| The QC field values are a bit packed representation of true/false values for the tests that may have been performed. A QC value of zero means that none of the tests performed on the value failed.
| 
| The QC field values make use of the internal binary format to store the results of the individual QC tests. This allows the representation of multiple QC states in a single value. If the test associated with a particular bit fails the bit is turned on. Turning on the bit equates to adding the integer value of the failed test to the current value of the field. The QC field's value can be interpreted by applying bit logic using bitwise operators, or by examining the QC value's integer representation. A QC field's integer representation is the sum of the individual integer values of the failed tests. The bit and integer equivalents for the first 5 bits are listed below:
| 
| bit_1 = 00000001 = 0x01 = 2^0 = 1
| bit_2 = 00000010 = 0x02 = 2^1 = 2

| bit_4 = 00001000 = 0x08 = 2^3 = 8
