The MIT200 is one of the smallest insulation testers available on the market today. With options of a two voltage tester to a three voltage instrument, the MIT200 instruments 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 include the benefits of an LCD display, such as robust, clear and accurate measurement, with an analogue pointer response for evaluating circuit charge and discharge characteristics.

The instrument housing is a tough ABS designed to withstand the rigors of hard use, whilst 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. 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 with 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 5 Ω threshold.

Insulation testing

The instruments offer one of 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 from 250 V upwards.

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.

Developed, after extensive customer research, specifically to meet the needs of today's electrical contractors, the new MIT300 range of insulation and continuity testers from Megger is not only durable and easy to use, but also incorporates a comprehensive set of features designed to ensure operator safety, even under conditions of accidental misuse.

The range includes four models, ensuring an exact match for the needs of every user, all of which offer automatic discharge of the circuit after testing, audible and visual warning if the test probes are applied to a live circuit, and a test inhibit feature which operates automatically under live circuit conditions. The units also conform fully to IEC 61010-1 for use in Category III 600V applications, and provide all of the facilities needed to meet insulation testing requirements relating to the current edition of the IEE Wiring Regulations.

In line with other products in Megger's comprehensive new contractor range, MIT300 insulation testers feature rugged construction, with an impact-resistant rubber-overmolded case, and innovative circuitry which guarantees high accuracy combined with stability of calibration.

All instruments in the new range provide indication of insulation resistance up to 999Mohms, 200mA continuity testing, a fast-reacting continuity buzzer, and facilities for nulling the resistance of the test leads. The entry-level MIT300 offers insulation test voltages of 250V and 500V, while the remaining models allow testing at 250V, 500V and 1,000V.

In addition to the basic features, the mid-range MIT310 adds a default voltmeter function, while the MIT320 supplements these facilities with an a backlit display, illuminated range panel, insulation limit alarm, resistance measurement, and an adjustable threshold for the continuity buzzer. The MIT320 is also supplied with a switched test probe to speed hands free testing.

The model MIT330 has the ability to store and download test data for up to 99 jobs. Download software is included. An illuminated switched test probe is available as an optional extra for use with the MIT320. The MIT310, and MIT320 testers incorporate dual solid-state displays which simultaneously show the test results numerically, and in the form of a moving-arc bar graph that accurately simulates the operation of an analogue meter.

All testers come complete with a full NIST traceable calibration certificate. For users who prefer a true analogue device, however, Megger is offering the MIT310A which has features similar to those of the MIT310, but with a conventional moving-coil meter movement in place of the digital display.

The new Megger MIT400, MIT410, MIT420, MIT430, MIT480, MIT481, MIT485, and MIT40X industrial insulation and continuity testers combine the latest range of measurement techniques with new instrument design to provide a state-of-the-art tester that is compact and comfortable to hold. The MIT400 series directly replaces the well established BM400 and BM80, given greater functionality with simplified operation, greater application range and increased safety.

Every tester is designed to meet the stringent international requirements of IEC1010-2 as well as those for EN61557,and sealed to IP54, providing a weatherproof case to reduce the chances of water ingress, including the battery and fuse compartment.

Rubber over molding combines the tough shock absorbing outer protection with excellent grip, on a strong modified ABS housing, providing an almost indestructible case.

Operation
Operation of all instruments is kept simple. All functions are displayed on the range selector, with additional push-buttons under the display.

The display has a major and minor 3 1/2 digit readout, plus an analogue arc. All primary results are displayed in the larger digits. Additionally, auxiliary test information such as frequency, leakage current, insulation or circuit voltage etc is displayed in the smaller secondary 3 1/2 digit display within the main window.

Insulation Testing
The insulation test voltages available range from 50 V to 1000 V depending on model, with a special 10V to 100 V tester for awkward low test voltages. Insulation resistance measurement extends from 20 G½ to 200 G½,with the option to display the insulation test voltage or leakage current on the secondary display.

Timed insulation testing of 30/60 seconds and 1min/10min for DAR/PI testing is also available on the MIT400, MIT410, MIT420, MIT430, MIT40X, but excludes the MIT480. A general timed measurement is also available with selectable 1 minute steps up to 10 minutes.

A buzzer threshold permits an operator to set a minimum buzzer limit. If the insulation resistance exceeds the mini-mum limit the buzzer sounds without the operator having to check the actual measured value.
