Accuracy class 0.01
Electrical resistance standard P331
P331 electrical resistance coils are a standard measure of resistance and are designed for testing and adjusting working resistance coils in direct current circuits, as well as standard and working (laboratory) measuring instruments.
The P331 electrical resistance coil is operated in a liquid medium (capacitor oil, kerosene, organosilicon liquid).
The permissible deviation of the resistance of P331 coils from their nominal values due to inaccuracy of adjustment at a temperature of 20°C and power not exceeding the nominal value is no more than ±0.01%.
The change in resistance over the course of a year is no more than ±0.002% for P331 coils.
The change in the actual resistance value when the power changes from the nominal to the maximum permissible value at a steady thermal state for P331 coils is no more than ±0.005%. 
Overall dimensions: 110x170 mm. 
Coil weight without oil: no more than 1 kg.
Mean time between failures for P331 coils is 200,000 hours. Operating conditions for P331: ambient air temperature 15...30°C; relative humidity 80% (at 20°C).
