Features
The WT300 series digital power meters offer users the high performance and reliability customers have come to trust from Yokogawa.
The WT300's enhanced specifications and its wide range of functions let you handle all your measurement applications from low-frequency to high-frequency inverters using a single power meter.
First in Class:
Auto ranging function available in selected ranges.
The auto-range function is used to select or change the range automatically in specific ranges. This results in shorter range changing times, allowing more quick and efficient testing.
First in Industry:
Integration measurement auto ranging function.
Typically, when power meters operate in an integration mode to measure power consumption and standby power, the measuring ranges need to be fixed. However, if the level of the input exceeds the maximum of the selected range, the test will need to be repeated. The WT300 Series has a high speed automatic ranging capability in integration mode, which removes the need to repeat any test.
