Product Description
The YOKOGAWA WT310HC is a fifth-generation digital power meter from Yokogawa Electric, part of the WT300 series with single-phase input and high-current capabilities. Designed for high-precision power measurements, it supports wide-range signal analysis (DC to 100 kHz), making it ideal for energy efficiency testing of inverters, power supplies, and appliances. The compact half-rack design, multi-interface communication (USB/GPIB/RS-232/Ethernet), and free analysis software enable efficient deployment in both labs and production lines.
Key Features
-
High Precision and Wide Frequency Range: Basic accuracy of ±0.1% of reading, with DC measurement frequency range from 0.5 Hz to 100 kHz for stable transient signal capture.
-
Dual Current Range Support: Handles up to 40 Arms high current (WT310HC) and as low as 50 μA low current (WT310), covering tests from weak signals to high-power devices.
-
Simultaneous Multi-Parameter Measurement: Performs conventional power analysis, harmonic testing (optional), and integral energy calculations concurrently without mode switching, improving efficiency.
-
High-Speed Data Refresh: Up to 10 readings per second for rapid dynamic load analysis and shortened test cycles.
-
Auto-Ranging and Filtering: Automatic range switching in integral mode eliminates repetitive testing; line filters suppress noise interference for accurate data.
-
Flexible Connectivity and Software: Standard USB, GPIB (or RS-232) interfaces, optional Ethernet; includes WTViewerFreePlus software for real-time display/saving of waveforms, harmonic bar graphs, and trend charts.
