Page 18: Initial Gas Testing
FGD10A Oxygen / Toxic Gas Detector Initial Gas Testing FGD10A units are factory calibrated as detailed on the calibration certificate supplied with the instrument. However, it is always advisable after installation to confirm that the instrument reads zero with no gas present and responds accurately when presented with an appropriate concentration of the target gas. - Page 19 STATUS SCIENTIFIC CONTROLS Installation, Commissioning & Routine Gas Testing FGD10A Oxygen / Toxic Gas Detector Figure 6 – Arrangement for Application of a Certified Test Gas Without weatherguard With weatherguard Calibration Metal sampling adaptor, Stock No. SS336 Adaptor 6mm O.D.
