Semi-auto blow back can be started from the display or by an external contact input.
<Procedure>
Starting blow back from the display
1) On the basic panel display, touch the Setup key to display the [Execution/Setup] display. Select
[Blow back]. Next select [Start blow back] and touch the Enter key. Blow back is performed
starting from Channel 1.
2) If a display like Figure 10.27 appears, then mode is set to [No function]. Refer to Subsection

3) During blow back a display like Figure 10.28 is displayed, with the affected channel number
blinking.
4) To abort blow back, you can touch the Reject key to skip the blow back time and enter the hold
time. If you touch the Enter key here, then blow back for the next channel starts; if you touch the
Reject key, then hold time is skipped and you revert to measurement mode.
