Description
The Fluke 1738/EUS is the advanced version of Fluke’s three-phase power logger, recording voltage, current, power, harmonics and hundreds of related power quality values during energy studies. It can power itself from the circuit under test, measures all three phases plus neutral with the four included flexible probes, and captures dips, swells and inrush events with waveform snapshots. Electricians, facility managers and energy auditors use it for load studies, power quality surveys and verifying savings before and after upgrades.
Key features
- Logs more than 500 power quality parameters automatically
- Captures dips, swells and inrush current with waveform snapshots and RMS profiles
- Four flexible current probes for three phases and neutral
- Can be powered directly from the measured circuit
- Color touchscreen with guided setup and connection verification
- Fluke Connect app and Energy Analyze Plus software for review and reporting
Typical applications
- Energy consumption studies and load surveys
- Power quality troubleshooting at service entrances and panels
- Before and after verification of efficiency projects
- Sizing for new loads and capacity planning
