Kaip matuoti įtampa su a spaustukas ampermetras
The clamp ammeter is actually an electromagnetic inductor. The energized wire generates a magnetic field. The magnitude of the current produces a different magnetic field strength. The current value converted on the clamp meter is different due to the difference in the three-phase voltage, so each phase The current hole on the battery is different, so you can only measure the current of a single phase, and then calculate the average current. Finally, whether it is a three-phase 380v voltage or a two-phase 220v voltage, the method used is the same.
The clamp ring of the clamp multimeter is set for measurement current, but since the clamp multimeter is called, it does not only measure AC current.
Many clamp meters have the functions of measurement resistance, AC and DC voltage, etc. Simply put, the functions of ordinary multimeters can be implemented on clamp multimeters. Many clamp meters have the function of measurement DC current, but most of them currently use test leads instead of clamp rings.
Adjust to the current gear, and directly clamp the wire to be measured with portper.
Kai kurie spaustukas metrai gali matuoti įtampa, o kiti negali. Tie kad gali matuoti įtampa yra įrengta su testu laidais. Įterpti the test leads into the cortent holes, adjust to the voltage level, and put two test leads on the voltage points to be measured, such as one live wire and one neutral wire.
