Explanation of the internal resistance of the digital bridge

High and low gear bridges and different system bridges have different internal resistances due to different design starting points and application ranges. For inductors with low permeability and anti-saturation, the internal resistance has little effect on the DUT. When the test level changes, the inductance and Q value are constant. For high-conductivity materials, such as nickel-zinc magnetic rings or other workpieces used in filters, the permeability is greatly affected by the outside, and the source current of the LCR or LCZ bridge has a greater impact on the μ value of these DUTs. For the 106X series bridge, its source internal resistance is relatively small. The design starting point is to check the degree of change of the material of the DUT under a certain driving current (ie, magnetic field strength). The change is reflected in the inductance and Q value, so as to check Defects such as iron loss of the material.

Technical Analysis of Counterfeit 3259 Transformer Tester

Recently, we have received numerous inquiries from customers to our Jinkaitai marketing department, inquiring about the sales price of GKT3259 transformer tester and understanding why 3259 from other companies in the market is cheap, and so on. What exactly is the reason for this? We are now conducting a technical analysis of counterfeit 3259 transformer testers (hereinafter referred to as "fake 3259") on the market regarding this issue. We hope that users can have a comprehensive and in-depth understanding and understanding of such counterfeit instruments, eliminate misunderstandings, and make a positive impression!
