To Verify That the NPD Bead Is Ignited
To verify that the bead is ignited, look through the vent hole
on the detector lid to see if the bead is glowing orange.
The NPD output is selected by the operator as part of the
adjust offset process and generally is between 5.0 and 50.0
pA.
WARNING
Hot exhaust! Detector exhaust is hot and can cause burns.
