GT4505 AC circuit integrated experiment instrument application

GT4505 AC circuit comprehensive experimental instrument description

[Overview]

The GT4505 AC circuit integrated tester is designed and manufactured with a universal and modular open structure. It has the advantages of reasonable design, fine production, generous shape and easy operation. The GT4505 AC circuit comprehensive experiment instrument includes all the components required for AC circuit experiments, including: three independent resistance bridge arms (Ra resistance box, Rb resistance box, Rn resistance box), standard capacitor Cn, standard inductor Ln, The measured capacitance Cx, the measured inductance Lx and the signal source and the AC finger zero meter.

These open modular components and components, together with high-quality dedicated patch cords, allow students to connect themselves to complete the study of the steady-state and transient characteristics of RC, RL, and LCR circuits. The response process of the sine wave and the step wave of the circuit, the second-order circuit, and the working principle of the integral circuit and the differential circuit; can form various types of AC bridges, which is very suitable for teaching experiments.
