Initial Startup
Vacuum Test
With the 1/8" Valco cap on the black PFA transfer line still in place and the air
supply to the ozone generator off, set the internal air regulator to 0 psi (fully
counterclockwise), and power on the SCD or NCD by plugging the power cord
into the house power supply. The SCD and NCD will power up in STANDBY
mode, with the pump and the ozone generator OFF. For this test, the desired
mode is power ON, vacuum pump ON, ozone generator OFF, display range in
the low sensitivity mode and PRESSURE signal displayed. Press the following
controls in the order shown in order to start the vacuum pump and to view the
reaction cell pressure.
After the pressure has stabilized (
~
5 minutes), record the pressure below.
Typical pressure in the reaction cell should be 1-2 torr with the oil-sealed
pump, or 5-8 torr for the oil-free pump.
