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-overmoulded 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
MEGIT320 is also supplied with a switched test probe to speed hands free
testing.
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 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. |
