Hello Shuhei, another solution is to use the signal intensity instead of percentage for pressure adjustment (always using this approach, never get into trouble) For doing this, click on the menu (small round button on top of the dual inlet panel) to fix the signal intensity you want on the left or right side (your bellows need to be calibrated first). For adjusting the opposite side, you can do before runs like the first one or in the method there is a section that describes how the slave bellow should be adjusted. In each case, ISODAT ask you how close the signal should be. Usually, 100 mV difference allowed did not create any zero enrichment issue and adjustment is pretty fast. Hope this will help.
