δ=±(0,5+n(Ak/Ax)) - To within 10 mA and 10MOm,
    where: - δ - basic accuracy,%;
    - N - number one - 0,1, 2, 1c corresponding measurement time, and with 0.1 to 0.01;
    - - The measured current or resistance;
    - - Set a limit of measurement.

    The device B7-18 with admissible repents basic frequency measurement error, calculated by the formula:
δ=(δc+(1/ƭx×T)),
    where - δ - basic accuracy,%;
    - Δ with - relative error defined by varying the frequency of the internal reference oscillator frequency or frequencies introduced exemplary action;
    - ƭx - The measured frequency;
    - T - time measurements.

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.
