    Shop resistance R327 (R-327, P 327, p327, p 327, p-327)
    Designed for use in DC as a variable measure of electrical resistance.
    Accuracy class 0,01 / 1,5 x10-6. The shop has six decades of the 10 x (10,000 + 1,000 + 100 + 10 + 1 + 0.1) ohms. The nominal power level (with a resistance of from 1 to 104 ohms) - 0.1 Tues

    Shops resistance R327 are designed for use in DC as a variable measure of electrical resistance.
    Shop resistance R327 is designed for operation at an ambient temperature of 15 to 30 ° C and relative humidity up to 80%. The normal operating temperature of 20 ± 1 ° C.
    Stores R327 for export to countries with tropical climates (factory designation R327 T4.1) are intended for indoor air-conditioned at an ambient temperature of 15 to 30 ° C.
 
    Technical data

    Shop resistance R327 corresponds to the requirements of the manufacturer's specifications and GOST 7003-74. Accuracy class 0.01 / 1.5 10-6. The shop has six decades of the 10 x (10,000 + 1,000 + 100 + 10 + 1 + 0.1) ohms. The nominal power level (with a resistance of from 1 to 104 ohms) - 0.1 Tues Rated current shop when you turn of the decade 10 x 0.1 ohms is 0.3 A. The basic error of the store, determined at 20 ± 1 ° C, does not exceed the values ​​calculated by the formula:
      δ = ± [c + d (Rmax / R - 1)]%
    where c is a constant 0.01;
    Rmax - the greatest resistance to the store, Om;
    R - the nominal value of the included resistance, ohms;
    d - constant, equal to 1,5 • 10-6

    Additional error indications shop R327 to changes in temperature for every 5 ° C in the range 15-30 ° C does not exceed the permissible value of the basic error. Initial resistance to the store, that is, Resistance to install brushes all the switches on the decadal zero readings does not exceed 0.012 ohms. The variation of the initial resistance of less than 0.0012 ohms. Termokontaktnaya emf unloaded in the measurement chain store in the R327 set to zero readings brushes switch does not exceed 1mkV. The insulation resistance between the electrical circuit and the body shop for at least 1010Om at a voltage not exceeding 2kV test and not less than 300V.
    Toggle switches withstand the store 100 000 strokes without any defects. Overall dimensions of the store no more than R327 350 x 235 x 200 mm. Weight no more than 7.5 kg.
