indicates the percentage of represented parameter. Related parameter value will be shown in the screen
header when moving cursor to specified bar.
For instance power quality monitoring bar graph screen contains: Voltage RMS, harmonics, flicker, rapid
voltage change, dips, swells, interruption, unbalance and frequency. The related bar length will increase
if a parameter exceeds its nominal value. The below figure explains this:
