PERFORMANCE CHECK
This procedure allows the basic performance specifications to be checked w ith o u t removing the instrument covers. It is in­
tended fo r use in incoming inspection to determine acceptability o f newly purchased or recently recalibrated instruments.
OPTIONS
TEST EQ U IPM EN T R E Q U IR ED
Your instrument may contain options (such as Option 5 or
Option 7) that can alter this procedure slightly. If this is
the case, refer to the Options section(s) in this manual and
perform the necessary performance checks.
The test equipment listed in Table 3-1, or equivalent, is re­
quired to perform a complete Performance Check o f the
455/A2/B2. Specifications given fo r the equipment are the
minimum necessary for accurate results.
