Analog/Digital Hand-Held Megger Insulation Tester; 250 & 500V.
Analog/Digital Hand-Held Megger Insulation Tester; 250 & 500V.
The MIT220 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 series of instruments
offers 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 ABS, designed to withstand the rigours of hard use, and is small enough to drop
into your pocket when not in use.
Battery requirements are 6 AA batteries of either standard
alkaline or nickel metal hydride (NiMH) rechargeable type. A
low battery warning indicator gives advanced warning 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 Ω on continuity, of
which 0-10 Ω is performed at greater than 200 mA to meet
international electrical testing requirements.
Lead null is possible up to 9.99 Ω of test lead resistance,
ensuring the ability to null fused test leads as well as |
standard leads.
Continuity buzzer
A continuity 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 Ω threshold.
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 MΩ on 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.
The MIT200 series will find applications in electrical
contracting, both on domestic and industrial systems, as
well as site maintenance and service departments.
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 carry 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).
Every Megger instrument is designed with safety as its primary objective. All instruments meet or exceed the requirements of safety directive IEC 61010 and EN61557 for insulation and continuity testing.
A built-in voltmeter automatically switches in when the instrument is connected to a circuit with an AC or DC voltage greater than 25 V
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 injury or damage.
The MIT200 series has been designed for use on applications up to 600 V CATIII.
