Demand Measurement up to 4 Circuits and Simultaneous Harmonics Analysis


Not provided in PW3360 and PQ3100: 4-circuit measurement (single-phase 2-wire), high-speed data storage, and high-speed D/A output.

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).

Key Features

  • Simultaneously measure demand and harmonic waveforms that share the same voltage line over 4-circuits
  • Data can be saved onto a PC card
  • High-speed and continuous processing to measure individual waveforms
  • High-speed D/A output for analog graph recording (Model 3169-21)

Model No. (Order Code)

3169-20 Discontinued, Main unit, clamp sensor is sold separately
3169-21 Discontinued, With D/A output function model
Note: Optional current sensor is necessary to measure current or power parameters. To store measurement data, use only the guaranteed PC cards sold by Hioki.

To measure multiple systems simultaneously

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.
