Electrical resistance coil R310 represents an exemplaryresistance standard and is designed for testing and fitting working resistance coils in DC circuits, as well as exemplary and working (laboratory) measuring devices.
Electrical resistance coil R310 operates in liquid environment (capacitor oil, kerosene, organosilicium fluid).
    Acceptable resistance deviation of coils P310 from their nominal values caused by  adjustment inaccuracy at temperature of  20 ° C and power not exceeding nominal:
     for accuracy class 0.01 is not more than ± 0.01%;
     for accuracy class 0.02 is not more than ± 0.02%.
 Resistance change during the year is not more than:
     for coils
R310 accuracy class 0.01 ± 0.002%;
     for coils
R310 accuracy class 0.02 ± 0.005%.
Real resistance value change at power change from nominal to maximum acceptable in steady thermal conditions:
     for coils
R310 with accuracy class 0.01 is not more than ± 0.005%;
     for coils R310 with accuracy class 0.02 is not more than  ± 0.02%.
Dimensions 110x170 mm.
     Coil weight without oil is not more than 1 kg.
     Mean time between failures: is at least 66000 hours for coils
R310. Operating conditions of  R310: ambient temperature 15 ... 30 ° C; relative humidity 80% (at 20 ° C).
