Viewing THD/thd using the front panel

You can view THD/thd data using the front panel.

1.	Navigate to THD. On the THD/thd Select screen, press THD to display values that
	use the calculation method based on the fundamental harmonic, or thd to display
	values that use the calculation method based on the RMS value of all harmonics in
	that phase (including the fundamental).
	THD (or thd) display screens
		IEEE mode	IEC mode	Description
		Amps	I	Total harmonic distortion data for per phase and neutral currents.
		V L-L	U	Total harmonic distortion data line-to-line voltage.
		V L-N	V	Total harmonic distortion data line-to-neutral voltage.
2.	Press the current or voltage THD or thd values you want to view. The total harmonic
	distortion percentage values are displayed.
3.	Press  to return to the main display screens.

NOTE: Your meter’s Modbus map includes registers for total harmonic distortion data for integration into your power or energy management system.
