3331, 3332 POWER HiTESTER
Power measuring instruments
Accurate evaluation of consumption power of electrical products
As efficient use of energy for household and office equipment becomes more and more essential, the new 3332 POWER HiTESTER does the job by offering a wide range of power measurement from standby to normal usage. The 3331 POWER HiTESTER is capable of evaluating 3-phase devices, such as industrial air conditioners and refrigerators, or single-phase, large-scale devices. Both power testers deliver high accuracy of 0.2% (45 to 66Hz), direct input up to 50A, and a broad bandwidth from 1Hz (the 3331 from 10Hz) to 100kHz. System construction is made easy with these compact, lightweight and reasonably priced tools, which come equipped with an external interface as a standard feature. The 3331 and 3332 can be used as a measuring component for a wide range of purposes, from research and development to equipment evaluation.

Special Features of the 3332
Measurement of standby power under 1W
Current input 1W or less can be precisely measured (guaranteed accuracy range is from 7.5mW) by employing the CT method (input resistance under 2m) for minimal instrument damage for current input, and with 150.000mW (150V-1mA range) in full scale as the highest sensitivity range for 100V devices. In addition, with guaranteed accuracy from 1Hz, the 3332 is also compatible with intermittent oscillating devices, such as videos.
Precise calculations of minute standby power
When the 150V/1.0000mA range is selected, integration from 000.000mWh can be performed. Low numbers/units are automatically switched to a 6-digit display, allowing measurement in high resolution.

Comparative decision function that can be used on the production line
Two items can be chosen from among voltage, current, power (active, reactive, apparent), peak current, power factor, phase angle, frequency and integration value for simultaneous comparative decisions. In addition to Hi/In/Lo LED lamps, decision results are output to contact points. Up to 10 conditions can be stored, a powerful function to reduce repetitive steps on small output/multi-product lines.

Application example using the GP-IB/RS-232C interface
The 3331 and 3332 are equipped with the GP-IB and RS-232C interfaces as standard features, allowing complete control from a computer (except for turning the power supply ON/OFF). In addition, measurement data can be directly downloaded into commercially available spreadsheet software on a computer using application software, making the troublesome creation of test result charts easy, and supporting effective data management.

Keeping standby power of household electrical equipment in the range of 1W and below
A plan for reducing contributions to global warming by raising the efficiency of electrical energy used by household and office equipment must take standby power into consideration. In the Japanese domestic market, precise measuring of minute standby power is needed, especially for manufacturers of audio/video devices, in order to follow a policy of keeping standby power under 1W.
Raising the efficiency of electrical energy consumption to meet the needs of the time
Energy Star Program
The 1995-10 International Energy Star Plan is a program developed between the United States and Japan with the goal of universally advancing energy efficient office products, such as copy machines, printers, and fax machines.

Application example of monitor, analog, and D/A output
The 3331 and 3332 are capable of simultaneous output of voltage and current waveforms as well as the active power level, and when connected to a HIOKI MEMORY HiCORDER or Hybrid Recorder, events ranging from long-term fluctuations to transient phenomena (only with MEMORY HiCORDERs) can be recorded. Select one other measurement item (apparent power/reactive power/power factor/integration power capacity/frequency, etc.) to output from the D/A to conveniently record long-term fluctuations. 3-phase voltage/current monitor output (for the 3331)

MEMORY HiCORDERs To record monitor / analog / D/A output
Recording is made easy with the trigger function in the MEMORY HiCORDER, which records the rush current when a device is started, and with the recording mode, records fluctuations of power/integration values/frequency. Examination and analysis of correlation functions for each factor, including temperature, is another strong feature.
