8.2. Level 1 Calibrations versus Level 2 Checks
Essential to quality assurance are scheduled checks for verifying the operational status of
the monitoring system. The operator should visit the site at least once each week. It is
recommended Level 1 zero and span check conducted on the analyzer every two weeks.
Level 2 zero and span checks should be conducted at a frequency desired by the user.
Definitions of these terms are given in Table 8-4.
