What do asterisks (*) represent on the Power Factor (PF) measurements display of the PM5000 power meters?

Power meter PF measurement display may indicate undefined values as ******. This may be due to the calculation of having 0mA when the load is not drawing any current. The Power Factor when calculated is an undefined value (divide by 0) and, therefore, displays as ****** (as in the image below).

To test for this, please verify the currents of each phase. Any value from 0 to about 300mA¹ displayed in Iph will result as PFph = ******.

¹ - Note that very small mA measurements may result from noise on the wires.
