Tiered approach to Calibration Gas Checks
Most manufacturers strongly recommend verifying the calibration of their confined space instruments with a known concentration test gas before use. This is known as a calibration gas and, while the test is very important, it is also simple and takes only a minute or two to accomplish.
Most manufacturers agree that it is not necessary to make any calibration adjustments unless calibration gas readings are off by more than some percentage of the expected value. While advice may differ between manufacturers, most suggest using ±10% as the criterion for determining whether adjustments are required.
Calibration gas checks can be done in a tiered approach:
Bump Test: The meter is shown a gas source, 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.
Calibration Check: The meter is shown calibration gas and the user verifies that the readings are within a predefined amount, typically ±10% of the calibration gas concentration.
Full Calibration: The meter is shown calibration gas and readings are adjusted (automatically or manually) to the certified gas concentration.
Factory Calibration: The meter is then returned to a factory-certified service center for testing and adjustment.
