I can't directly access or analyze specific PDF files like the Siemens 3AP1 FG manual, but I can point you to the most useful feature to look for—and how to find it yourself. Based on common high-voltage SF6 breaker manuals (3AP series), the most practically useful feature is: "SF6 Gas Density / Pressure vs. Temperature Compensation Chart" (or "Gas Density Monitor Correction Curve" )
