MFT1845
Multifunction Tester
General features:
Quick to pick up and use, the function 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 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 MFT1845 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
MFT1845 features internally rechargeable batteries and charger
with a charge time of less than 4 hrs, so reducing the cost of
ownership.
The new MFT1845 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.
Included with the instrument: standard 3-wire lead-set 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 warranty free of charge. The MFT1845 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.
