SEW Portable Analogue Meters ST-2000A AC/DC Ammeter are moving coil or Rectifier instrument. ● Principle : Moving coil type ● See Datasheet for Ranges available ● Accuracy : ± 0.5% F.S. ● Scale Length : Approx. 135mm(5-3/8”) ● Weight : Approx. 1.7kg ● Dimension :196(L) x 170(W) x 87(D)mm ● Case Material : Bakelite with glass window ● Meets : ST-2000V AC/DC Voltmeter are moving coil or Rectifier instrument. ● Principle : Moving coil type ● See Datasheet for Ranges available ● Accuracy : ± 0.5% F.S. ● Scale Length : Approx. 135mm(5-3/8”) ● Weight : Approx. 1.7kg ● Dimension :196(L) x 170(W) x 87(D)mm ● Case Material : Bakelite with glass window ● Meets : ST-2000 Hz Portable Frequency Meter. The Hz meters use a frequency-to-DC current transducer which drives a high sensitivity moving coil type indicator. It features accurate frequency measurements without noticeable influence of line voltage fluctuation (50 to 300V) or waveform distortion. ● Principle : Frequency sensing transducer ● See Datasheet for Ranges available ● Accuracy : ±0.5% of full scale value on 45 to 65 Hz range ±0.5% of full scale value on 0 to 100Hz range ±0.5% of full scale value on 0 to 500Hz range ● Scale Length : Approx. 135mm (5-3/8”) ● Case Material : Bakelite with glass window ● Meets : ST-2000 COS Portable Power Factor Meter. The PF 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. ● Principle : Phase angle sensing transducer ● See Datasheet for Ranges available ● Rated Accuracy : ±3% phase angle ● Scale : Power Factor：Lead 0 – 0.3 – 1.0 – 0.3 – 0 Lag Power Angle： Lead 90° – 0° – 90° Lag ● 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 ● Meets : ST-2000 W Portable Wattmeter The wattmeter is electrodynamometer type, this instrument is highly reliable, and designed for use in laboratories or factories for precision measurement of power at AC and commercial frequencies 45-65Hz. ● Principle : Electrodynamometer type ● See Datasheet for Ranges available ● Accuracy : ±0.5% of full scale ● Scale Length : Approx. 135mm(5-3/8”) ● Scale Divisions : 120 ● Frequency Ranges : AC 25 to 1000Hz (COSØ=1.0) (suitable for DC) AC 25 to 500Hz (COSØ=0.2)
