🔥 Pain Points You’re Actually Facing
⚠️ Unstable or inaccurate power output can affect IoT device testing and lead to unreliable validation results
⚠️ Small standby-current changes are difficult to observe, making low-power IoT device evaluation inefficient
⚠️ Limited current measurement resolution makes it difficult to analyze sleep-mode and low-load power consumption
⚠️ Repeatedly adjusting voltage and current for different IoT test conditions wastes development time
⚠️ Incorrect voltage, excessive current, or accidental short circuits may damage sensitive IoT prototypes and development boards
⚠️ Accidental panel operation can change test parameters during long-duration device testing
⚠️ Coarse adjustment makes it difficult to fine-tune the power conditions required for embedded and low-power devices
⚠️ Without real-time voltage and current trend visualization, abnormal startup and power-consumption behavior is harder to identify
