5.5.3.7 Harmonic Distortion mode
In Harmonic Distortion mode, the meter displays the distortion percentage value
for the first 25 harmonics as well as the total harmonic distortion. Harmonic Dis-
tortion mode is available when measuring AC current or voltage in Manual select
mode.
The harmonic distortion is expressed as H
n
= (RMS of an individual harmonic n
)/(RMS of the fundamentals) × 100%.
1. Use the navigation buttons to select
and enable Harmonic Distortion
mode.
2. While in Harmonic Distortion mode, use the
and navigation buttons
to navigate through the individual and total harmonic data.
3. When the total harmonic distortion is displayed, the
indicator appears in
the upper part of the display.
4. Press and hold the
button to disable Harmonic Distortion mode.
5.5.3.8 LPF mode
In LPF mode, high-frequency noise is eliminated from the voltage measurement
by a low-pass filter (LPF). LPF mode is intended for measurements on variable-
frequency drives (VFDs). LPF mode is available when measuring AC current or
voltage in Manual select mode.
1. Use the navigation buttons to select
and enable LPF mode.
5.6 Power measurements
5.6.1 Single-phase power measurements
1. Set the function switch to the
position.
2. Insert the black probe lead into the negative COM terminal and the red probe
lead into the positive W terminal.
