Phase Colors

Measuring results belonging to different phases are presented with individual colors. If -
for a certain phase - voltage and current are displayed simultaneously, the voltage color
has a dark tone and the current has a light tone. The set of phase colors can be chosen via
the SETUP key and function key F4 – USER PREF. For detailed information see Chapter
20.

Screen Types

Below you will find a brief description of each screen type and its purpose. The
measuring mode it is used for is given as well as the manual chapter with detailed
information. Bear in mind that the amount of screen information depends on the number
of phases and the wiring configuration. Refer to Figure 5-1, item 1 ... 5.
5-2
Meter screen: gives an instantaneous overview of a big number of
1
important numerical measuring values. Used for: Volts/Amps/Hertz
(Chapter 8), Dips & Swells (Chapter 9), Harmonics (Chapter 10),
Power & Energy (Chapter 11), Flicker (Chapter 12), Unbalance
(Chapter 13), and Power Quality Monitoring (Chapter 18).
Trend screen: this type of screen is related to a Meter screen. Trend
2
shows the course over time of measuring values from the Meter screen.
After selection of a measuring mode, the Analyzer starts recording all
readings in the Meter screen. Used for: Volts/Amps/Hertz (Chapter 8),
Dips & Swells (Chapter 9), Power & Energy (Chapter 11), Flicker
(Chapter 12), and Inrush Currents (Chapter 15).
Waveform screen: shows voltage and current waveforms as displayed
3
on an oscilloscope. Channel A (L1) is reference channel and 2 complete
cycles starting at 0 volt are displayed. The nominal voltage and
frequency determine the measuring grid size. Used for: Scope
Waveform (Chapter 7) and Transients (Chapter 14).
Phasor screen: shows the phase relation between voltages and currents
4
in a vector diagram. The vector of reference channel A (L1) points to
the positive horizontal direction. The A (L1) amplitude is also reference
for the measuring grid size. Used for: Scope Phasor (Chapter 7) and
Unbalance (Chapter 13).
Bar Graph screen: shows the density of each measuring parameter as a
5
percentage by means of a Bar Graph. Used for: Harmonics (Chapter 10)
and Power Quality Monitor (Chapter 18).
