Abstract
The paper describes an improved digital recorder system which is being used to measure accurately voltage, current, active, reactive and apparent powers and harmonic quantities for three phase sinusoidal and non-sinusoidal calibrations. The system has been designed to be used in the laboratory at the National Research Council of Canada (NRC) or transported on-site for tests in electrical utility facilities. Preliminary tests have shown that for sinusoidal waveforms, the accuracy of the voltage and current measurements of the digital recorder is better than 30 ppm and better than 50 ppm for active, reactive and apparent power measurements (with respect to full scale). The accuracy of the system for harmonic measurements is related to the harmonic content of the test waveforms and is estimated for individual tests.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
