      Sherry LynnAug 14, 2025
      If the AVL Test Equipment leak test fails, you should: * Check the entire sampling line for leaks, from the probe tip to the inlet on the rear panel. * Disconnect the probe hose and connect a leak-proof 2 m hose. * Inspect the O-rings in the filter housing and condensate trap, and check the connections for leaks on the probe hose and condensate drainage hose. * Also, check if the tester was stored with condensate at temperatures below 0° C.
