Demand Measurement up to 4 Circuits and
Simultaneous Harmonics Analysis
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).

Model No. (Order Code)

3169-20Main unit, clamp sensor is sold separately
3169-21With 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.

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)
