4.21 ) the second pressure alarm function settings (SEL2)
In working state, press the "SET" once ,
” PV” shows “ SV ” , then loosen the button .
Press
“ SET “ again for 5 seconds , it will enter into output amplitude high limited value setting , “ PV
“ shows “ OL-U “, then loosen the button .
Then Press
“ SET “ seven times , enter into the second pressure alarm function settings ,” PV “ shows
“ SEL2” .
Pressure "
