Use internal RMS voltage reference instead of voltage input for average active power.
0 = Use voltage input.
1 = Use internal RMS voltage reference, VFRMS.
E1, E2, and E3 alternate output mode (when enabled by E2MODE).
00 = E1, E2 = P1AVG, P2AVG
01 = E1, E2 = S1, S2
10 = E1, E2 = Q1AVG, Q2AVG
11 = E1, E2 = Q1WB, Q2WB
E2 Output Mode
00 = Energy Sign
01 = Total Apparent Energy
10 = Not Used
11 = Enable E1MODE
High-pass Filter Enable for Energy Channel 2
00 = No Filter
01 = HPF on Current, PMF on Voltage
10 = HPF on Voltage, PMF on Current
11 = HPF on both Voltage and Current
High-pass Filter Enable for Energy Channel 1
00 = No Filter
01 = HPF on Current, PMF on Voltage
10 = HPF on Voltage, PMF on Current
11 = HPF on both Voltage and Current
E3 Output Mode (with E1MODE disabled)
00 = Total Reactive Energy (default)
01 = Power Fail Monitor
10 = Voltage1 Sign
11 = Total Apparent Energy
E3 Output Mode (with E1MODE enabled)
00 = Power Fail Monitor
01 = Energy Sign
10 = Not Used
11 = Not Used
Positive Energy Only. Suppresses negative values in P1AVG and P2AVG. If a negative value
is calculated, zero will be stored instead.
Enables automatic line frequency measurement which sets Epsilon every time a new line
frequency measurement completes. Epsilon is used to control the gain of the 90 degree
phase shift integrator used in quadrature power calculations.
