The Sonel SRM-3-100/3 Standard Manual Resistor 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.
The resistance box of the SRM-3-100/3 is designated for provision of wide range of reproducible resistance values, it is distinguished by the gradation based on the amount of the involved decades (3) and correspondingly typical size of the case. At the same time, this model is represented by type 3 accuracy class (0.5 %, 0.5 %, 0.5 %). It is designated for application in direct and alternating current circuits.
