View harmonic (APM810 only): Press
◀▶
key on the main screen until the current measurement data display area shows THD, the
measurement data area shows THD, HARM, and press the enter key. Press the ◀▶ key to view the total harmonic distortion of the
voltage, the total odd harmonic distortion of the voltage, the total even harmonic distortion of the voltage even, the total harmonic
distortion of the current, the total odd harmonic distortion of the current, and the total even harmonic distortion of the current. After
you press the enter key at the total harmonic distortion of voltage (or current) interface, you can view the subharmonics.
