3 From minute standby power to rush current for motors Applications that efficiently evaluate electrical equipment □ Common features of the 3331 and 3332 Measurement of rush current during device start-up Measurement of the current waveform wave peak is possible, and if the peak hold function is used, wave peak detection of the motor rush current waveform (Max. 90A) and the maximum value of the effective value can be done. RMS response approx. 0.2 sec. HIOKI 3331 POWER HiTESTER Օ Measurement of the RMS value for industrial frequency components. The average rectified effective value indicator...

4 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 complte 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. ration with EXCEL* *EXCEL is a registered trademark of Microsoft Corporation. »».n.--- saaaaaa?ll ^aaaaaa軮ii saaaa|⢮l...

5 Phase diffrence between voltage and current/Correlation function with other parameters Fluctuation state analyzed in clear waveforms. □ 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.
