e. Place the flowmeter tubing over the male hose adapter of the measuring tool to begin
measuring flows. See
Figure 263. NPD Gases Measuring Tool (2)
14. Measure the gas flow rate.
a. Open the GC user interface.
b. Turn the Hydrogen flow On.
i. Measure the gas flow and verify that the actual flow rate corresponds to the
setpoint value.
c. Turn the hydrogen flow Off.
d. Turn the Air supply On.
i. Measure the gas flow and verify that the actual flow rate corresponds to the
setpoint value.
e. Turn the Air flow Off.
f. Turn the Makeup gas flow On.
i. Measure the gas flow and verify that the actual flow rate corresponds to the
setpoint value.
g. Turn the Makeup Off.
15. Remove the flowmeter adapter measuring tool from the detector body proceeding in the
reverse order in which it was installed.
a. Using forceps or tweezers, reinstall the insulator into the detector body.
16. Reinstall the insulator and the collecting electrode.
a. Using forceps or tweezers, reinstall the insulator into the detector body.
