CHAPTER 4 TESTING
4.2 AV AND AS MODELS STRAIN GAUGE PERFORMANCE TESTS
The following performance tests are used to evaluate the balance operation before and after repairs.
Each balance tested must meet the requirements specified in each test as well as the specifications
listed in Table 1-2 and Tables 4-1and 4-2. Tolerance values are expressed in counts. A balance which
passes each of these three tests meets the manufacturing specifications.
