Setting the Gas Supply Pressure
Set the Gas Supply Pressure as follows:
1.
Set the Carrier Gas cylinder or main line supply regulator pressure to 35 psi.
2.
Set the pressure on the Carrier Gas regulator-tee so that the gauge reads 29 psi.
Caution:
The maximum Carrier Gas pressure to the instrument must not exceed 32 psi. Input
pressures greater than 32 psi (2.2 Bar) will damage the system.
Note: When using compressed gas cylinders, the tank must be replaced when the pressure falls below 300 psi (on
the first stage of the regulator).
