The frequency measurement function is able to detect the
presence of harmonic currents in neutral conductors and
determine whether these neutral currents are the result of
unbalanced phases or non- linear loads.
• Press
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 be
displayed on the primary display by pressing
This allows simultaneous monitoring of real- time voltage
or current with frequency, duty cycle, or pulse width.
• Hold
current reading on the primary display.
