Test Equipment
The performance verification procedures use external traceable test equipment to
directly check warranted characteristics. If you substitute equipment, always
choose instruments that meet or exceed the minimum requirements specified in
Table 6.
Alternative test equipment must meet or exceed the intended minimum
requirements. If you substitute equipment, you may need to modify the
performance verification procedures.
NOTE. Before beginning the performance verification procedures, warm up the
test equipment according to the manufacturer’s recommendations.
