certificates are generic and may also be time lapsed.
If you would prefer a personalised full traceable calibration certificate applied to the equipment before dispatch, then please select this option from the drop-down menu above, an additional calibration charge will apply.
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
- Testing of Electric Vehicle Charge Points*
- Enhanced non-trip loop impedance measurement technology

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

Prospective fault current measurement up to 20 kA
- RCD testing including:
Type ac, A, S, B and programmable RCDs
Testing of Electric Vehicle Charge Points RCD’s*
EV Charge Point RCD Testing
- Earth spike testing
2-pole/3-pole*, ART* and Stake-less* techniques
* With appropriate optional accessories
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.
New electric vehicle charge point testing
The MFT1741+ includes an automatic EV Charge Point RCD test sequence, including the 6 mA dc test*.
Test results can be reviewed or saved to memory and reviewed later.
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.

Delivery Notices (Updated March 29th 2021)
During the current situation surrounding the effects of the Coronavirus pandemic, logistics from every company are under immense pressure to deliver goods on time.
Coupled with manufacturers on reduced output due to more stringent working practices and a global shortage of component parts to supply UK manufacturing, we have taken the decision to temporarily limit our services rather than let our customers down amid these unprecedented circumstances.
We hope you will understand our position on this and we apologize unreservedly for the inconvenience we know it will cause.
Please note that ALL orders placed before 3:00pm are shipped same-day (subject to stock and any additional services required).
The stated transport times above have some scope for adjustment built-in for the Covid-19 situation. Carriers themselves also have their own extended workload and limitations at this time which are unfortunately beyond our control.
Orders requiring calibration
Whilst we take the greatest care to get all orders dispatched and delivered to you in the stated time frame, orders received PM and requiring
calibration may on occasion miss dispatch that day, according to the complexity of the calibration. Be assured they will ship on the next dispatch
this in most cases should not add more than 24 hours to your delivery.
Predicted delivery times are based on regular trading days Monday to Friday. Public holidays, bank holidays and weekends are outside the usual scope
of our dispatch and subject to activities/holidays of our carriers and therefore may incur additional days lead time to your order.
