Note:
Depending on the mA Operation Mode that is selected, if gas leak is present, the detector will indicate a gas leak SPL reading.
Note:
If the output reverts to 3 mA or < 1 mA, a Warning or Fault is present. Follow the instructions below to investigate and clear a Warning or
Fault (see Clear Faults or Warnings).
If local regulations or site practices require that a gas leak test is done to check that the detector is functioning, refer to the Maintenance
section of this manual for more instructions.
