7.6.5 Sequence with External AC Power Source
The SEQUENCE tool can also be used with an external AC power source. To do so the option “use
external AC source” in the settings folder must be activated.
When active, and after clicking the “start sequence” button, the “Catch Value” window guides the user
over the necessary voltages to complete the sequence.
The descriptions of the elements in the “Catch Value” window are:
Bar Finding Voltage
If the blue needle is inside the pink colour area, the applied
voltage is too low. You have to increase the voltage.
If the needle is inside the red colour area, the applied voltage is
too high. You have to decrease the voltage.
If the needle is inside the green colour area, the voltage is close
enough to the expected value (e.g. 3.00kV). The window will be
automatically closed after reaching the required accuracy and
the values will be recorded. After that the sequence will execute
the next cell in the spreadsheet SEQUENCE.
The actual measured voltage will be shown at the left or right
hand side of the needle.
Button Apply
Pressing this button will close the window and the actual
measuring values will be recorded.
The next cell of the spreadsheet SEQUENCE will be executed.
Therefore you can continue the sequence without reaching the
actual voltage step.
Label Action
This message is used to show you how you should control the
voltage of the external AC Power Source.
Button Additional Settings
Pressing this button will scale up/down the dialog.
Additional fields for defining the green area are getting
visible/invisible.
Input Min. Level of set Voltage
In this field the lower value of the green area can be defined in
percent [%] of the applied voltage.
Input Max. Level of set Voltage
In this field the higher value of the green area can be defined in
percent [%] of the applied voltage.
Input Level of Label "Slow"
This field is used to set the level of voltage when the message
"Slow Up" and "Slow Down" appears. It is relative to "set
voltage".
