The 3334 power meter is a single-phase direct access power meter that can be used for both AC and DC. Capable of measuring and accumulating effective power and current, corresponding to waveform peak measurement, ensuring high accuracy for up to 3 years. In addition, practical considerations were also taken into account when developing the product. In order to adapt to the use on the production line, LED displays with large numerical values and easy visibility were used, including voltage/current/active/apparent power/reactive/power factor/frequency/current accumulation/effective power accumulation/voltage waveform peak value/current waveform peak value/any four items during the accumulation period. Because 3334 is equipped with an RS-232 interface, 3334-01 comes standard with RS-232 and GP-IB interfaces, allowing for easy measurement and data management through a computer.
The most suitable for conducting power on experiments and measuring power experiments on household appliances and other products, researching and developing battery driven products and general electrical appliances such as office automation machines, and using them on production and inspection lines.

talent

• Capable of measuring the required measurement conditions for household appliances with high precision
  • 1-year accuracy (50/60HZ): ± 0.1% rdg. ± 0.1% fs
    
  • 3-year accuracy (50/60HZ): ± 0.1% rdg. ± 0.2% fs
• Can measure DC more accurately
  • 1-year accuracy: ± 0.1% rdg. ± 0.1% f.s
    
  • 3-year accuracy: ± 0.1% rdg. ± 0.35% fs
    In addition to pure DC loads, waveforms of AC components such as half wave rectification and mixed DC components can also be accurately measured.
• The accuracy guarantee period is 3 years, which is 6 times the long-term guarantee compared to our previous products (6 months for power meters), and is also a longer guarantee period compared to other power meters sold in the market (ensuring accuracy for 3 months to 1 year).
  
• Wide input range and ensuring accuracy
  • Voltage: can measure 0.15V~300V (consisting of 4 ranges of 15V/30V/150V/300V)
    
  • Current: capable of measuring 1m A~30A (consisting of 6 ranges of 100m A/300m A/1A/3A/10A)
    
  • Effective power: can measure 0W~9KW
    Because it can ensure accuracy over a wide range, it can correspond to the cumulative power of appliances such as refrigerators that are repeatedly turned on/off.
• High precision, long-term guarantee of low price added
  Compared to similar products with functions equivalent to 3334, the price is about 70% lower.
  
• The 4-channel analog output can correspond to the timing records required for product evaluation experiments.
  Three items of voltage/current/effective power are simultaneously output at DC ± 2V f.s. And, selecting one item between power/power factor/cumulative current/cumulative active power is also output at DC ± 2V f.s. Compared to the recorder link, changes in timing will be recorded more easily (data updated 5 times per second).
  
• By outputting waveforms through 3 channels, the instantaneous waveform of the tested motor during startup can be observed
  The instantaneous waveform of voltage/current/power can be simultaneously output at 1Vf. s. Compared with oscilloscope connections, it can observe the waveform of sudden incoming current and instantaneous power waveform.
  Sampling speed: approximately 74.4k Hz (1488 points/waveform at 50Hz, 1240 points/waveform at 60Hz)
  
• Capable of operating and managing data on a computer through standard configured connection ports.
  3334 is equipped with an RS-232 interface, while 3334-01 comes standard with RS-232 and GP-IB interfaces. After connecting to the computer, it can be easily controlled and operated. In addition, dedicated software for RS-232 can be downloaded from our company's website (free of charge), as it can directly read the values measured by 3334 on a computer and can be used as software to support data management.
