ST-2000Cos Portable Analog Power Factor Meter is used for measurement in single-phase and balanced three phase circuits.
From a phase discriminating circuits, the output of the builtin transducer produces a DC proportional to the phase between voltage and current to operate the DC indicator

PF (1Ø, 3Ø) meter

Principle: Phase angle sensing transducer.
Rated Accuracy: ±3% phase angle.

Scale:
Power Factor: Lead 0 – 0.3 – 1.0 – 0.3 – 0 Lag.
