Megger MFT1735 Multifunction Tester

MFT1735 designed for testing low voltage electrical installations to BS 7671. It provides all the tests required to complete the necessary electrical certification for industrial, commercial and domestic fixed wiring installations. Supplied with rechargeable batteries and earth spike set.


*Important Calibration Information:

This instrument comes complete with a manufacturers 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.

Megger MFT1735 Comes Supplied With:

  • Printed quick start guide Full user guide on CD 
  • Calibration certificate 
  • Switched probe SP5 (not with MFT1710) 
  • 1002-774 Neck strap - Megger embroidered 2001-509 
  • 3 Wire lead set with prods and clips 
  • 1001-991 SIA10 Socket interface adaptor UK to 3 x 4 mm (BS) 
  • 6220-810 SIA20 Socket interface adaptor UK to 3 x 4 mm (AU) 
  • 6220-828 Plug-in battery charger 2001-697. 
  • Rechargeable Batteries 
  • Earth spike set.


The MFT1700 series is a range of 3 instruments for testing low voltage electrical installations to BS7671. They provide all the tests required to complete the necessary electrical certification for industrial, commercial and domestic fixed wiring installations. 

The unique modern styling allows it to be operated while stood on the floor, a ladder-shelf or platform, hung around the neck or handheld. Dual TEST and LOCK buttons – one pair at each end – makes the testers easy to operate left or right handed. 

Quick to pick up and use, the 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 patented 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 MFT1700 series 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 MFT1730 features internally rechargeable batteries and charger with a charge time of less than 4 hrs, so reducing the cost of ownership. Fully compliant with all requirements of IEC 60364 derived standards including VDE 0100 and BS 7671, the new MFT includes all the latest measurement technology in a lightweight


Key Features:

  • Two wire non trip loop testing for fast repeatable results

  • On-board data storage and Bluetooth® download

  • 3-terminal earth test for electrode resistance measurement

  • 3-phase RCD testing for industrial applications with no earth

  • Phase rotation indication for verification of rotating machinery

  • Large bright LCD display showing dual parameters - loop resistance and fault current, insulation resistance and test voltage

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.

Bank/Public Holidays

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.
