Calibration Frequency Recommendation
2. If these tests demonstrate that it is not necessary to make a full calibration
(adjustment) the time between checks may be lengthened. The interval
between calibration checks should not exceed 30 days.
3. When the interval has been extended the toxic and combustible gas
sensors should be replaced upon warranty expiration. This will minimize the
risk of failure during the interval between calibration checks.
4. The history of the instrument response between checks should be kept.
Any conditions, incidents, experiences, or exposure to contaminants that
might have an adverse effect on the calibration state of the sensors should
trigger the need for an immediate calibration check before further use.
5. Any changes in the environment in which the instrument is being used, or
changes in the work which is being performed, should trigger a resumption
of daily calibration checks.
6. If there is any doubt at any time as to the accuracy of the sensors, perform
a calibration check, before further use.
Gas detectors used for the detection of oxygen deficiency, flammable gases
and vapors, or toxic contaminants must be maintained and operated properly
to do the job they were designed to do. Always follow the guidelines provided
by the manufacturer for any gas detection equipment you use!
If there is any doubt regarding your gas detector's accuracy, do a calibration
check! All it takes is a few moments to verify whether or not your detectors
are safe to use.
One Button Automatic Full Calibration and Calibration Docks
While it is only necessary to do a calibration check to ensure that the
sensors are working properly, all current Honeywell Analytics/Sperian, and
/Honeywell Analytics Safety Systems gas detectors offer a one button auto
full calibration feature. This feature allows you to do a full calibration of a gas
48
detector in about the same time as it takes to complete a calibration check.
The use of calibration docks can further simplify the tasks, while automatically
maintaining electronic records of sensor performance.

gas mixtures". This note provides procedures to ensure safe calibration of
LEL sensors that are subject to poisoning.
