HIOKI 3169-21

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 3169 is clamp on power meters designed to measure demand and harmonics, which are important for energy management, as well as basic electrical parameters such as voltage, current, power, power factor, and integrated power (watthours).

In addition to performing simultaneous measurement for up to four systems (single-phase, 2-wire) with a common voltage, you can set the current range individually for each system. Setting the most suitable current range for both large and small loads allows you to acquire more accurate measurements.

Measurement line & number of circuits: Single-phase 2-wires (4 circuits), Single-phase 3-wires (2 circuits), Three-phases 3-wires (2 or 1 circuit), and Three-phases 4-wires (1 circuit). Note: 50 or 60 Hz, and that share the same voltage line

Measurement items: Voltage, Current, Active/ reactive/ apparent power, Active/ reactive power integration, Power factor, Frequency, Harmonic waveform value (up to 40th order)

Measurement range: [Voltage] 150.00 V to 600.00 V AC, 3 ranges, [Current] 500.00 mA to 5.0000 kA AC (depends on current sensor in use), [Power] 75.000 W to 900.00 kW (depends on combination of voltage, current range, and measurement line)

Basic accuracy:

• AC Voltage: ±0.2 % rdg. ±0.1 % f.s.
• AC Current: ±0.2 % rdg. ±0.1 % f.s. + current sensor accuracy
• Active power: ±0.2 % rdg. ±0.1 % f.s. + current sensor accuracy (at power factor = 1)
• Clamp on sensor: 9661: ±0.3 % rdg. ±0.01 % f.s. (different from each sensor models)

Measurement method: Digital sampling, PLL synchronization or 50/60 Hz fixed clock

Display refresh rate: 2 times /sec (except when a PC card accessing, or RS-232C communications)

Data save interval:

• Standard interval: 1 sec to 30 sec, 1 minute to 60 minutes, 13 selects
• Fast interval: A single waveform, or 0.1, 0.2, or 0.5 sec (at instant value only)

Frequency characteristics: Fundamental waveforms up to the 50th order ±3% f.s. + measurement accuracy (of a 45 to 66 Hz fundamental waveform)

Other functions: Error connect check, language selection, display hold, setting backup, power shut off management, key lock, [3169-21 only] D/A output 4 channels, (±5 V DC f.s.)

Power supply: 100 to 240 V AC, 50/60 Hz, 30 VA max.
