Technical characteristics
Vibration, impact resistant, splash-proof, for harsh environments.
Ammeter M1620 and voltmeter M1620 is a magneto-electric devices unipolar system design, made in cases of splash-proof and designed for flush mounting.
Structurally, the ammeter M1620 and voltmeter M1620 consist of the measuring equipment, casing, base and casing. Case made from a thermoplastic and has two compartments. In the front compartment of the housing M1620 placed the measuring mechanism in the rear compartment - elements of the electrical circuit. To the rear of the chassis is mounted plastic cap. The front of the device is closed trim or aluminum alloy, which is pre-installed sight glass. In the center of the glass is offset with a gasket that provides splash protection ammeters M1620 and voltmeters M1620.
Ammeters M1620 and voltmeters M1620 have a scale, made of thermoplastic plastic. Scale marks are applied on the outer edge of buoyant dial so that the needle end is aligned with them. This excluded when counting error of parallax. At the bottom of the scale devices M1620 applied indicate the measured values and data characterizing devices.
The construction provides a spring supports the movable portion cushioning devices M1620 shake and vibration in the axial and radial directions. Switch P1825 features a rectangular molded case splash-proof. Switch housing is equipped with four eyelets for fixing.

Ammeters M1620 and voltmeters M1620 have the following limits of additional error caused by:
Ammeters M1620 and voltmeters M1620 stand following the insulation test voltage (at ambient temperature of 20 ° C ± 5 ° C and a relative humidity of 80%):
The insulation resistance of electrical circuits M1620 devices relative to the body in an ambient temperature of 20 ° C ± 10 ° C and 80% relative humidity for at least 20MOm.
Ammeter M1620 and voltmeter M1620 should be stored in closed containers in heated rooms on the shelves ambient temperature of 5 ° C to 40 ° C and a relative humidity of 80% at a temperature of 25 ° C.
Ammeter M1620 and voltmeter M1620 can be transported in a package of GOST 9181 at an ambient temperature from -50 ° C to 70 ° C and relative humidity up to 100% at 50 ° C by all modes of transport, and aircraft - in an enclosed heated compartments.

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.
