Difference between 設定する and 調整する


Sorry, I don't have any example sentences...  
Anyway, usually I heard the word 設定{せってい} in the meaning of "adjusting
something". But now, in the factory, I have come across the phrase
"圧力{あつりょく}を調整{ちょうせい}する".  
Could you please define the difference in usage between 設定{せってい}する and
調整{ちょうせい}する?




I think the difference can be summarised as:

  * 設定 - to set or configure 

  * 調整 - to set or configure **towards a desired/expected outcome or value**

I think 設定 is to set it up so that it works, while 調整 has a goal in mind.

Looking up some online dictionaries:

[調整](https://kotobank.jp/word/%E8%AA%BF%E6%95%B4-568677#E5.A4.A7.E8.BE.9E.E6.9E.97.20.E7.AC.AC.E4.B8.89.E7.89.88):

> (大辞林 第三版)  
>  1. 調子の悪いものに手を加えてととのえること  
>  2. ある基準に合わせてととのえること。過不足なくすること。

設定 means to set up or establish according to some standard/condition that was
decided.

調整 means to adjust it from a undesirable or bad state, back in order to a
desired state. Or in the second explanation, to adjust something away from
being too much or too little in order to conform with an established standard.




設定 often implies you start from _tabula rasa_.

調整 is more like optimization.
