Bridge direct current R333 designed for operation at an ambient temperature of from 10°to 35 ° C and relative humidity up to 80%. The normal operating temperature of 20±5°C during operation of the bridge in class 0.5; from 10 to 35°C during operation of the bridge in class 1.0, 5.0.
Technical data
Resistance to high level arm of the decade comparison of the bridge is 1000 Ohms. The resistance of the shoulders of the relations of not less than 1ω. Initial resistance store reference leg, ie resistance during the installation of all the decades of the switches on zero readings does not exceed 0.02 Ohm. The variation of initial resistance store reference leg caused by the changing resistances and contact switching devices does not exceed 0,003 Ohms.
Change error of indication of the bridge R333 caused by changes in ambient temperature, does not exceed the specified above for every 5°C change in temperature half the allowable value of the basic error.
The insulation resistance between all electrical circuits of the bridge R333 and its case in a temperature and humidity specified above 200 MW. Insulation between insulated from the housing electrical circuits of the bridge R333 and his body can withstand for 1 minute action of the test voltage of 500 V is practically sinusoidal frequency of 50 Hz.
Lever switches of the bridge R333 withstand 50,000 strokes without any defects. Overall dimensions of the bridge R333 no more 300x230x150 mm. Weight not more than 5kg.
