Store R4042M measuring resistance designed for use as a multi-valued measure of electrical resistance (MMES) in DC.
Ambient air temperature of 10 to 40 ° C
relative humidity from 25 to 80% in the working temperature range;
pressure 86-106 kPa (650-800 mm Hg).
- UHL, category 4.2. GOST 15150 - 69.
Store R4042M are recoverable single-channel, monofunctional products.
Main parameters and codes OKP stores are listed in Table. 1.
The permissible deviation of the actual value of the resistance of the rated stores R4042M not exceed ± 0,1% under the following standard conditions:
ambient temperature (20 ± 1) ° C;
relative humidity (60 ± 20)%;
atmospheric pressure (100 ± 4) kPa (750 ± 30) mm Hg;
current is constant;
voltage - not the rated (Table 1).
The limit of additional error shops R4042M caused by changes in ambient temperature between the upper (lower) limit the range of normal conditions of use and by some point in the related field of application temperature operating conditions corresponding to the largest change of resistance is ± 0,1%.
Mean time between failures stores R4042M in normal conditions of use not less than 6000 hours average lifetime of at least 10 years of age.
