QUESTION
How is precision set in the QCC files and if I change the precision on my inspection machine (CMM), will it change in QC-CALC?

ANSWER
The answer is generally No. The reason is that most machines do not send the precision to QC-CALC. Since most don't, QC-CALC ignores the one or two that do; this allows for better consistency.

Most machines send 7 decimal places which are all stored by QC-CALC. The precision that is set only affects the viewing of the data.

Precision is set generally in the File Creation Defaults. This is found in Tools > Options > File Creation Defaults > Format Settings in QC-CALC Real-Time or QC-CALC SPC. The value you set there is defaulted when new QCC files are created.

Since Precision is set at the Feature Level, you are free to override this value for any feature in your QCC file. It will not be overwritten when you collect more data. The fastest way to edit this type of information is under Edit > Nominals and Tolerances in QC-CALC SPC as you can change multiple features simultaneously.
