Resistance Box R40104 designedfor use as multi-valuedelectrical resistancemeasurein DC circuits. Resistance Box operating conditionsaccording totable1. Climatic modification type YXL4.1according to GOST 15150-69.
Resistance Box R40104 basic parameters andOKP codesare shown in Table 2. Maximum power dissipation values on level are equalto nominalshown in Table 2. Acceptable deviation limit of Resistance box R40104 actual value from nominal in percentage,does not exceedaccuracy class values under normal using conditions: ambient temperature(20 ±1) °C;relative humidityfrom 25 to80%; atmosphere pressure 84-106.7kPa(630-800mmHg); AC; voltage orpower are notover nominal (table 2).
Resistance Boxes R40104 acceptable additional errorlimitcaused by changesin ambient air temperaturebetween the higher (lower)temperaturerange in normalusing conditions andpoint in adjacent temperature operating conditions range correspondingto the largestchange inRmax,is equal to0.05%.
Resistance Box R40104 belongs to group2,type1 according to GOST27.003-83, restored, repaired, single-functional.
