Bridge direct current R333 (R-333, R 333)

Desined for:
a) measuring the resistance of the bridge single scheme;
b) Cable Fault Locator with a hinge Varley;
c) the fault location cable loops through the Murray;
d) measuring the asymmetry of the wires;
d) the use of the bridge as a resistance box.
Range: 1 to 99990 ohms, from 1.10 to 0.9999 ohm -1, from 5.10 -3 to 0.0999 ohms, from 10 May to 999,900 ohms.
Accuracy class: 0.5, 1.0, 5.0.
Bridge direct current R333 are designed for:
a) measuring the resistance of the bridge single scheme;
b) Cable Fault Locator with a hinge Varley;
c) the fault location cable loops through the Murray;
d) measuring the asymmetry of the wires;
d) the use of the bridge as a resistance box.
Bridge direct current R333 is designed for operation at an ambient temperature of 10 ° to 35 ° C and relative humidity up to 80%. The normal operating temperature of 20 ± 5 ° C during operation of the bridge in the class 0.5, from 10 to 35 ° C during operation of the bridge in the class 1.0, 5.0.
Bridge direct current R333, available for export to countries with tropical climates (factory designation P333 T4.2), designed for use in dry heated rooms at an ambient temperature of 10 to 35 ° C.

Resistance to high level comparison of the bridge arm of the decade 1000 ohms. Resistance shoulders relationship for at least the 1st. Initial resistance store reference leg, ie resistance during the installation of all the decades of the switches on the zero reading is less than 0.02 ohms. The variation of initial resistance store reference leg caused by the change of the contact resistances and contact switching devices does not exceed 0,003 ohms.
Changing the error of indication of the bridge R333 caused by changes in ambient temperature rating noted above oh no more than every 5 ° C change in temperature than half the allowable value of the basic error.
The insulation resistance between all the electrical circuits of the bridge R333 and its case at a temperature and humidity specified above 200 MW. Insulation between insulated from the housing electrical circuits bridge R333 and his body can withstand for 1 minute 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 no more than R333 300x230x150 mm. Weight no more than 5kg.
