Features
Improvement of basic power accuracy
The WT300E series provides a basic power accuracy of ±0.15% (50/60 Hz) on all measurement ranges. It is the most accurate power meter in the compact category. The influence at low power
factors is twice as good (0.1% of S) than the previous model.
Wide current ranges
The WT300E series cover broad ranges of current input from a few mA up to 40 A rms. It can measure waveforms which include both AC and DC. Users can use it from the low currents of
standby power to the high currents of induction cooking.
Fast display and data update rate
The fast display and 100 ms maximum data update rate of the WT300E series offers customers a short tact time in their testing procedures. Consistent Basic Measurement Accuracy for all input ranges.
Auto data update rate function for fluctuating input
Auto ranging function available in selected ranges
The auto-range function is used to select/change the range automatically in specific ranges.
This results in shorter range changing times and thus quicker andmore efficient testing.
The mode of Crest Factor “6A”
When "6A" is chosen as the Crest factor, the maximum rated input of the voltage and current becomes 260% of the range and up to 280% is displayable. When high resolution is required, users can prevent frequent current range changes by using this mode.
Automatic zero adjustment
The WT300E series compensates for any drift in the zero level by automatically performing a zero adjustment when the input ranges are changed. This is achieved in less than 100 ms and does not require the wiring to be disconnected.
