Technical characteristics

Resistance comparator R3015 (R 3015, R-3015)
Resistance comparator R3015 (hereinafter - comparator) is designed to determine relative difference resistance on a direct current (hereinafter - the relative difference z) of two discrete external and (or) integrated resistors, with no galvanic connection between themselves and the representation of the comparison result in percentage on the digital screen.
Comparison range 10-2Оhm-10⁷Оhm
Acceptable basic accuracy 0,1-0,0001%
Operating conditions:
Ambient temperature 10 to 35 °С;
Relative humidity 80% at 25 °C;
Voltage supply (220 ± 22)V;
Normal frequency (50 ± 1) Hz and (60 ± 1,2) Hz;
Distortion coefficient of voltage curve is not more than 5%;
External electric and magnetic fields, except the Earth field, not available;
Resistance comparator R3015, delivered to areas with tropical climate (comparators marked "P3015-4.1 **") should be placed in places with air-conditioned or partly air-conditioned.
 
Technical characteristic:
 
 The ranges of comparison, the value of voltage at the reference resistor Rn (URN) when comparing resistors correspond to those indicated in the Table 1. The comparator provides automatic and manual startup modes, and remote control mode (input-output data through the built-in interface) designed in compliance with the requirements of GOST 26.003-80.
The comparator provides automatic selection of the polarity and extent of the relative difference z: ± 0,01; 0,1; 1, 10, 100%. The comparator consists of two blocks: comparator (CB) and digital block (DB), connected together by two cables.
The digital display DB shows:
value of the measured relative difference z with the floating point, whose position corresponds to the limit of the relative difference according to the Table 2;
sign of the polarity of the measured relative difference z;
the letter "P" on the display digits, signals about overload in break of compared resistors circuit or a relative difference of z for more than 119.99%.
The duration of the measurement cycle for all types of starts is set automatically depending on the range of comparison in accordance with Table 3. Acceptable basic error limit of comparator for comparing resistors in all operating starts modes corresponds to the Table 1. The measured relative difference between the measured resistor z is equal to a percentage: Z = 100 ·(Rx - RN)/RN, where Rx and RN - real values ​​of resistances, of the measured and model resistors.
    Acceptable limit of comparators additional error, caused by the change in ambient temperature from normal (20 ± 2) ° C up to any in the range from 10 to 35 ° C, equal to half of the maximum permissible basic error for every 10 ° C of temperature change. Acceptable limit of additional error, caused by the change of supply voltage of ± 10% with nominal (220V), is equal to half of the maximum permissible basic error.
 The comparator has a device for introduction of the amendments to the real resistance value of resistor RN model from 0 to ± 0,0099% from its nominal value in steps of 0.0001%. The amendment should be introduced in the measurement of the relative difference of ± (0,000000 - 0,9999%).
Operating time setup mode (after switching on the network) - 30 minutes. Duration of continuous operation of the comparator without calibration and zeroing is at least 1 hour. Duration of continuous operation of the comparator is not less than 8 hours, not including time of the operating mode establishment. The time interval before re-enable is at least 30 minutes.
The resistance between any accessible metal piece and the body of any of the blocks and clamp "╧" does not exceed 0.5 ohm. Each block CB and DB has the insulation between supply chain, "220V" and a clip "╧", and between the supply chain, "220V" both blocks (blocks of CB and DB are connected with connecting cables) and the measuring circuit (short-circuited cable ends Rx and RN) in the normal conditions of use maintains during the action of 1min a test AC voltage with frequency (50 ± 1) Hz, which is in almost sinusoidal shape, with the value 1.5 kV.
The insulation resistance between the supply chain, "220V" in each block of CB and DB, and clamps "╧", and also between the supply chain, "220V" both of blocks (blocks of CB and DB are connected by connecting cables) and the measuring circuit (short-circuited cable ends Rx and RN) - at least 108 Ohm at a voltage of 100-200V in normal conditions of use. The power consumed by the comparator, not more than 110 V • A. Dimensions, mm, not more than CB: 450x25x450mm, DB 450x250x450mm. Weight of the comparator is not more than 30 kg.

We also provide such metrological procedure: calibration, tare, graduated, testing of measuring instruments.

The online store takes an active part in such procedures as electronic bidding, tender, auction.

If there is no site in the descriptive information you need on the device you can always turn to us for help. Our qualified managers will update for you on the technical characteristics of the device from its technical documentation: user manual, certificate, form, operating instructions, diagram. If necessary, we will take a photo of your device, or a device stand. You can leave feedback on the unit purchased from us, the meter, the device, indicator, or product. Your review for your approval will be published on the site without contact information.

 

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.
