MFT1711, MFT1721, MFT1731 and MFT1741
Multifunction Tester
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 MFT1701 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 MFT1731 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 light-weight compact design, fully
protected and usable on single phase and 3 phase installations.
Key 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 and stakeless
clamp techniques for earth electrode testing.
The MFT1731 and MFT1741 includes built in memory and Bluetooth
®
communications for downloading test results using Megger
Download Manager (supplied).
The new MFT1701 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 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
MFT1711 and MFT1721 are supplied in a robust moulded case, and
the MFT1731 and MFT1741 is supplied in a large soft pouch 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.
