Since you have a Quik Link, remove the chain and measure a 3' section. (3X better resolution than measuring 12")
Use that as a reference to calibrate your chain checker.
On my CC, I know if it reads .5% that it's actually still good.
IF it reads .75%, THEN I'll grab the tape measure. I just haven't gotten to that point yet.
So, your CC can be useful for a quick check to prove the chain is good.
To prove it's bad can take a bit more research for your specific CC.
