Digital Power Meter accuracy level

For a given level of measurement accuracy of the Digital Power Meter, the error of the digital power meter under the specified conditions of use should be within the specified limits. The standard accuracy levels are: 0.05, 0.1, 0.2, 0.5, 1, 2, etc. The smaller the corresponding value of the accuracy level, the higher the measurement accuracy of the power meter. A level of 0.05 means that the error limit of power measurement is ±0.05%.
Note: Generally, the power meter is nominal under the conditions of rated voltage, rated current, rated frequency and power factor of 1. Factors such as low voltage, low current, frequency deviation, and low power factor will all cause the measurement accuracy of the power meter to decrease.
