Also, fast detection circuitry prevents damage to the
instruments if accidentally connected to live circuits or across
phases.

Extensive results storage capability – store test date for
later recall (Models MIT420, 430, 481 and 485)
Bluetooth download capability – wireless transfer of stored
results to a PC (Models MIT430 and 485)
Stylish tapered design and center button placement – easy
to use with either hand

Any live circuit detection inhibits any insulation testing on
circuits above 50 V (75 volts on Telecom models)
Any live circuit detection and test inhibit on continuity
measurements
Default display of live circuit voltage on all ranges
Detection and inhibit features function even if the
protections fuse has failed
Set of silicone test leads – Flexible and long lasting,
these leads prevent errors from test lead leakage on high
resistance type of insulation testing. They also provide
increased accuracy above 10 GΩ.
Rugged instrument rubber boot with built-in stand–
Protects the instrument from dings and drops and provides
an easier, better grip of the instrument.
Plug-in switch probe – Allows the user to remotely
perform insulation tests, reducing the time taken to
perform a test. Not included with the MIT400 and 40X.
High-impact polypropylene carry case – Further protects
the instrument and provides space for the leads, switch
probe, etc.
Free calibration certificate (not included with the MIT40X).
Owner information CD.
Three year product warranty.
