Power factor regulator, at no load (only lighting) the varlogic indicates zero.

With light loading of 35~40 Amps for resistive lamps, it's normal to have an indication of unit power factor on the Varlogic as we have only resistive load. However, he said that it is not normal to see such a low value (77%) on the external meter and that you might need to check that external meter.
