MIT200 Series
Digital/Analog Insulation and Continuity
Testers
DESCRIPTION
The MIT200 is one of the smallest insulation testers available
on the market today. With options of one, two and three
voltage test voltage instruments, the MIT200 instr uments
offer a range of safety and operation features.
The display offers a combination of digital readout and
analog display, using Megger’s patented DART display
technology, which includes the benefits of an LCD display,
such as robust, clear and accurate measurement, with an
analog pointer response for evaluating circuit charge and
discharge characteristics.
The instrument housing is in tough AB S, designed to with-
stand the rigours of hard use, and is small enough to drop
into your pocket when not in use.
Batteryrequirements are 6 AA batteries of either standard
alkaline or nickel metal hydride (NiMH) rechargeable type. A
low battery war ning indicator gives advanced war ning of
exhausted batteries.
Continuity testing
Automatic continuity testing is performed at 200 mA to
ensure compliance with international requirements. There is
no need to press the test button.
All instruments will measure up to 100 Ωon continuity, of
which 0-10 Ωis perfor med at greater than 200 mA to meet
international electrical testing requirements.
Lead null is possible up to 9.99 Ωof test lead resistance,
ensuring the ability to null fused test leads as well as |
standard leads.
Continuity buzzer
Acontinuity buzzer provides a means of rapid cable testing
and circuit identification, with voltage protection should you
accidentally touch a live circuit.
The buzzer operates at a 2 Ωthreshold.
Insulation testing
The instruments offer four configurations as detailed on
page 2, providing an ideal solution to most low voltage
insulation testing applications.
Insulation testing is possible up to 1000 MΩon all ranges.
Auto discharge ensures all circuits are safely discharged after
testing.
1000 V insulation test ranges have a high voltage warning
prior to test voltage being applied.

FEATURES AND BENEFITS SUMMARY
nMeets the international EN61557 requirements of the
rated test voltage into a 1 mA load.
nDigital display of insulation measurement up to
1000 MΩon a logarithmic analogue arc and a digital
display.
nContinuity range has 0,01 Ωresolution and a short circuit
current in excess of 200 mA.
nAutomatic continuity testing leaves both hands free. No
need to press the test button.
nAutomatic power-off if lef t unattended reduced wasted
battery life.
nAutomatic voltage detection avoids accidental contact
with live circuits.
nTest lead zero allows compensation for test lead
resistance.
nBuzzer range operates at <2 Ω.
Safety
Every Megger instr ument is designed with safety as its
primary objective. All instr uments meet or exceed the
requirements of safety directive IEC 61010 and EN61557 for
insulation and continuity testing..
Default fault meter
Abuilt-in voltmeter automatically switches in when the
instrument is connected to a circuit with an AC or DC
voltage greater than 25 V.
Insulation Test inhibit
Circuits in excess of 25 V will generate a voltage warning.
Circuits over 50 V will inhibit testing of the insulation,
protecting the operator and the instrument from injur y or
damage.
600V CATIII
The MIT200 series has been designed for use on
applications up to 600 V CATIII.
APPLICATIONS
The MIT200 series will find applications in electrical
contracting, both on domestic and industrial systems, as
well as site maintenance and service depar tments.
The MIT200 series of insulation and continuity testers are
ideal for testing transformers, motors, generators
switchgear, panel building, domestic appliances, power
tools etc., as well as fixed electrical wiring systems.
Their small size and light weight make them ideal for those
engineers that need to carr y them for extended periods.
All instruments meet the requirements of most
International Standards including VDE0413 Part 1 and
BS7671 (the 16th Edition of the IEE Wiring Regulations).
