currents and frequency etc. The Scope waveform screen offers an oscilloscope style
of display of voltage and current waveforms with a fast update rate. The screen
header shows the related rms voltage/current values. Channel A (L1) is the reference
channel, starting at 0V are displayed.
Available function keys:
F1 Selection of waveform set to be displayed: V displays all voltages; A
displays all currents. A (L1), B (L2), C (L3), N (neutral) give
simultaneous display of phase voltage and current for the selected
phase.
F3 Access to cursor, when the Cursor is on, the waveform values at the
Cursor are displayed in the screen header.
F4 Selection of Zoom function and Cursor move function. When the Cursor
is selected, press left/right arrow keys to move the cursor; when the
Zoom function is selected, press direction keys to expand or shrink
waveforms.
F5 Switch between HOLD and RUN
7.2 Voltage/Current/Frequency
This function is used for measuring steady voltage, current, frequency and crest
factors. 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.
7.3. Table screen
The number of columns in the Table screen depends on the power system
configuration. The figures in the Table 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.
