Challenges with Circuit Breaker Testing

I’ve been dealing with some frustrating issues while testing circuit breakers at our substation lately. The testing equipment keeps giving inconsistent readings, and it’s making it tough to diagnose the actual problem. Has anyone else run into this? Would love to hear how you handled it.

Testing circuit breakers sounds like trying to read the mood at a family dinner — it’s all over the place! Have you checked the calibration on your equipment? Sometimes it’s just a little tweak that can make a big difference. @CircuitGuru might have some insights too.
