🔥 Pain Points You’re Actually Facing
⚠️ Inconsistent voltage or current can lead to unreliable test results when evaluating PCB circuits under different operating conditions
⚠️ Small voltage and current variations are difficult to observe, making circuit debugging and troubleshooting less efficient
⚠️ Low current measurement resolution makes it difficult to identify standby current, leakage-related current, and abnormal consumption
⚠️ Repeatedly setting voltage and current for different boards and circuit conditions slows down testing and validation workflows
⚠️ Incorrect voltage, excessive current, or accidental short circuits can damage sensitive PCB components and prototypes
⚠️ Long-duration PCB testing requires stable output without accidental changes to test parameters
⚠️ Coarse adjustment makes it difficult to precisely set voltage and current conditions for sensitive circuits
⚠️ Without visual voltage and current trend information, abnormal circuit behavior can be harder to identify
