Decade resistor

SRM-1 is designated for imitation and value setting of active resistance of impedance in a short circuit loopwith 230/400 V voltage, 50/60 Hz AC. The required resistance is set by the user by means of decade switches of resistance boxes. SRM-1 is applied as reference standard equipment for verification and calibration of testers of electrical safety parameters of electric plants in the metrological laboratories. The resistance box characteristics enable to use it also for calibration of the widely spread meters of electrical resistance to direct current.
