:
Measure Isec
Decim(x): 1
From this window you can define the settings of the chart, the graphics area is activated by
scrolling with the DX arrow on the next screen.
The measured value can be chosen from:
Isec
performance of the secondary current (measured by
Rogowski, if available, or primary sensor)
Vdc
Internal DC link voltage performance
D%
IGBT open rate performance
Vpri
Modulated primary voltage performance
Ipri
Primary current performance
Vsec*
Secondary voltage performance
Pot*
Power output performance
Res* Resistance
performance
* only if secondary voltage reading is enabled VE=yes
The value of decimation Decim (x) indicates the horizontal scale (time) range and is equal
to the number of points where the system will display the average for a single pixel.
The system automatically acquires a new screen with a trigger on the first warm weather of
each point, or, in the case of Seam, each time a set-point.
After a new approach is necessary to initiate a new point to refresh the screen graphication.
The graphics window is automatically scaling according to the values obtained. It 'be careful
when comparing the graphs together, the possibility that the screen has been scaled
vertically so different between the two acquisitions. It will be possible to read the graph:
•
the unit of time, displayed as ms / div, which is derived from the frequency of the
system and the decimation value chosen;
•
the unit of value shown (KA, V,%, etc..), Scaled so as to ensure a meaningful display
the acquired waveform. The full scale value displayed in the graph represents the
maximum allowed in this moment for the y-axis
