This user guide explains how to operate and configure a PowerLogic
™
Series 800 Power
Meter. Unless otherwise noted, the information contained in this manual refers to the
following power meters:
• Power meter with integrated display
• Power meter without a display
• Power meter with a remote display
Refer to “Power Meter Parts and Accessories” on page 5 for all models and model
numbers. For a list of supported features, see “Features” on page 7.
NOTE: The power meter units on the PM810, PM810U, and the PM810RD are functionally
equivalent.
Topics Not Covered In This Manual
Some of the power meter’s advanced features, such as on-board data logs and alarm log
files, can only be set up via the communications link using PowerLogic software. This
power meter user guide describes these advanced features but does not explain how to set
them up. For information on using these features, refer to your software’s online help or
user guide.
What is a Power Meter?
A power meter is a multifunction, digital instrumentation, data acquisition and control
device. It can replace a variety of meters, relays, transducers, and other components. This
power meter is equipped with RS485 communications for integration into any power
monitoring/control system and can be installed at multiple locations within a facility.
These are true rms meters, capable of exceptionally accurate measurement of highly
non-linear loads. A sophisticated sampling technique enables accurate measurements
through the 63rd harmonic

. You can view over 50 metered values, plus minimum and
maximum data, either from the display or remotely using software. Table 1–1 summarizes
the readings available from the power meter.

➀ Individual harmonics are not calculated in the PM810. The PM810 with PM810LOG, and the PM820,
calculate distortion to the 31st harmonic. The PM850 and PM870 calculate distortion to the 63rd harmonic.
