Section 3-455/A2/B2
PERFORMANCE CHECK
This procedure allows the basic performance specifications to be checked without removing the instrument covers. It is in
tended for use in incoming inspection to determine acceptability of newly purchased or recently recalibrated instruments.
OPTIONS
TEST EQUIPMENT REQUIRED
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 of the
455/A2/B2. Specifications given for the equipment are the
minimum necessary for accurate results.
