5.1.5 PGE11 short and medium Function check
For the Function test of the PGE11 short and medium use the PGE11 Gas Test kit as described
in the procedure below. The Function test is not taking into account variations in ambient
pressure, wind or other factors so it is not expected to precisely verify the accuracy of the
detector. For better accuracy the detector shall have been powered on in fresh air for more
than 20 minutes, ambient should be around room temperature, no wind and deviations in
ambient pressure from the ideally 1013 mBar should be accounted for in the gas
measurement. This is explained in chapter 5.2 Perform a check of the Gas Detector accuracy.
Requirements:
● PGE11 Gas Test kit. Be aware that the correct type of kit is selected
○ PGE11 short Gas Test kit
○ PGE11 medium Gas Test kit
● Gas cylinder with same type of gas as Detector is rated to detect
○ Concentration of test gas recommended to 50 ±10 %FS
○ Flow rate between 1 and 10 liter/min.
● Flexible gas hose to connect between gas cylinder and Gas Test kit
Procedure:
1. Connect the tube from the Gas cylinder to the gas nozzle of the PGE11 Gas Test kit.
2. Attached the PGE11 Gas Test kit to the PGE11 as shown below.
3. Apply the gas with a flow between 1 and 10 liter/min
4. Observe that the detector indicator is showing gas alarm or that the expected gas
response is received at the control system
5. With a response of the test gas concentration ±10 %FS, the Gas Detector has passed
the test
