FAQs
Q1: Why do I need a 100kHz testing frequency?
A: Small inductors and precision capacitors behave differently under varied frequencies. Specifically, testing them at low 1kHz signals yields highly inaccurate data. Therefore, the 100kHz high-frequency output is absolutely critical. Ultimately, it reveals the true impedance and ESR characteristics of sensitive components perfectly.
Q2: What is the gold-plated short-circuit plate used for?
A: Environmental humidity and test lead resistance cause tiny measurement errors naturally. Thus, performing clearance calibration before testing is highly recommended. First, you insert the gold-plated plate to short the terminals. Next, the machine clears the residual impedance automatically. Consequently, your subsequent tests remain flawlessly precise.
Q3: Can I test SMD (Surface Mount) components with this?
A: Yes, you certainly can. First, the unit includes high-quality alligator clips natively. However, for tiny SMD components, you can attach optional SMD testing tweezers securely. As a result, diagnosing modern miniature circuit boards becomes incredibly simple and efficient.
Q4: Will it work continuously if I plug it into the wall?
A: Yes, it supports continuous operation perfectly. Specifically, it features an intelligent automatic power-switching circuit. Therefore, when you plug in the Mini-USB cable, it draws power directly from the adapter. Ultimately, you save battery health during long factory production line shifts.
