MIT300 Series
Insulation and Continuity Testers
DESCRIPTION
The Megger MIT300 series features:
Digital or Analogue: The Megger MIT300, MIT310 and
MIT320 all feature the popular Megger digital/analogue
display. Large 20mm high characters provide very clear
readout, combined with an analogue arc for the feel of an
analogue instrument, with a true analogue response.
The Megger MIT310A has a moving coil display for those
who prefer a real moving needle. Black decals on a white
background give high contrast, even in poor light
conditions.
Tough:-
n Designed to take the bashing that testers receive on site,
the Megger MIT insulation testers are rubber armoured.
n The rigid display cover folds right out of the way during
testing and locks down to protect the display when it is
finished.
Simple to use:-
n No buried functions mean it is obvious how to use the
Megger MIT.
n Colour coded ranges help test selection, reducing testing
time and help with fault location.
n A user guide in the lid provides all the basic information.
Hands free use:–
n It hangs comfortably around the neck for hands-free use
because the instrument is carefully balanced.
n Continuity and buzzer testing starts automatically on
connection to the circuit.
n Insulation tests being activated from the instrument or the
switch probe, supplied with MIT320 and MIT330 (not suit-
able for the use with the MIT300 or MIT310).
Backlighting:-
n Both the display and the range selected can be read in the
dark because the MIT 320/330 has a backlit display and
range selection.
Safety features:- To protect the user and the tester from
incorrect use the MIT series all have an extensive range of
features known as the Megger Intelligent Safety System
including:
n Safety Interlock – prevents unsafe connection of test leads
n Safe contact detectors – Even if the MIT is connected to
a live circuit whilst on continuity setting the tester will
remain safe and not be damaged.
n Live voltage warning – alerts the operator when a circuit
voltage over 25 V exists.
n Safety lockout – Prevents the test from operating when
the circuit voltage is >50 V.
n Continuity check – prevents a continuity test or buzzer
test on a live circuit.
The MIT300, 310, 320 and 330 meet or exceed the UK and
International Wiring Regulations, including requirements
of BS7671 and VDE 0413 parts 1 and 4, HD 384, IEC 364,
NFC15-100, NEN3140, ES59009 and EN 61557.
n Extremely easy to use
n Tough rubber armoured case
n Self contained protective cover
n Live circuit warning
n Weatherproof to IP54
n Intelligent Safety System for protection.
n Result storage and downloading
n Download software included
n USB interface
