Technical characteristics
Measure of electrical resistance R3026
Also this device can be called: R 3026, R-3026, R30-26, R30 26, P3026, P 3026, P-3026.
R3026 measure of the electrical resistance multi-valued intended for use as a control measure resistance in DC circuits.
Measures R3026 presented modifications R3026-1 and R3026 -2.
Specifications R3026:

Limit of acceptable deviation of the actual value of the resistance measure, expressed as a percentage of nominal - less than ±(0,01+1,5·10-6·(111111,1/R-1)), where R - the nominal value of a resistor.
Instability R3026 per year:
- for R3026-1 - not more than ±(0,002+1,5·10-6·(111111,1/R-1))%;
- for R3026-2 - not more than ±(0,005+1,5·10-6·(111111,1/R-1))%.
Maximum permissible additional error, expressed as a percentage of the nominal value of a resistor, a change of the nominal power dissipation to any value that does not exceed the maximum power under normal conditions of use and the establishment of thermal equilibrium state is the value of instability for the year.
Maximum permissible additional error caused by changes in ambient temperature between the upper (lower) limit the range of normal conditions of use and the upper (lower) value of the operating temperature applications, numerically equal to the value of instability for the year.
Dimensions - 485×250×240 mm.
Weight R3026 - not more than 11 kg.
Operating conditions R3026:
Normal:
- ambient temperature - (20±0,5)° C;
- relative humidity - 60±20%.
Workers:
- ambient temperature for R3026-1 - (20±2)° C;
- ambient temperature for R3026-2 - (20±5)° C;
- relative humidity in the working temperature range of - 25% to 80%.

Description of the instruments taken from the technical documentation or technical literature. Most pictures of products made directly by our experts prior to shipment of goods. In the description of the device provided the main technical characteristics of the instrument: nominal measuring range, accuracy class, scale, supply voltage, size (size), weight. If the site you see the discrepancy device name (model) specifications, photo or documents attached - let us know - you will get a useful gift with-selling device.
While the need to clarify the overall weight and size or the size of the individual meter you can in our service center. If you need our engineers will help you choose the most complete analog or a suitable replacement for the device you are interested. All counterparts and replacement will be tested in one of our laboratories with the full compliance to your requirements.
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.
We 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.
