Hioki portable power meters and analyzers are best in class power measuring instruments for measuring single to three-phase lines with a high degree of precision and accuracy. The 3197 is a handheld power quality analyzer for monitoring and recording power supply anomalies, allowing their causes to be quickly investigated.
| Measurement line type | Single-phase 2-wire, single-phase 3-wire, three-phase 3-wire, three-phase 4-wire |
|---|---|
| Measurement range | [Voltage] 600.0 V AC, [Current] 500.0 mA to 5.000 kA AC (depends on current sensor in use), [Power] 300.0 W to 9.00 MW (depends on combination of current range and line type) |
| Basic accuracy | Voltage: ±0.3 % rdg. ±0.2 % f.s. Current: ±0.3 % rdg. ±0.2 % f.s. + current sensor accuracy Active power: ±0.3 % rdg. ±0.2 % f.s. + current sensor accuracy (at power factor=1) |
| Measurement items | 1. RMS Voltage and Current (200 ms calculation) 2. Voltage (1/2) RMS: one cycle calculation refreshed every half cycle 3. Current (1/2) RMS: half-cycle calculation 4. Frequency 5. Active Power/ Reactive Power/ Apparent Power/ Power Factor/ Displacement Power Factor/ Active or Reactive Energy Consumption 6. Demand (Active or Reactive power) 7. Up to 50th Harmonic Analysis (Time series measurement or recording is not available) 8. Peak Voltage and Current 9. Total harmonic voltage distortion ratio 10. Voltage Unbalance Factor 11. K Factor (Time series recording is not capable) 12. Total harmonic current distortion ratio (Time series recording is not available) |
| Event Detection | 1. Voltage Swells (Rise), Voltage Dips (Drop), Interruptions: RMS value detected using voltage (1/2) measured every half cycle 2. Inrush Current: RMS value detected using current (1/2) every half cycle 3. Transient Overvoltage: 50 Vrms or more detection, 10 to 100 kHz 4. Timer: Detect events at preset intervals 5. Manual: Detect events when keys are pressed |
