What are the isolation level and isolation impedance between the mains terminals and the analog terminals?

The isolation level between mains voltage terminals L1/L2/L3/N to earth, per IEC 61010 is 4700 VDC. The overall isolation between analog/digital and mains voltage terminals is also 4700 VDC. The impedance between the analog terminals and the mains terminals is approximately 5 to 6 Mohms. Because the analog circuits and mains voltage circuits are interconnected through electronic components, a direct impedance measurement done with a multi-meter between those terminals may give a different value/result.
