The ETK series proposed by Mitec is the evolution of the automatic testing bench for electrical safety measurements model ATE04E. This line of instruments is positioned between computerized stations with integrated power section, on one hand, and programmable microcontroller stations, instruments only, on the other hand (without integrated power section). Its peculiarity consists in the sober combination of a high-precision instrument, user-friendly fast and reliable but low-cost, with a power section, integrated into the same cabinet, which allows executing functional tests with stabilized power supply and automatic management, in execution phase, of the voltage setup defined in the product testing programme chosen among those stored in the tool memory.
