Magnetic Core Characteristic Tester
Leave a Message
LS2736/LS2737 Magnetic Core Characteristic Tester (Voltmeter-Ammeter Characteristic Tester) is an intelligent testing instrument engineered for ferrite core and iron core sorting applications in compliance with IEC 62333-2 standards. This instrument functions as a general-purpose AC constant current source or AC millivoltmeter with a minimum resolution of 1μV. It simulates and measures the induced voltage generated by a single-turn winding in magnetic cores under specified operating frequencies and currents.
The instrument features both true RMS measurement mode and traditional average measurement mode. The true RMS mode provides high-accuracy measurements for distorted waveforms, while the average mode facilitates comparative data analysis, achieving dual functionality with exceptional cost efficiency. Additional advantages include rapid measurement speed, high precision, and excellent stability.
