Features
The WT300E's wide range of functions and enhanced specifications, allows handling of all the measurement applications from low frequency to high frequency inverters using a single power meter.
Accuracy with fast display and update rate:
The WT300E series with the fast display update rate of 100ms, offer’s engineers a short tact time in their testing procedures. The basic accuracy for all input ranges is 0.1% rdg + 0.05% rng (50/60Hz) and DC 0.1% rdg + 0.2% rng.
Simultaneous Measurement:
U/I/P/Freq/Integ(+/-)/Harmonics components/ THD with max. 100ms cycle.
In addition to standard power measurements, the WT300E series measures all DC and AC parameters. Additionally, the WT300E series can measure harmonics and perform integration simultaneously without changing the measurement mode. The accompanying WTViewerFreePlus software can monitor and save the 200 parameters used.
Auto ranging function available in selected ranges.
The auto-range function is used to select or change the ranges automatically, within specified ranges. This results in shorter range changing times, allowing more efficient testing.
Auto Ranging Function For Integration Measurement
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 WT300E Series has a high-speed automatic ranging capability in integration mode, which removes the need to repeat any test.
Bandwidth: DC and 0.1Hz to 100 kHz (WT310EH is up to 20 kHz for 40A).
Direct Input: Maximum direct input of up to 600V and 20A, or 40A (incase of WT310EH). The wide current input ranges on the WT310E series, give users the option to measure current as low as 50 micro-Amps to as high as 40Arms (incase of WT310EH).
High-speed data update (up to 10 readings per second.)
