Resistance of the highest decade back comparison bridge 1000 Ohm. Resistance of ratio back is at least 1Ohm. Primary resistance boxcomparative back, resistance during installation all decades switches on zero is less than 0.02 Ohm. Variation of primary resistance box comparative back caused by changes in contact resistances and contact switching devices does not exceed 0.003 Ohm.
Error changes in bridge P333measurements, caused by changes in ambient temperature does not exceed a half allowable values of basic error for every 5 °C of temperature changes.
Insulation resistance between all bridges P333 current conducting circuits and its case at temperature and humidity is 200 MOhm. Insulation between isolated from bridge P333 case conducting circuits can withstand for 1 min test voltage of 500 V in practically sinusoidal 50 Hz frequency.
