Comparing the outputs of a monitor in mode 1 and a monitor in mode 4:
Mode 1:

hour t(sec) V1 VAngle1 V2 VAngle2 V3 VAngle3 etc.
0 1 276.143 -30.0397 276.143 -150.04 276.143 89.9603 etc.
0 2 276.143 -30.0397 276.143 -150.04 276.143 89.9603 etc.

Mode 4:

hour t(sec) Flk1 Pst1 Flk2 Pst2 Flk3 Pst3
0 1 276.143 -30.0397 276.143 -150.04 276.143 89.9603
0 2 276.143 -30.0397 276.143 -150.04 276.143 89.9603

The flicker monitor is outputing rms voltage and angle for each phase rather than instantaneous and short term flicker values.
Executing PstCalc on exported voltage values still works to generate pst values.

My code is below in case I'm missing anything:

Thoughts?
