1. Press "SET" key to switch display categories, namely, instantaneous electrical parameters → voltage subharmonic →
current subharmonic → complex rate → instantaneous electrical parameters
；
2. In a certain display class, the display is displayed by pressing the " " and " " keys;
3. In the instantaneous electrical parameters, voltage sub-harmonics, and current sub-harmonics,the energy can be viewed
through the “ ” and “ ” keys, which are:integrated active energy → positive active energy → negative active energy →
integrated reactive energy → positive reactive energy → negative reactive energy → first quadrant reactive energy →
second quadranteactive energy → third quadrant reactive energy →fourth quadrant reactive energy
