atmospheric pressure 86-106 kPa (650-800 mm Hg. cent.).
Shop refers to recoverable products.
The permissible deviation of the actual resistance value of the nominal store R4002 (percentage) does not exceed the accuracy (described above) under the following standard conditions: ambient temperature (20 ± 1) ° C (293 ± 1) K, relative humidity (60 ± 20)%, atmospheric pressure (100 ± 4) kPa (750 ± 30) mm Hg. Art. , Constant current, power dissipation or above the nominal voltage (op. above) aisle of additional error R4002 store, change the temperature of the surrounding air between the upper (lower) limit the range of normal conditions of use and by some point in the related field of temperature operating conditions of use corresponding to the maximum change in resistance should be equal to ± 0,05%.
Mean time between failures shop R4002 in the working conditions of application of at least 10,750 hours
The average service life of at least 8 years.
The probability of failure for no metrology calibration interval of 3 years, no less than 0.9.
