Megger MFT70-US – Multifunction Tester

The Megger MFT70 Multifunction Tester is designed for testing low voltage electrical installations to fulfill the requirements of NFPA70 and the National Electrical Code. It provides all the tests required to complete the necessary electrical certification for industrial, commercial and domestic fixed wiring installations, including:
 

This instrument is IEC 61010 CAT IV 300 V rated for connection to low voltage systems with no protective device, so it is safe for connection anywhere on the system up to the source transformer without risk of damage from large transient spikes.

 

The unique modern styling allows it to be operated while standing on the floor, a ladder-shelf or platform, hung around the neck or handheld. Dual TEST and LOCK buttons one pair at each end make the tester easy to operate with either the left or right hand.

 

Easy to pick up and use, the rotary controls are color coded to make range selection fast. They also reduce the chance of using the wrong function or range. The large crystal clear backlit display uses the patented Megger digital/analog arc, providing an indication of fluctuating readings. The dual digital readout shows precise values of key measurements  and the test parameters simultaneously, 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 MFT70 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 MFT70 features internally rechargeable batteries with a charge time of less than 4 hours, which reduces the cost of ownership.

 

Fully compliant with all requirements of IEC60364 derived standards, the MFT70 includes all the latest measurement technology in a lightweight compact design and is fully protected and usable on single phase and three phase installations

 

The MFT70 combines quick continuity resistance with a number of insulation resistance tests as well as testing of GFCIs, alleviating the need for multiple separate function test instruments.

 

The unit includes built in memory and Bluetooth communications for downloading of memory using Megger Download Manager (supplied) for simple form filling of test results.

 

The MFT70 is designed for tough environments and ultimate reliability. Features include a rubber over mold for extra protection and grip, IP54 protection against dust and water and an IEC61010 CAT IV safety rating. Its class leading input protection ensures the MFT70 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. Tests are easily selected using the color coded rotary switches with results clearly displayed on the high contrast dual measurement backlit display.
