Megger MFT70 Multifunction Electrical Installation Tester
Megger MFT70 Multifunction Electrical Installation Tester
The 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:
Multifunction Testing Includes:
- System Voltage and Frequency Measurement True RMS
- Phase Rotation (L1; L2; L3 or L1; L3; L2)
- Continuity test 200mA or 15 mA (default is set to 200mA, change in SETUP)
- Insulation testing 100V, 250V, 500V & 1000V test ranges are available. Complaint test voltage is maintained down to 0.5Mohms.
- GFCI Testing The MFT70 can perform a ramp test on a 6mA GFCI to ensure it trips under fault conditions. This GFCI test meets the requirements of GFCI Type A as defined in the ANSI/UL 943, CSA C22.2 No. 144.1 and ANCE NMX-J-520.
- Ground Testing • 2-pole • 3-pole • ART • Stakeless techniques
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 highenergy 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.
