SECTION 3. PREPARATIONS FOR GAS SAMPLING AND MEASURING
3-1. Connect the sampling tube to the gas inlet “GAS IN” on the panel and apply the sampling gas
(SFG) from the sampling point. The sampling gas pressure should then be less than 0.7 MPa.
3-2. Make sure that the pressure regulator on the panel is set 0.1±0.02MPa. Regulator adjustment
must be done at step 4.
SECTION 4. START MEASURING
4-1.Turn the change over cock (measuring gas/air) vertical. The unit will begin to measure. Adjust
the flow rate so that it is more than 0.4 L/min at flow meter “A” (left side n the panel).
