missing LAB values in 51-step target scan

Piezography Professional Tools

I scanned the 51-step target but when I read the LAB values there were numbers in the “L” column but the “A” and “B” columns contained all zeroes - any ideas where my mistake was?

Not sure where your mistake is but it will still work just fine. All that is required in values in the L* column.
