Willow City, the lowest supply DD862 single phase mechanical meter old home

For more information on single-phase mechanical meter: DD862-4 single-phase power meter is widely used in domestic AC induction energy meter, the product is the joint design of products, after nearly 20 years of production use, and technical improvements, make the product more stable and reliable performance, the products in the domestic first international authority through the Netherlands KEMA test, used to measure single-phase active energy. It provides a bi-directional measurement, pulse output, communications, and other features of the product carrier according to user needs. 1.1 single-phase energy meter main purpose and scope DD862 single-phase energy meter induction meter, used to measure the reference frequency 50Hz single-phase AC active energy of its technical indicators in line with GB / T15283-1994 requirements. 1.2 single-phase energy meter meter environmental conditions fixed installation in indoor use, suitable for an ambient temperature of -10 ~ + 50 ℃, relative humidity less than 85%, and ambient air should not corrosive gases, to avoid dust, salt spray, condensation and other effects. 2. Single-phase energy meter installation and use of the single-phase energy meter 2.1 meter in the factory have passed the test and add seals, seal integrity should be checked before use before installation. Lead Free seal or too long storage period meter, it must be approved by authorized agencies to re-examine, before installation. 2.2 Single-phase energy meter with three screws, according to the illustrated installation size 140X105 mm pre-drilled holes, and ensure power meter After a fixed vertical position and outperform difference does not exceed 1 degree 2.3 single-phase energy meter must strictly follow the button cover plate terminal, access Terminal Block Use the drop coins, coins, cross-sectional area should ensure carrying capacity per square millimeter is not greater than 5A, fixed sure to tighten the screws, to avoid bad contact or a lead is not fine heat and burning. 2.4 single-phase power meter copy should be noted counters and reading, red box in the figure decimal, black square in the figure is an integer, such as no red box is the whole integer. Example 5 (20) A, a red box number 00,885 That last meter reading 88.5kwh, after the second meter number 01248 That 124.8kwh, ie actual consumption of 36.3kwh. 3. Single-phase energy meter guarantee period from the date of sale of the company, when the user fully comply meter transport, storage, installation and use regulations, and in the Company's lead Under conditions of complete closure, power meter does not meet the requirements of GB / T15283-1994, the company's commitment to give return within three months of substandard products, giving one year limited warranty, given the warranty to three years. 4.
