Operation
1) When not using the Portable N

O Source, keep the on/off valve closed (knob
turned completely clockwise).
2) To use the Portable N
2
O Source, check that there is tubing connecting the
source to the instrument and then open the on/off valve by turning the knob
completely counter-clockwise. Use only moderate hand force to loosen the
knob (do not force with tools).
3) The pressure gauge will read ~600 psi, until the liquid N

O in the cartridge is
exhausted. Then the pressure will rapidly fall off.
4) To stop using the N
2
O source, close the on/off valve by turning the knob
completely clockwise. Do not tighten the knob more than hand-tight.
