Insulation testing has been enhanced with feedback controlled test voltages to limit over-voltage to 2%, rather than the industry standard 10-20%.
Continuity testing is now significantly faster, and a single autoranging 0.01 Ω to 1.0 MΩ function replaces the “ohms” and “kOhms” ranges. Retained are the 200 mA and 20 mA test options.
Replacing the original MIT400 instruments the new units feature a redesigned case, back-stand, and 6 cell battery compartment with separate fuse access.
All instruments are over-moulded for increased protection and achieve an IP54 weatherproof rating.
The MIT415/2 and MIT417/2 include additional low voltage insulation test voltages at 10 V and 25 V for ESD and low- voltage signal-wire testing as found in elevators. The MIT415/2 also incluses a display option to show 105, 106, 107 instead of the usual KΩ, MΩ, GΩ etc.
