High Current Decade Resistor
The Sonel SRM-0R1-4k1 Standard Manual Resistor is designated for imitation and value setting of active resistance of impedance in a short circuit loop with 230/400 V voltage, 50/60 Hz AC. The required resistance is set by the user using decade switches of resistance boxes.
SRM-0R1-4k1 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.
