DESCRIPTION
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, including:
n
System voltage and frequency measurement (TRMS)*
n
Insulation test at 100 V*, 250 V, 500 V and 1000 V*
Including input protection against live circuits up to
600 V even when insulation test is locked-on
n
Continuity resistance at 200 mA or 15 mA*
Automatic start – no need to press TEST so leaving both
hands free to hold probes
n
Resistance range up to 100 kΩ
With fast continuity buzzer at selectable thresholds
n
2-wire loop test
Non-trip (RCD) and high-current testing
Including Phase-to-Phase
n
Prospective fault current measurement
Up to 20 kA
n
RCD testing including:
Type AC, A, S, B* and programmable RCDs
3-phase RCDs*
Auto-test routine
Fault (Touch) voltage display
n
3-pole earth testing
All instruments are IEC 61010 CAT IV 300 V rated for
connection to low voltage systems with no protective device,
so safe for connection anywhere on the system right up to
the source transformer without risk of damage from large
transient spikes.
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 compact design, fully protected and usable on single
phase and 3 phase installations.
New measurement functions include two and three wire
non-trip loop test technology for fast repeatable results,
comprehensive testing of RCDs including type B, and
integrated 3-terminal techniques for earth electrode testing.

Multifunction Tester
The MFT1730 includes built in memory and Bluetooth
communications for downloading test results using Megger
Download Manager (supplied). As an option, the MFT1730
is available complete with PowerSuite® Lite combined with
Ultra Mobile software as the MFT1730 On-Site. PowerSuite
provides a professional solution to certification with electronic
form completion from stored data within the MFT, either
downloaded to a mobile device such as a Smartphone,
or direct to a PC. See the separate datasheet on Megger
PowerSuite software for further details.
The new MFT1700 series has been designed for tough
environments and ultimate reliability. Features include
a rubber over mould for extra protection and grip, IP54
protection against dust and water and an EN61010 Cat IV
safety rating. Its class leading input protection ensures
the new MFT 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 colour coded rotary switches with results
clearly displayed on the high contrast, dual measurement,
backlit display.
Included with the instrument:
standard 3-wire leadset and a mains test lead, a switched
probe for fast and easy testing*, a full 12-month calibration
certificate and warranty upgradeable to 3 years. The MFT is
supplied in a robust moulded case with plenty of additional
space for optional extras like a few tools and the earth
electrode test kit, comprising 2 spikes and 3 long test leads.
