b. Once the MAG. button is pressed, the waveform will be shown in the left part in
LCD, and the 1
st
to 50
th
order harmonics will be shown in the right part in LCD.
c. The positive and negative peak values will be shown in the waveform (Vpk).
d. The true RMS value and total harmonic distortion (THD-F) of voltage or current
will be shown under the waveform.
e. The cursor (
↑
arrow) will point to the current order of harmonics. The
frequency (HZ) will be displayed next to the cursor. The percentage of
harmonics (%) will be displayed below the cursor. The magnitude of the
harmonics (V or A) or phase angle will be displayed next to the %.
f. To move the cursor to next harmonics, press the
◄
or

button.
g. To see the next page of 51

order.
NOTE:
If the waveform is chopped off at the peak or too small in the LCD, press the
RANGE button to select HIGH or LOW range for better display. The range
indicator is a symbol after the unit of RMS value, L or H.
