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
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.)
