How accurate is vivaldi II pressure guage?

Post by UFGators »

I have a vivaldi II that was calibrated by Chris' coffee. Without having to splurge and buy a portafilter guage to check the accuracy of the machine brew guage, does the guage read true to real pressure when brewing or does it read high or low? I am thinking about tweaking the pressure guage slightly bellow 9 bars to make a more forgiving shot. I would appreciate the help.

I just checked mine with a p/f pressure gauge & it was spot on.

mine was pretty spot on too. not 100%, maybe 92%
then again, it wasnt hard getting my own made up from a plumbing supplies store
