Fluke 1738

Fluke 1738 – Overview

The Fluke 1738 is a high-performance power quality logger designed for monitoring and diagnosing three-phase electrical systems. It includes four flexible current probes (for three phases + neutral), offers a vivid color touchscreen for field use, built-in logging of hundreds of parameters, and advanced event capture features such as waveform snap shots to catch power quality disturbances. Ideal for energy studies, power quality analysis, and long-term monitoring.

Key Features

• Measures all three phases plus neutral with four flexible current probes

• Logs extensive power quality parameters: voltage, current, harmonics, total harmonic distortion, active/reactive/apparent power, power factor, unbalance, etc.

• Captures dips, swells, inrush currents, and provides waveform snapshots with timestamps

• Color touchscreen allows real-time viewing and operation in the field

• Intelligent interface helps verify connections and reduce measurement error

• Integration with Fluke Connect® and Energy Analyze Plus software for reporting and data analysis

• Multiple logging sessions stored onboard; review data before download

• Can be powered directly from measured circuit; supports different voltage input options
