Safety
has been an important design feature of the MIT200. Should one of
the instruments be inadvertently connected to a live circuit, a
warning is immediately sounded, even if the instrument’s internal
fuse has failed. The voltage is then displayed and testing is inhibited.
Automatic warning of fuse failure is also provided, saving time-consuming
manual fuse checking.
The instruments
are easy to use. Backlit LCDs include a large analogue-style arc
that provides a rapid indication of results, together with a digital
readout to present precise data for inclusion in test reports and
certificates. After a test, results are displayed until the next
test is initiated, eliminating the need for a hold button. Knobs
and buttons are also colour coded for convenience.
Instruments
in the new range are currently available in two versions. The MIT220
offers insulation testing at 250V and 500V, while the MIT230 allows
testing at 250V, 500V and 1000V. Both models feature 1000megohm
insulation testing at all supported voltages, 200mA continuity test
current and a fast continuity buzzer with a 5ohm threshold. Continuity
tests are fully automatic, freeing both hands and removing the need
to press the TEST button, but still features live circuit detection.
MIT200 testers
are supplied with test leads that feature right-angled connectors
to prevent tangling and reduce stress in the cable. MIT230 testers
and accessories are supplied in a rigid carry case. They are also
supplied with free calibration certificates.
