To measure DC current with a clamp-type ammeter, follow these steps
A clamp ammeter is a combination of a current transformer and an ammeter. The iron core of the current transformer can be opened when the wrench is tightened; The wire through which the measured current passes can pass through the open gap of the iron core without cutting, and the iron core will close when the wrench is released. The tested circuit wire passing through the iron core becomes the primary coil of the current transformer, and current is induced in the secondary coil through the current. So that the ammeter connected to the secondary coil can indicate the current of the tested circuit. The clamp gauge can be changed to different ranges by shifting the switch. But it is not allowed to operate with electricity when shifting gears.
Clamp gauges generally have low accuracy, typically ranging from 2.5 to 5 levels. For ease of use, there are also conversion switches with different ranges inside the meter for measuring different levels of current and voltage.
