The Megger MFT1735 is 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.
The range of earth electrode tests supplied on-board the Megger MFT1735 makes it the perfect test package for those working on TT installations, vehicle charging point installations and verifying the earthing performance of lightning protection systems.
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.
** The MFT1735 is supplied with a 3-wire earth test kit, however optional accessories are required for the ART and stakeless techniques.
FEATURES
Two and three wire non-trip loop testing for RCD protected circuits.
Type-B RCD and 3-phase RCD testing for industrial applications with no Earth.
3-terminal earth test and stakeless testing for earth electrode resistance measurement **
Internal memory and Bluetooth® communications.
Simple colour-coded test selection and large clear back-lit display for ease of use.
EN61010 CATIV safety ratings and tough IP54 case.
