Piezo Error corrector


#1

I got some negative Numbers in the L column. I am to be unable to edit the number. I get a message that says the cell is protected. There may be a way to change the number but it’s not obvious.


#2

The number you need to edit is the measurement number that is out of wack (not decreasing from top to bottom) (not the in the Falses column but in the L* column).

Check the instructions on the google sheet under the graph for details.

Got it. Reread the offending sentence little more carefully. In the meantime I just reread the offending patches and the offending minuses went away. Can I assume that when you get a ‘minus’ in the L False column that’s the result of a misread(operator error), and assuming a nozzle check was done prior to cleaning.


#4

Generally the L* falses column are a “False” read made in error from the instrument or placement of the instrument on the target patch, yes.
