Measurement results in Q parameters
The TNC saves the measurement results of the respective touch 
probe cycle in the globally effective Q parameters Q150 to Q160. 
Deviations from the nominal value are saved in the parameters Q161 
to Q166. Note the table of result parameters that are listed with every 
cycle description.
During cycle definition the TNC also shows the result parameters for 
the respective cycle in a help graphic (see figure at upper right). The 
highlighted result parameter belongs to that input parameter.
Classification of results
For some cycles you can inquire the status of measuring results 
through the globally effective Q parameters Q180 to Q182: 
The TNC sets the rework or scrap marker as soon as one of the 
measuring values falls outside of tolerance. To determine which of the 
measuring results lies outside of tolerance, check the measuring log, 
or compare the respective measuring results (Q150 to Q160) with 
their limit values.
In Cycle 427 the TNC assumes that you are measuring an outside 
dimension (stud). However, you can correct the status of the 
measurement by entering the correct maximum and minimum 
dimension together with the probing direction.
Class of results
Parameter value
Measurement results are within tolerance
Q180 = 1
Rework is required
Q181 = 1
Scrap
Q182 = 1
The TNC also sets the status markers if you have not 
defined any tolerance values or maximum/minimum 
dimensions.
