HST-2000Cos Portable Analog Power Factor Meter

ST-2000Cos Portable Analog Power Factor Meter (PF meter) is used for measurement in single-phase and balanced threephase 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.
● Principle: Phase angle sensing transducer.
● Rated Accuracy: ±3% phase angle.
● Effective Power Factor Measuring Range: Lead 0.5 – 1.0 – 0.5 Lag.
● Scale Length: Approx. 135mm(5-3/8”).
● Frequency Influence: Within ±1.5° phase angle at 45 to 65Hz.
● Power Factor Scale: Lead 0 – 0.3 – 1.0 – 0.3 – 0 Lag.
● Power Angle Scale: Lead 90° – 0° – 90° Lag.
