This unit accepts an analog DC signal from a Power Factor transducer, ranging from 4-20mA, 0-1mA, 2VDC, 5VDC, and 10VDC.
It provides a bargraph and digital display of the reading in the format customary for Power Factor meters with the bargraph centered at PF=1.0.
Lead and lag are indicated by the circular bargraph extending clockwise (lead) or counter clockwise (lag) with cos(theta) scale markings from LAG 0.5 to 1.0 to LEAD 0.5.
The digital display provides a corresponding numeric readout of the same data with LAG represented by a negative sign.
