Plastic security seals for use

1, inductive (clamp) (AC) Usage: Select a pliers on the clamp into. 2, the access type usage: access circuits and electrical equipment series. Note ammeter measuring the maximum limit, the detected current can not be greater than the maximum limit measurement meter. Power supply in a separate table is, two or more tables can share a power supply. Digital ammeter current ratio selection: current ratio choice is to be measured according to the scope of the current election, there is a change in the selection based on the main circuit current. For example, 100/5 ratio of the transformer is to become a 100A current 5A current input ammeter, digital ammeter display the actual measured values​​. Therefore, the current digital ammeter on the ratio selection requirements, the size of the transformer generally require 1.2 to 1.5 times the rated current of the main circuit. Scope: financial, power, department stores, shipping, instruments, boxes, postal, customs, railway, transportation, water, electricity, gas, military, chemical, oil transportation, bus, shipping companies, logistics companies, supermarkets, gas meter, domestic air transport, international air transport, ore, cement, foreign trade commodity inspection, product testing, transport handling equipment, drum packaging, petrochemical containers, energy metering, tight seal to prevent theft and other industries. 1, designed by party cards and production of electronic seals, the city's electricity supply certain industries. 2, and its products are cleverly designed, exquisite workmanship, literacy rate, large storage capacity and other characteristics. 3, a good solution to the electricity sector meter box security lock control problems due to seal electronic products, when cut "tail" at the same time, you can not form a signaling pathway, the data will not be read. 4, each a meter installed an electronic seal, can finish well protect national electricity is not lost.
