Use KMS40 cables only when within the 500 V AC specification limit.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: What is the best way to ensure long-term stability?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eA: Monitor the ambient rack temperature closely. Keeping operating environments below the threshold prevents cumulative temperature drift exceeding ±0.01%\/°C.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Which configuration mode is best for valve control?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eA: Use the [SETV] fallback mode for critical valves.
