Most manufacturers strongly recommend verifying the calibration of their confined space instruments with a known concentration test gas before use.  This test is very simple and takes only a minute or so to accomplish.  Most manufacturers agree that it is not necessary to make a calibration adjustment unless reading are off by more than some percentage of the expected value.  while advice may differ between manufacturers, several suggest using ±10% as the criterion for determining whether adjustment is required.

Calibration checks can be done in a tiered approach:

  1. Bump Test
    The meter is shown some gas source and it shows some response and may alarm. The gas may be a calibration gas or an indefinite source such as a butane lighter or magic maker.
  2. Calibration Check
    The meter is shown calibration gas and the user verifies that the readings are within a predefined amount, typically ±15% of the calibration gas concentration.
  3. Full Calibration
  4. The meter is shown calibration gas and readings are adjusted (automatically or manually) to the certified gas concentration.
  5. Factory Calibration
    The meter is returned to a factory-certified service center for testing and adjustment.
