Large storage capacity to accommodate power and harmonics data for individual
waveforms.-Supports energy saving measures that can be carried out from your PC.
Greater flexiblity for energy saving measures through
detailed measurement!
■
Reduce energy consumption by "1%"! Why not try analyzing your energy saving measures?
★
Save measurement details to PC card for extended measurements!

Unbalanced loads are an enemy to energy saving activities.
Solve your problems with careful management of power lines.
Why not try a shorter data management interval?
With the 3169-20/21, you can set the data recording interval to 1 minute. If you are unsure how
to proceed with energy conservation, you can use a large capacity PC card to save measurement
details, then use the data to create a load fluctuation graph and analyze this to help reduce wasted
power consumption.
Unbalanced 3-phase loads can result in a damaged power line.
To provide detailed management of measurements, the 3169-20/21 displays voltage and current
for all three lines even when measuring just two circuits (3P3W2M). Further, because the effective
power for each phase is displayed based on a virtual center point when measuring the voltage
and current for all three lines (3P3W3M), the units can also be used to implement energy saving
measures and power management systems.
Further, because you can save a variety of data, including simultaneous recording of power and
harmonics data, waveform data storage, and print-outs of the screen, these two new units help by
storing measurement details.

Identify even small amounts of power waste using individual waveform measurement
The 3169-20/21 can help turn you into a keen energy saving specialist.
These two new units allow you to measure power data by recording the RMS values for individual
waveforms.
s
By measuring just a few seconds of machine cycles or changes in operating patterns of facilities
such as manufacturing equipment, you can grasp power fluctuations over a relatively short amount
of time and view improvements in the form of numerical data. Gain unsurpassed energy savings by
achieving simple improvements around the work environment.
★
Harmonics cause wasted power
Did you think that harmonics and energy saving activities were unrelated?
Due to a spread in equipment that uses semiconductor control devices, such as inverters, power
quality has decreased. Also, power consumed in harmonic components is all wasted power.
Harmonic control and management are essential for energy conservation.
The degree of
distortion is obvious
in the voltage/current
display
Results can be easily processed using software such as Excel.

Improve energy-saving operations and create an energy-efficient facility
Why not try to improve your energy-saving measures using the 3169-21?
Using the D/A output (4 ch) function on the 3169-21, you can simultaneously record a variety of
measurement and control signals for equipment, such as the power fluctuation and temperature/flow
for individual waveforms, onto a HIOKI MEMORY HiCORDER or logger.
A slight reduction in power consumption due to changes in the inverter motor operating patterns or
temperature settings equals to an energy-saving effect.
The current direction
of harmonic waves is
obvious
The 3169-20/21 allows you to view changes that are hard to determine
from numerical data alone.
You can switch channels to easily check the harmonics for each circuit
★
To identify causal factors with harmonic measurements of multiple systems circuits
Accurate recording of
momentary fluctuations in
power, etc.
If production equipment malfunctions, power is wasted if repeated manufacture results in defective
products again.
If you think harmonics are causing malfunctions, you can simultaneously measure the harmonics
of individual circuits using multi-circuit measurement to obtain detailed information about the
occurrence of harmonics along with the current direction for each phase. Using the 3169-20/21 you
can accurately determine the relationship for harmonic inflow and outflow between power lines by
analyzing the data acquired simultaneously, and then devising energy-saving measures based on the
cause of the occurrence.
