Test-4 is a reliable support for calibration sessions, laboratory tests and of analog measurements simulation controlled by industrial devices (controllers, DAQ systems etc.). With a total accuracy better than 0.1%, and a whole resolution of 1 μA / 1 mV, Test-4 achieve accurate calibration results. It allows the simulation of ramps in both tension and current value (active or passive). Test-4 is supplied by 220 Vac power network with external AC/DC adapter or by 2 NiMH batteries providing approximately 20 hours of run time.
