Megger MFT1735 Multifunction Installation Tester with Bluetooth

The Megger MFT1735 Multifunction Installation Tester has been designed to test 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.

With IEC 61010 CAT IV 300 V rating for connection to low voltage systems with no protective device, so safe for connection anywhere on the system up to the source transformer without risk of damage from large transient spikes.  The MFT1735 casing allows it to be operated while stood on the floor, a ladder-shelf or platform, hung around the neck or hand-held. Dual TEST and LOCK buttons – one pair at each end – make the testers easy to operate with either the left or right hand.  Quick to pick up and use, the rotary 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.


Megger 1735 Key Features:

  • Simple colour-coded test selection and large clear backlit display for ease of use
  • Two and three wire non-trip loop testing for RCD protected circuits
  • Internal memory and Bluetooth communications
  • Type-B RCD and 3-phase RCD testing for industrial applications with no Earth
  • 3-terminal earth test and stakeless testing for spike resistance measurement
    • Supplied with a 3-wire earth test kit, however optional accessories are required for the ART and stakeless techniques
  • EN61010 CATIV safety ratings and tough IP54 case


Megger 1735 Applications:

  • System voltage and frequency measurement (TRMS)
