The frequency measurement feature helps to detect the
presence of harmonic currents in neutral conductors and
determines whether these neutral currents are the result of
unbalanced phases or non- linear loads. Press
the frequency measurement mode for current or voltage
measurements — voltage or current on the secondary display
and frequency on the primary display. Alternatively, pulse
width (ms) or duty cycle (%) can appear on the primary
display by pressing
simultaneous monitoring of real- time voltage and current
with frequency, duty cycle, or pulse width. Voltage or
current resumes on primary display after you press and hold
for more than 1 second.
