DESCRIPTION:

The Yokogawa WT310 Digital Power Meter is a compact single-phase precision power analyzer designed for accurate AC and DC electrical power measurement across laboratory, R&D, production, compliance, and energy efficiency testing environments. The instrument supports simultaneous measurement of voltage, current, power, frequency, harmonics, and integration parameters for electrical device evaluation, standby power testing, inverter analysis, power supply development, battery systems, and industrial energy analysis applications.

The WT310 utilises a high-speed digital sampling architecture with 16-bit A/D conversion and sampling rates up to 100 kS/s, supporting waveform analysis across a frequency range from DC and 0.1 Hz up to 100 kHz. The instrument provides basic power accuracy from 0.1% of reading with fast data update rates down to 100 ms for rapid production and engineering test workflows.

Designed for high dynamic range measurement applications, the WT310 supports voltage inputs from 15 V to 600 V and direct current measurement ranges from 5 mA up to 20 A RMS with crest factor capability up to 300. The instrument can simultaneously measure AC/DC parameters, harmonics, THD, and integration values without changing operating mode, making it suitable for IEC62301, Energy Star, SPECpower, UPS, and standby power compliance testing.

The compact half-rack architecture incorporates USB connectivity as standard together with selectable GP-IB or RS232 interfaces and optional Ethernet/Modbus TCP support. Integrated filtering functions, auto-ranging capability, and WTViewerFreePlus software support automated data logging, waveform monitoring, parameter analysis, and report generation for engineering and production environments.
