help using pocket pro plus

[Fat_Bastard]

I guess I am stupid,I bought a pocket pro plus from hach.I have downloaded the pdf file for instructions and find I cannot calibrate the unit or reliabley find all the functions and navigate through them.the interface seams very clunky to me.
can some oine please explain to me how to work this unit?

You have DOC022.53.80394?

About all I could do would be to repeat what it says in that pdf. It's pretty straight forward IMO. I can't say it any better. Perhaps you are totally unfamiliar with pH and its measurement. https://www.homebrewtalk.com/f128/ph-meter-calibration-302256/ might help.
