The мультиметр detects the розімкнутий ланцюг несправність of the освітлення ланцюг
1. Несправність явище і причина
2. Overhaul of open circuit faults
(1) All open circuits.
This type of fault mainly happens on the main line, in the power distribution and metering devices, and within the scope of the household devices. Usually, the connection of each joint of the the above-mented parts (include the melt terminal) should be checked in turn. Generally, the failure of the wire head to break away from the connection is the most common; secondly, check the opening and closing of the the динамічний і статичний контакти of each line switch .
(2) Partial open circuit.
This type of fault mainly happens within the range of branch lines. generally, check the connection of each wire head first, and then check the shunt switch. If the cross-section of the shunt wire is small, it should be considered that the core wire may be broken in the in the insulating layer and cause a local open circuit.
