Ammeters E378 and voltmeters E378 allow basic measurement error does not exceed ± 1,5% of full scale value. For devices with overload scale of congestion basic error does not exceed ± 6% difference between the final values of the loading scale and range measurements.
Ammeters E378 and voltmeters E378 under the influence of various factors admit the errors in the measurements:
Changing E378 readings due to abnormal ambient temperature of 20 ° C (in the range of -40 º C to +50 ° C) does not exceed ± 0,8% - for Class 1.5 for every 10 degrees.
Ammeter E378 and voltmeter E378 suitable for use at temperatures from -50 º C to +60 º C. Relative humidity should be no more than 95% (at +35 º C).
Ammeters E378 and voltmeters E378 designed for flush mounting on vertical or horizontal panels (panels) made as of the magnetic and non-magnetic materials.
When installing the E378 need to adhere to the following rules:

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.
