The Meter screen gives an overview of voltages and currents in all phases. Also
frequency and Crest Factors are shown. The Crest Factor CF indicates the amount of
distortion: a CF of 1.41 means no distortion and higher than 1.8 means high distortion.
Use this screen to get a first impression of power system performance before examining
the system in detail with other measuring modes. The number of columns in the Meter
screen depends on the power system configuration.
The figures in the Meter screen are present values that may update constantly. Changes in
these values over time are recorded as soon as the measurement is turned on. The
recording is visible in the Trend screen.
