ENTRY DESCRIPTION
ST PHASE Selects the start phase angle for output changes made to either
voltage or frequency. This allows changing the output at a specific
phase angle. The Output on/off key also uses this phase angle
setting to program the output voltage up to the set level after the
output relay is closed. The default value for this field is RAND. To set
the start phase angle, set the cursor to the ST PHASE field and use
either shuttle knob to adjust between ± 360°. To set to RAND, use
the BACK key.
