The compact MIT200 testers incorporate a number of safety features, including live circuit protection giving an audible warning even if the instrument's internal fuse has failed. The testers incorporate backlit LCDs with a large analogue-style arc to provide a rapid indication of results, together with a digital readout to give accurate numerical data for inclusion in reports and test certificates. After a test, results are displayed until the next test is initiated. Instruments in theMIT200 range are available in two versions. The MIT220 offers insulation testing at 250V and 500V, while the MIT230 allows testing at 250V,500V and 1000V. MIT200 instruments are supplied complete with test certificates and test leads. The leads feature right-angled connectors to prevent tangling and reduce stress in the cable. MIT230 testers and accessories are supplied in a rigid carrying case.
