exempt from liability.
The device is designed exclusively for the
described application.
This user manual should be read carefully by
the technician / qualified personnel and the end
user. This manual should be kept with the
power meter and made available to relevant
personnel. In case of any obscurities or
questions, regarding this manual or the product,
please contact Compressed Air Alliance.
Note: The power logger must be maintained.
Incorrect maintenance may void the warranty or
result in incorrect measurement values, which
can lead to wrong results.
Electrical Safety
Users should be suitably qualified, licensed and
experienced to use this product. Incorrect use
or installation could result in serious injury or
death. Compressed Air alliance is not liable for
any injury or incident occurring from using this
product.
Using the Power Meter
•The power meter is not to be used in
explosive areas.
•Do not exceed or undercut the permitted
operating parameters.
•Do not exceed or undercut the permitted
storage parameters.
•See Specifications section for permitted
operating and storage parameters.
Note: any operation exceeding minimum or
maximum permitted parameters can lead to
malfunction and may lead to damage of the
power meter or personal injury. It may also void

POWER METER –POM400 USER MANUAL V1
Portable Power Meter
The portable power meter and data logger
measures current and voltage and reports real-
time RMS values for all 3-phases and neutral. In
addition, the power meter calculates power
factor, real power, reactive power, and more.
Why should you monitor
power?
Monitoring power can help you:
•Reduce operating and energy costs
•Improve understanding of energy usage (eg
spikes, variation, usage)
•Identify phase and voltage issues
•Identify power factor and harmonic issues
•Compare and challenge your energy bill
•Improve efficiency and reduce waste
•Monitor individual equipment usage or sub
system loads
This power meter is best
suited to
•3 phase or single phase measurements
•Where a portable solution is needed
•Temporary installations
Key Features
•Measure voltage, amps, frequency, power
factor, real power, reactive power, apparent
power and harmonics
•Built in display for easy reading and
configuration
•1 GB memory SD card, save up to 12 years
of data
•Battery powered or 5V DC Power supply
•Can be used for sub metering individual
equipment or sub loads
•Easy to install rogowski coil current
transducers (optional)
