Fluke 1738/B Advanced 3-Phase Power Logger
The Fluke 1738/B Advanced 3-Phase Power Logger (Basic version) automatically captures and logs over 500 power quality parameters, providing the essential data needed to optimize system reliability and savings. By recording voltage, current, power, harmonics, and other critical power quality values, this instrument is ideal for establishing energy consumption profiles, validating voltage quality, and identifying broader power quality trends.
Designed with advanced analytical capabilities, the Fluke 1738 allows network engineers and facility technicians to discover peak current from load switching and visualize dips and swells to pinpoint the root causes of power events. For extended field operations, the logger conveniently powers directly from the measured circuit.

Frequently Asked Questions
Q: Are current probes included with the Fluke 1738/B?
A: No, the Fluke 1738/B is the basic logger configuration and does not include current probes. This allows technicians to utilize existing compatible probes or select application-specific current sensors separately.
Q: How is the Fluke 1738 power logger powered during testing?
A: The instrument is powered directly from the measured circuit, which eliminates the need to find a standard power outlet when setting up monitoring at a panel or service entrance.
Q: What is the safety rating of the Fluke 1738 logger?
A: It is rated for 600V CAT IV and 1000V CAT III environments, making it suitable for safe use at both the service entrance and in downstream applications.
