• measurement voltage selected within the range of 50…500 V with steps of 50 V and from 500 to 5000 V with steps of 100 V • continuous reading of measured insulation resistance or leakage current • automatic discharge of the measured object’s capacitance upon completion of insulation resistance measurement • sound signalling of five-second time intervals, facilitating capture of time characteristics • timing of measurement time T1, T2 and T3 for measurement of dielectric absorption ratio (DAR) and polarization index (PI) • reading of actual measurement voltage during measurement • protection against measurement of live objects • two- or three-lead method of insulation resistance measurement • insulation resistance measurement according to the RampTest method and breakdown voltage measurement with ramping rate up to ~1 kV/s • measurement of direct and alternating voltages within the range of 0...750 V • 990-cell memory (11,880 entries), data transmission to PC via USB cable • power supplied by accumulator • instruments meet the requirements laid down by standard EN 61557 • the meter can be powered and charged from an external power adapter or from a car lighter socket The Sonel MIC-5001 functional insulation resistance meter is a handy tool for measuring insulation resistance up to 5 TΩ. It is used in a wide range of applications, including industry, railway industry, and housebuilding industry. The device combines many advantages - it has an ergonomic shape and a robust casing with a high level of protection; low battery power consumption; and it is possible to recharge the batteries even during measurements.
