5 Operation of a Stabil-Ion System
The instructions in this chapter assume the instructions for Setup, Installation, and Preparing For
Operation have been completed. See Chapters 2, 3, and 4.
1. Press the Power switch on the Control
Unit to ON (see Figure 5-1).
2. Convectron Gauge pressures will be
displayed on lines A and B of the
display whenever the power switch is
ON. A “–” sign will be displayed if the
Convectron gauge is unplugged.
During a fast pumpdown from atmosphere, thermal effects will prevent the Convectron Gauge
from tracking pressure accurately below 10
-3
Torr. After about 15 minutes, indications in the
10
-4
range will be valid and response will be rapid. Zero adjustment at vacuum may be
performed at this time (or sooner if readings in the 10
-4
range are not needed).
