About This Manual
This manual contains instructions for the 39 and 41B Power Harmonics
Testers (hereafter referred to as the Tester). All information applies to both
models unless otherwise indicated.
Uses for the Tester
You can use the Tester to measure voltage and current inputs at power line
and harmonic frequencies. Using these inputs, the Tester automatically
calculates power and a wide range of other measurements useful in
determining harmonic distortion levels and sources. The Tester can display
power calculations in either a single-phase or a 3-phase readout.
These capabilities allow you to monitor power quality before and after an
installation, troubleshoot a power distribution system, and (with Model 41B)
print out or download data for additional analysis.
The Tester is both a harmonics measurement tool and a power meter or
digital multimeter. You can use the Tester to measure voltage events
(undervoltage, overvoltage, line outages, and neutral to ground levels),
current levels, or to measure power levels. Fundamental frequency
measurements (to 100 Hz) and harmonic frequency measurements (to about 2
kHz) are also possible.
The Tester cannot measure frequencies above about 2 kHz. (Use the
ScopeMeter test tool to measure fast power transients.)
