F luke’s three-phase power logger, the 1738, gives users the data needed to make critical power quality and energy decisions in real-time. It has more power quality measurement capability than its predecessor, the Fluke 1730, a pure ener- gy logger. For both basic power quality studies and energy studies, the 1738 enables users to meas- ure, capture and log all relevant characteristics of electric power and gives access to management to analyse large data sets. With the 1738 and Fluke Connect mobile app and software, users can access, measure, capture, log and share all relevant characteristics of electric power data remotely with the team/management. Access to the logger through WiFi maintains safer working distances and allows critical decisions to be made in real-time and reduces the need for pro- tective equipment, site visits and check-ins. Specifically engineered to conduct energy stud- ies and basic power quality logging, the 1738 auto- matically captures and logs over 500 power quality parameters for more visibility into the data need- ed to optimise system reliability and savings. The unit includes advanced limit based analysis (uses EN510160 limits), the capability to connect two Fluke Connect devices for logging of supplementa- ry parameters and a WiFi/ Bluetooth (BLE) dongle. The 1738’s optimised user interface, flexible current probes, and an intelligent measurement verification function, reduces measurement er- rors by digitally verifying and correcting common connection errors. This makes setup easy and re- duces measurement uncertainty. Users can chart and graph measurements to help identify issues and create detailed reports with the included Fluke Energy Analyze Plus software package. Optional- ly, IEEE519 Reports can be created, giving more insight into harmonic levels, voltage and current distortion, and load current (licence required). 1738’s Key features: • Key measurements: Simultaneously meas- ures log voltage, current, power, harmonics and associated values

• Measures all three phases and neutral: With four flexible current probes included • Connectivity on a portable power logger: View data locally on the instrument, via the Fluke Connect App or through the facility’s Wi- Fi infrastructure • Comprehensive logging: 20+ separate log- ging sessions can be stored on the instru- ments. (All measured values are automatically logged for measurement trends) • Captures dips and swells: Includes event waveform snapshot, along with date, times- tamp and severity to help pinpoint potential root causes of power quality issues • Complete ‘in-the-field’ set-up through the front panel or Fluke Connect App: No need to return to the workshop for download and set-up or to take a computer to the electrical panel • Convenient instrument powering: Power instrument directly from the measured circuit eliminating the need to find a power outlet while allowing the instrument to be secured safely inside electrical panels • Fully integrated logging: Connect other Fluke Connect devices to the 1738 to simulta- neously log up to two other parameters, virtu- ally any parameter available on Fluke Connect enabled digital multimeters • Two USB ports: One for PC connection − another for quick, simple data download to standard USB thumb drives, or other USB devices for in-place, undisrupted logging • Highest industry safety rating: 600 V CAT IV/1 000 V CAT III • Security: Safeguard from theft with an optional hefty, durable Kensington lock • Power Quality Analyze ap-
