The unique
power analyzer with nominal relative accuracy

Almost all of the instrument's precision index is to reflect the error of the reference,
the accuracy index is only valid in the full range, that is, the accuracy and range is an integral whole.
To determine whether the results are accurate, the relative error is concerned.

For example: the instrument range is 15kV, the accuracy is 0.1%, we can not judge whether the results are accurate:
If the measurement is 15kV, the measurement accuracy is 0.1%; if the measurement is 1500V, the measurement accuracy is 1%;
If the measurement is 150V, the measurement accuracy is 10%; if the measurement is 75V, the measurement accuracy is 20%.

WP4000 variable frequency power transmitter built-in 8 automatic seamless conversion range,
The accuracy of measuring 75V to 15kV in the 15kV range power unit is 0.1%!

Large signal and small signal can be measured accurately!
