| Product Overview |
|
HIOKI E.E. CORPORATION has released the new 3334 AC/DC POWER HiTESTER, a direct-input type power meter for use with single-phase AC and DC sources. Features include integrated measurement of effective power and current, waveform peak measurement, and high-accuracy operation backed by a three-year accuracy guarantee. The instrument's large, easily visible LED display, which was designed for use in product development and evaluation and on production and inspection lines, can display measurement results for any four of the following characteristics: voltage, current, effective power, apparent power, power factor, frequency, current integration, effective power integration, voltage waveform peak, current waveform peak, and integration time. Model 3334 features a standard RS-232C interface, while Model 3334-01 features standard RS-232C and GP-IB interfaces to simplify computer-based measurement and data management.
The 3334 AC/DC POWER HiTESTER is an ideal choice for applications such as energized testing and electric energy measurement testing of electric products such as household appliances, research and development of electric devices such as battery-powered products and office equipment, and production and inspection line measurement. |

| Advantages |
|
- High-accuracy measurement as required for the evaluation of products such as household appliances
- One-year accuracy (50/60 Hz): ±0.1% rdg, ±0.1% f.s.
- Three-year accuracy (50/60 Hz): ±0.1% rdg, ±0.2% f.s.
- Precise DC measurement
- One-year accuracy: ±0.1% rdg, ±0.2% f.s.
- Three-year accuracy: ±0.1% rdg, ±0.35% f.s.
In addition to simple DC loads, the 3334 can accurately measure waveforms with mixed DC and AC components such as half-wave rectified signals.
- The three-year accuracy guarantee is six times longer than previous HIOKI models (power measurement instruments typically have a six-month guarantee). This long-term guarantee also compares favorably to other commercially available power measurement instruments (which typically have accuracy guarantees ranging from three months to one year in duration).
- Guaranteed accuracy over a wide input range
- Voltage: Measurement from 0.15 V to 300 V (4 ranges: 15/30/150/300 V)
- Current: Measurement from 1 mA to 30 A (6 ranges: 100 mA/300 mA/1 A/3 A/10 A/30 A)
- Effective power: Measurement from 0 W to 9 kW
Since accuracy is guaranteed over a wide range, the 3334 can be used for integrated power measurement with devices like refrigerators that cycle on and off repeatedly.
- Combination of high accuracy, long-term accuracy guarantee, and low price
The 3334 costs approximately 70% of other commercially available power measurement instruments with similar performance.
- Four-channel analog output provides time history recording capability for product evaluation testing and similar applications. The 3334 can simultaneously output voltage, current, and effective power measurements at DC ±2 Vf.s. It can also generate output for any one of apparent power, power factor, current integration, and effective power integration measurements at DC ±2 Vf.s. Simply connect a recorder to record time series variations (data is updated approximately 5 times per second).
- Three-channel waveform output can be used to observe instantaneous waveforms, for example of electric motors at startup. The 3334 can simultaneously output instantaneous voltage, current, and power waveforms at 1 V f.s. Simply connect an oscilloscope to observe rush current waveforms and instantaneous power waveforms for equipment being tested.
- Sampling speed: Approx. 74.4 kHz (during 50 Hz operation, 1,488 points per waveform; during 60 Hz operation, 1,240 points per waveform)
- Standard interface(s) for computer-based data management: Model 3334 ships standard with a RS-232C interface, while Model 3334-01 ships standard with both RS-232C and GP-IB interfaces, enabling the instrument to be connected to a computer for simple measurement and control. Dedicated RS-232C measurement sampling software can be obtained from your local exclusive HIOKI distributor and used as a data management tool for loading 3334 measurement data onto a computer.
