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).
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.
