DESCRIPTION
The MFT1800 range consists of 3 instruments designed for testing
low voltage electrical installations to IEC 60364. They provide all
the tests required to complete the necessary electrical certification
for industrial, commercial and domestic fixed wiring installations,
including:
 System voltage and frequency measurement (TRMS)*.
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
 Continuity resistance at 200 mA or 15 mA*
Automatic - no need to press TEST so leaving both hands
free to hold probes.
 Resistance range up to 100 kΩ
With fast continuity buzzer and selectable thresholds
 Non-trip loop test
Earth loop test
2 and 3 wire non-trip range
2 wire Hi current including phase to phase
 Prospective fault current measurement
Up to 20 kA
 RCD testing including:
Type AC, A, S, B* and programmable RCDs 1/2 x I, 1 x I,
2 x I and 5 x I
3-phase RCDs*
Fast ramp test
Auto-test routine
Fault (Touch) voltage display
 Earth testing
2-pole,
3-pole

Stakeless techniques
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 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 hand-
held. Dual TEST and LOCK buttons - one pair at each end - make
the testers easy to operate with either the left or right hand.
Quick to pick up and use, the rotary 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 MFT1800 range 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 MFT1835 features internally rechargeable batteries and charger
with a charge time of less than 4 hrs, so reducing the cost of
ownership
