Arithmetic Operators
Test conditions are essentially mathematical equations. The chart below lists
the arithmetical operators used in the QC-5000 software.
Arithmetic operators determine what happens in the test condition. Take a look
at the following test condition to get a better understanding.
In this example, the ‘==’ arithmetic operator determines that Thing_1 must
equal 5mm for the test condition to be true. The entire test condition reads: if
Thing_1 is equal to 5mm. This means the action Measure_Thing_2 will only
be carried out if Thing_1 equals 5mm.
Changing the arithmetic operator changes the entire test condition. For ex-
ample, if the ‘==’ in the example is changed to ‘<=’ Thing_1 must be less than
or equal to 5mm for the test condition to be true.
