Single Phase Mode Setup
For Single-phase mode current Calibration, the load must have the appropriate size. See next

Current Calibration Load Values
Full-scale current gain calibration is best performed at current levels that are around 90% of full
scale current. Since the ADF Series® has only a single voltage range, maximum RMS current is
available at 120Vrms L-N for each phase. For single-phase mode, the current is three times
higher. Thus, to obtain 90% of load current, resistor value that is sized to draw this current level
at around 120Vrms is required. Since the maximum current varies by model and phase mode,
the table below shows the recommended resistor values or resistive load bank settings.
