How do you measure current with a caliper meter?
Measurement methods: firstly, the jaw clamp ammeters clean (to ensure full, jaw anastomosis) and then estimate the current measured wire, the clamp ammeters stalls to proper position (if you do not know the measured current, the current position is adjusted in sequence from large to small, every adjustment must be table from the measured wire), then measured a wire into the ring opening on ammeter, current at the table shows that the measured conductor, in measure second and third respectively. At the same time as the two into the ring clamp meter, ammeter display is the current third wire. The three are placed in the table at the same value as zero (according to Gil Hof's law, flowing in or out).
First of all, the gear to AC or dc gear, select the larger value, current gear, so as not to burn out, and then put a single line of power into the jaws, as far as possible in the middle position,
The iron core of the current transformer can be opened when the wrench is tightened; the wire through which the current is measured can be cut through the opening of the iron core without cutting off, and when the wrench is released, the iron core is closed. Through the test circuit of the core, the wire becomes the primary coil of the current transformer, in which the current is induced in the two coil through the current. A current meter connected with the two coil is then instructed to measure the current of the line being measured.
Clamp meter (clamp meter), is a set of current transformer and current meter in one meter, is an important branch of digital multimeter, the measured current and current transformer and its working principle is the same. Clamp meter is composed of a current transformer and current meter assembly.
Select the appropriate gear (automatic range is not selected), open the jaw will be measured wire, as for the jaw, the closure jaw can read.
