How to Test the Performance of Your Analyzer
There are two different ways to verify the performance of your analyzer. One method meets
ANSI/NCSL Z540–1–1994 standards, and the other method does not. To determine which
type of verification you wish to perform, refer to the following descriptions and flow charts.
ANSI/NCSL Z540–1–1994 Verification
This type of verification consists of conducting the preliminary checks, system verification,
and the performance tests without stopping to troubleshoot. Exceptions will only be made
in case of catastrophic failure or cable connector damage. In order to obtain data of how the
analyzer was performing at the time of verification, these tests must be done even if you
are aware that the analyzer will not pass. Obtaining the data (system verification printout
and performance test record) at this point is necessary so that you will understand that
your measurements may not have been accurate. You must wait until after the
ANSI/NCSL Z540–1–1994 verification is complete before troubleshooting and repairing
any problems. After troubleshooting, consult Table 14-1 on page 14-35 to find the
necessary adjustment procedures. Then repeat the system verification and performance
tests, generating a new set of data.
Non-ANSI/NCSL Z540–1–1994 Verification
This type of verification consists of conducting the preliminary checks, system verification,
and performance tests, but stopping at any point if the analyzer fails a test. You will
troubleshoot and repair the first problem encountered without continuing to other tests.
After troubleshooting, consult Table 14-1 on page 14-35 to find the necessary adjustment
procedures. Then repeat the system verification and performance tests. As the analyzer
passes the system verification and all the tests, you will print out the system verification
results and fill in the performance test record.
