Frequency Test Mode
Never measure the frequency where the voltage or current level exceeds the

specified range. Manually set the voltage or current range if you want to
measure frequencies below 20 Hz.
Measuring the frequency of a signal helps 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.
Your multimeter allows simultaneous monitoring of real- time voltage or current
with frequency, duty cycle, or pulse width measurements.
