Hi All,
I just received an X-Rite 404A color reflection densitometer from my friend (FOC), whom got no idea of what it is.
When I first start using it (pressing it down) on the reflection standard that come with the package, I got no reading on the screen - just blank (Normally, SOME reading should pop up on the screen after several seconds.) When I return the densitometer to the original position, it just pop up the old result. I have tried it on different things, e.g. book, paper, table, etc, and got the same outcome.
I checked the light lamp, when I press the densitometer down, I didn't see any "visible" light come out from the spot, is it normal??? since I didn't get any error message from the densitometer (e.g. Lamp fail).
or do I need to re-calibrate or do something else?
Thanks
Jack
