How to Find Hours on Heads?

I'm looking at used PV GS320, 250 or 400. I've read that there is a function in the menus for reading the total hours on the heads. I never owned one so I am clueless to tell sellers how to check the hours. What's the procedure? Is it the same on these three models? -- Matt

Thanks Poncho. Now i just have two problems. 1) Most individual sellers will be unable to do what needs to be done to read the hours. 2) My own mathematical ignorance prevents me from understanding the hex to decimal conversion. This is something that I will rectify ASAP. Th first problem may be insoluble though. -- Matt

Hehehe.... hex..... Read through the threads I added. They show you how to use the Microsoft calculator which windows has and there are a few examples.
