7.2.1 Calibration
Calibration must be performed using a flow regulator with a flow rate set to 0.25 liters per minute.
Calibrate at room temperature. Allow detector(s) to stabilize for 30 minutes before calibration. Stated
calibration performance is for room temperature.
Equipment
For Part Numbers, see section 13.1 "Detector Spare Parts and Accessories".
• Calibration Check Gas Cylinder
• 0.25 liters/min. Flow Regulator
• 1/8" ID Superthane Ester Tubing
• Calibration Cap
(13) Install SunShield on detector.
Under normal circumstances MSA recommends calibration before each deployment.
Please check your national legislation.
The calibration procedure adjusts the zero and span values for any sensor that passes the cali-
bration test; sensors that fail calibration are left unchanged. Since residual gas may be present,
the detector may briefly go into alarm after the calibration sequence is completed.
