Introduction
The 1742, 1746, and 1748 Power Quality Loggers (the Logger or
Product) are compact devices for technicians and engineers to
troubleshoot, quantify energy usage, and analyze power distribution
systems. The Product is compliant with international standards such
as IEC 61000-4-30 and IEC 62586. The Product can simultaneously
log up to 500 parameters and capture events to find intermittent and
hard-to-find power quality issues.
The included Energy Analyze Plus software enables thorough
analysis of the captured data and reporting according to national and
international standards such as EN 50160. All illustrations in this
manual show the 1748.
