A sudden inrush of N
2
into the pressurization circuit may result in damage
to internal parts. Close the pressure regulator by turning the knob counter-
clockwise before pressurizing the circuit.
The N
2
flowrate can be
adjusted with the pressure
regulator according to the
process (see
A 40
).
A mass flowmeter, located
behind the front panel, allows
flow reading on the hand-held
remote module.
