    3 Maintenance 3.1 Periodic Maintenance It is essential that the test and calibration schedule be adhered to. Honeywell Analytics recommends the following maintenance schedule: • Response test prior to each use. Expose sensor to a sample of the target gas to verify proper sensor response and alarm functions.
