Fluke 1738

The Fluke 1738 includes enhanced features beyond the 1736, notably the WiFi/BLE to USB adapter for wireless connectivity with Fluke Connect mobile app and desktop software compatibility. The 1738 also includes the ability to connect other Fluke Connect devices to simultaneously log up to two additional measurement parameters from any Fluke Connect wireless digital multimeter or module, providing fully integrated logging capabilities for comprehensive power and environmental monitoring.

The Fluke 1738 features an intelligent measurement verification function that automatically checks connections and can digitally verify and correct common connection errors without disconnecting measurement leads. This reduces measurement uncertainty and setup time by identifying issues such as reversed phases or incorrect probe orientation. The optimized user interface provides quick, guided, graphical setup to ensure technicians capture the right data every time.

The Fluke 1738 includes four thin flexible current probes (i17xx-flex 1500 12-inch) that measure 150 A and 1500 A ranges with ±(1% + 0.02%) intrinsic accuracy. Optional probes include the i17xx-flex 3000 24-inch (300 A / 3000 A ranges), i17xx-flex 6000 36-inch (600 A / 6000 A ranges), and i40s-EL clamp (4 A / 40 A ranges). The thin probes are designed to easily get through tight conductor spacing in crowded panels.

Yes, the Fluke 1738 supports remote access through the Fluke Connect mobile app and desktop software, allowing you to view measurements and share data remotely with your team. This capability helps maintain safer working distances and reduces the need for protective equipment, site visits, and check-ins. The WiFi infrastructure license enables connection through existing network infrastructure for seamless remote monitoring and data transfer.

The Fluke 1738 can store more than 20 separate logging sessions internally, with all measured values automatically logged so you never lose measurement trends. The comprehensive logging captures over 500 power quality parameters, and data can be reviewed during logging sessions and before downloading for real-time analysis. Sessions can be easily downloaded via USB flash drive or wirelessly through the Fluke Connect app.

The Fluke 1738 captures dips, swells, and inrush currents with event waveform snapshots and high-resolution RMS profiles. Each event includes date, timestamp, and severity information to help pinpoint potential root causes of power quality issues. The unit measures voltage and current harmonics up to the 50th with accuracy meeting IEC 61000-4-7 standards, helping identify harmonic distortion that can damage critical equipment.

The Fluke 1738 includes Energy Analyze Plus application software for comprehensive download and analysis of energy consumption and power quality data. The software features powerful analysis tools with the ability to create customized reports in minutes, automated reporting functions, and the capability to quickly compare any measured parameters. Energy Analyze Plus helps communicate findings and solve problems to optimize system reliability and savings.

The Fluke 1738 offers voltage measurement with a range up to 1000 V and maximum resolution of 0.1 V. At reference conditions (23°C ±5°C, sinusoidal signal at 50/60 Hz), the intrinsic accuracy is ±(0.2% of reading + 0.01% of full scale). The unit adds a temperature coefficient of 0.1 times the specified accuracy for each degree C above 28°C or below 18°C, ensuring reliable measurements across the operating temperature range.
