Product Features Chapter 1
 Enter button and four buttons that enable movement of the cursor,
browsing or the selection of data.
 Buttons for directly accessing the six display modes at any time:
• Transients (set recording or view recorded transient):
– Displays waveforms such as, motor startup current (INRUSH) and
interruptions.
• Harmonics View:
– Display of the harmonic ratios of voltage, current and power, for each
harmonic through the 50th.
– Determination of harmonic current produced by non-linear loads.
– Analysis of the problems caused by harmonics according to their order
(for example, heating of neutrals, conductors, motors).
• Waveforms View:
– Displays voltage and current waveforms or vector representation
(Phasor diagram).
– Identification of signal distortion signatures.
– Display of amplitude and phase unbalance for voltage and current.
– Checking connections for correct phase order.
• Power / Energy (view or start energy monitoring):
– Display of power levels and the associated parameters (power factor,
displacement and tangent).
– Energy monitoring.
– Four quadrant measurement to discern produced/consumed active
energies and inductive/capacitive reactive energies.
• Recording (set recording or view recorded data):
– Time-related representation as bar charts or curves, of average power
levels or of the average value of any parameter.
– Line voltage stability check.
– Management of power consumed and generated.
– Monitoring of harmonic variations.
• Alarm:
– Provides a list of the alarms recorded according to the thresholds
programmed during configuration.
– Logging of interruption with half-cycle resolution.
– Determination of exceeding energy consumption.
