P a g e
Check the calibration gas concentrations, cylinder expiration date, and the monitor gas settings and re-test the unit.
If everything looks correct and the unit fails, perform a Zero calibration followed by a Span calibration. Do not use
the monitor until the reason for the discrepancy for the test has been determined and corrected.
WARNING
If the Bump Test fails, do not use the monitor until a successful Bump Test or Calibration
is performed.
