Starting blow back from the display

[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

blinking.
4) To abort blow back, you can touch the Reject key to skip the blow back time and enter the hold

Reject key, then hold time is skipped and you revert to measurement mode.
