– Voltage harmonics test
Harmonics (1 through to 19) are measured and displayed in the chart as an absolute magnitude of the signal
or as a percentage of the fundamental frequency amplitude (the 1
st
harmonic h1). Absolute magnitude or
percent value display is chosen by parameter setting.

Use Voltage test connection scheme from MD 9273 Manual.
Measurement procedure
• Connect MD 9273 to the item to be tested and set Bluetooth® mode.
• Enter the Harmonics U function and wait for active Bluetooth® communication.
• Set Type parameter for display values of harmonics.
• Set charts Y value range within expected values (optional; could be set later).
• Start the continuous measurement.
• Stop the measurement.
• Save results (optional).
