Harmonics Display
Press the THD/TDD, or H/ESC in the PM172EH, button. The THD/TDD LED
is illuminated. In the PM172EH, press the button again to move to the
individual harmonics, or to the harmonic power and energy displays. Use the
UP and DOWN arrow buttons to scroll through harmonics measurements.
Note that voltage harmonics readings are line-to-neutral in the 4LN3, 3LN3,
3BLN3, 4LL3, 3LL3 and 3BLL3 wiring modes, and line-to-line in all other
modes.
