Display
 Top display bar indicates:
• Symbol of the tested mode (for example, , , ).
• Frequency of measured signal.
• Memory capacity status bar (only available in certain modes).
• Current date and time.
• Battery charge status.
 Measured RMS values associated with waveforms.
 Values of signals at an instant, t, at the intersection of cursor and the
waveforms. The cursor can be moved along the time scale by pressing the
left/right cursor buttons.
 Measurement selection:
• RMS - True RMS Measurement.
• THD - Total Harmonic Distortion.
• CF - Crest Factor.
• max/min - Maximum and Minimum values.
• Simultaneous display of the various measurements in alphanumeric form.
• Phasor diagram.
 Selection of waveforms to be displayed (use the Up/Down Cursor buttons
to select):
• 3U displays the three phase-to-phase voltages U1-2, U2-3, U3-1.
• 3V displays the three phase-to-neutral voltages V1N, V2N, V3N.
• 3A displays the three phase currents.
• 4A displays the three phase currents and the neutral current.
• L1, L2 or L3 displays the voltage and current, on phase 1, 2 or 3, when
selected.
