The “+” or “–” sign is indicated when the positive or

negative value has been measured or calculated. Each

segment represents 2500 or 500 counts depending on the

range indicated on the peak bar graph. See the table below.

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 to

access the Frequency measurement mode for current or

voltage measurements — voltage or current on secondary

display and frequency on primary display. Alternatively,

pulse width (ms) or duty cycle (%) can appear on the
