Technical characteristics

Inductance standard  R593 (R-593, R 593, p 593, p-593, p593)
Designed for use as an AC element in measuring systems with frequency of 1 kHz to 10000kHz.
Standard’s nominal value of inductance 0.01 mkH- 100mH
Accuracy class: 1; 2; 5
Valued Inductance standard  R593 (hereinafter - standard) are designed for use as an AC element in measuring systems with frequency of 1 kHz to 10000kHz.
Inductance standard  R593 designed for use in moderate climate conditions in dry heated rooms at ambient temperature of 10 to 35 ° C and relative humidity up to 80% at 25 ° C.
 
Technical characteristics

     Inductance standard  R593 correspond to GOST 21175-75. Inductance standard nominal value (L), accuracy classes (K), normal frequency (f), attestation fixed-frequencies, maximum current values (I), maximum operating voltage values (U), lowest values quality factor (Q) for frequencies f shown in Table 1. Acceptable basic error limit, shown in percentage of standard’s inductance nominal value is equal to accuracy class at following normal conditions:
ambient temperature (20 ± 5) ° C;
relative humidity (65 ± 15)%;
normal frequency;
current value is not more than maximum with curve sinusoidal form and distortion coefficient do not exceed 5%;
no external electric and magnetic fields, except Earth field.
Standard accuracy attestation at inductance with above requirements is shown in Table 2, under condition when frequency deviation is not more than ± 0.5%.
Determination quality factor Error (δ) in percentage or AC resistance (Δ) in Ohm considering normal conditions (above) does not exceed:
δ = ± (0.005 Q + 2) (1)
Δ = ± (0.02 R + 0.001), (2)
where Q – standard measured quality factor
R - standard measured resistance AC, Ohm.
Standard R593 quality factor is calculated by the formula:
Q = (2π • f • L) / R, (3)
where f - measurement frequency in Hz;
L - the measured inductance value, H. 
Inductance standard  R593 additional accuracy error caused by ambient temperature deviation from specified in normal conditions to any temperature in working temperature range, does not exceed every 10 ° C of temperature changes than half of maximum permissible basic error.
          Inductance standard  R593 AC or quality factor resistance changes, caused by ambient temperature deviation from specified in normal conditions to any temperature in working temperature range, does not exceed every 10 ° C of temperature changes, expressed by dependencies: ± (0.06 R + 0.001) Ohm; ± 0.06 Q.
Standard’s P593own capacity with nominal inductance values is over 1mkH and do not exceed 15pF. Dimensions, mm, do not exceed:
diameter 100, height 150 - for L ≥ 1mkH;
diameter 40, height 160 - for L ≤ 0.3 mkH;
490 x 335 x 185 - suitcase for packing.
Each standard weight does not exceed 0.7 kg.
Standard P593 set weight with suitcase does not exceed 15 kg.

In the technical documentation for each device or product, information is provided on the list and amount of precious metals content. The documentation gives the exact weight in grams of precious metals: Au gold, palladium Pd, platinum Pt, silver Ag, tantalum Ta and other platinum group metals (PGM) per unit item. These precious metals are found in nature in very limited quantities and therefore have such a high price.

On our website you can familiarize yourself with the technical characteristics of devices and obtain information on the content of precious metals in devices and radio components manufactured in the USSR. We draw your attention to the fact that often the actual content of precious metals differs by 10-25% from the reference one in a smaller direction! The price of precious metals will depend on their value and mass in grams.

All text and graphic information on the site is informative. The color, shade, material, geometric dimensions, weight, content, delivery set and other parameters of the goods presented on the site may vary depending on the batch of production and year of manufacture. Check with the sales department for more information.

If you can make repairs to the device yourself, our engineers can provide you with a complete set of necessary technical documentation: circuit diagram TO, ER, FD, PS. We also have an extensive database of technical and metrological documents: technical specifications (TS), the terms of reference (TOR), GOST (DSTU), the industry standard (OST) test procedure, the method of certification, verification scheme for more than 3,500 types of measuring equipment from the manufacturer this equipment. From the site you can download all the necessary software (the software driver) is required for the product purchased.

Our company carries out repairs and maintenance of measuring equipment in more than 75 different factories of the former Soviet Union and CIS.

We also have a library of legal documents that are related to our field of activity: the law, code, ordinance, decree, temporary position.
