The menu system
The top-level m
enu consists of the following submenus:
Harmonics Setup. Use these m enus to congure V, A, and W harmonics.
Distortion Setup
Minimum Hold Column
Maximum H old Column
Sum Results Column
Sum Voltage Formulas
Sum Current Formulas
Harmonics Setup
Use the Harmonics Setup to congure how quantities of harmonics are setup and
viewed as measurement results. Individual voltage, c urrent, and watts setups
provide congurable options dependent on the application and how to view the
results. There are separate voltage, current and watts menus that allow you to
set the following items:
Sequence. Odd and even or odd harmonic only (default Odd and even)
Range. 1 to 100 (default 7)
Format. Absolute or Percentage of the fundamental (default A bsolute)
Display Phase Angle. On o r Off (default On) (volts and amps only)
Selecting the harmonics results to display has no impact on the harmonic data
used in distortion calculations.
Please see the User Conguration section of this manual a bout update speed. (See
page 61, User Conguration.) The i nstrument is not able to calculate and display
100 harmonics on V, A, and Watts every 100 ms.
Distortion setup
The Distortion Setup menu provides access to the voltage and current distortion
factor (df), total harmonic distortion (THD), and telephone inuence factor
congurations.
Distortion factor. The distortion factor formula includes the effects of high
frequency and noise. This equation only produces a valid number if the RMS is
not less than the f undamental. If the fundamental is larger than the RMS the
display shows -----.
The equations are:
