Real-time Data
(cont.)
• Text Display Meters - Meter mode also functions as a true rms
voltmeter, a true rms ammeter, and a watt meter. Voltage,
current, power measurements, along with hundreds of other
calculated and advanced power and power quality parameters,
are displayed on the meter screens in textual/tabular format.
• Scope Mode - Scope mode functions as an oscilloscope,
displaying real-time waveforms of voltage and current for up to
eight channels simultaneously, updated at approximately once
every three seconds. The colors of waveform display are user
programmable. Scope mode also provides a textual display of
rms values, division for axis values, and frequency.
• Dashboard - Dashboard presents a visual way of seeing present
values as well as if any events occurred, such as out-of-limit
conditions, for each of the displayed parameter. The dashboard
displays status summary for Power Quality, Energy/Demand,
and Motor Quality parameters. It displays meter data (or event
count) in a 2x3, 3x4, or 4x6 matrix. It is also color coded to
indicate whether or not the parameter is within limits.
• Phasor Diagram - The phasor screen displays a graph that
indicates phase and magnitude relations between voltage and
current based upon the angles at the fundamental frequency, as
determined by Fourier analysis. Phasor diagram displays voltage
and current phasors for all channels.
Functioning as a phase angle meter, the unit can display system
imbalance conditions and provides such information in textual
form also. The phase angle display can also verify if monitoring
connections have been made correctly. Animated phasor demo
rotations demonstrating resistive, inductive and capacitive loads
can be displayed.
• Harmonics - Harmonics and interharmonics display the
amplitude and phase of each harmonic to the 127th harmonic in
both graphical and textual format.
