Current Transformer (CT) Calibration

The AC voltage the CT outputs at its rated primary current. Do not exceed (at your expected maximum current) 0.5 V absolute to avoid damaging the ADE7953. For instance, if your maximum expected current is 30 A, a CT rated for 75A/1V may work.

The maximum primary (measured) current the CT is rated for, as printed on the CT body or datasheet (e.g. 30 A, 100 A). Must match your installed CT exactly.

Fine-tune correction applied on top of the base calibration (%). Use this to adjust for minor discrepancies, checking the current and active power against a known reference.
