Request a factory inspection form for diodes, resistors, transformers, capacitors, IC chips, transistors, a word document like the following

Circuit boards are complex, and all component measurements are unreliable, and no component can be reliably judged.

Usually, the measurement of "open circuit" or "high resistance" is credible, and the measurement of "short circuit" or "low resistance" is not credible, because the measurement of "short circuit" or "low resistance" is not credible. "




Open Circuit is the most reliable way to measure the resistance of a circuit breaker.
