Use internal RMS voltage reference instead of voltage input for average active power.
E1, E2, and E3 alternate output mode (when enabled by E2MODE).
E2 Output Mode
High-pass Filter Enable for Energy Channel 2
High-pass Filter Enable for Energy Channel 1
E3 Output Mode (with E1MODE disabled)
E3 Output Mode (with E1MODE enabled)
Positive Energy Only. Suppresses negative values in P1
Enables automatic line frequency measurement which sets Epsilon every time a new line
0 = Use voltage input.
1 = Use internal RMS voltage reference, VF
