Page 20: Test Procedure
5.5. The final stage of the installation consists in a final check of the WG.EG operation: 5.5.1. Ensure that the detector is properly powered for at least 15 minutes. During this time, when the power is supplied, the sensor of the detector may show much lower sensitivity and its metrological performance is limited. - Page 21 – frequency 2.5 Hz (the indicator state changes every 0.2 s); fast For the other WG.EG detector models [i.e. WG-11 (14, 15, 73, 8R8, 28, 0E/N2O).EG...], the possibility of activating the sensor test mode is disabled – it is unnecessary due to the lack of procedures for averaging the concentration measurement result over time.
