Looking to calibrate the evap pressure transducers on a mcquay wdc 050. Can any one help out?

I may be able to help (no promises) I haven't worked on a Mcquay centrif for a while so i may need some prompting.
what controller? Is it Carel with the touch screen and swing out arm? Or older on microtech? (true microtech not re-badged carel)
What sections of the soft ware can you access? I can't remember where the calibration section is but i do have most of the passwords and manuals in boxes in the garage.
Also how far out of calibration is the transducer? If it is a fair way out i would suggest you simply replace it.

Hi Binti. Thanks for the reply. New to this site and to Mcquay chillers. This wdc050 has a swing out display and a micro tech 2. I found that some person put an offset on the evap and cond pressure transducers. I tried putting the password into the swing out display and that allowed me to change the offsets and to calibrate the press transducers. All ok at this time.
