4 Preparing the Stabil-Ion System for
Operation
4.1 Preparing for Pressure Measurement with the Stabil-Ion Gauge 1
1. The steps in this Section (4.1) assume:
a. Your Stabil-Ion System has been properly set up and installed per the instructions in
Chapters 2 and 3.
b. The gas in your vacuum system is air or N 2 . For other gases you must follow the
instructions in Section 4.1.3 on page 4-5 for using Stabil-Ion Gauges and in Section 4.6.1
on page 4-12 for using Convectron Gauges.
c. That you are reasonably familiar with the general theory of operation of hot cathode
ionization gauges and thermal conductivity gauges.
We recommend you consult a good text book if you are unfamiliar with vacuum technology or
require more information on the general theory of operation of an ionization gauge or thermal
conductivity gauge. Extremely useful information is provided in the following references.

2. Turn on the Stabil-Ion System by pressing the Control Unit power switch labeled ON. See
Figure 4-1.
3. Convectron Gauge equivalent N 2 pressures will be displayed whenever power is applied if the
gauges and cables are installed. Make sure the IG1 AUTO and IG2 AUTO switches are in the
IG AUTO ON or OFF position and have not been left in the set positions. See Section 4.6 on
page 4-11 for information on Convectron Gauge pressure measurement.
4. Open the front door of the Control Unit and make the following settings on the electrometer
module for each Stabil-Ion Gauge channel.
1. For completeness, all available capabilities are assumed present. Not all capabilities may be present in the
product you have specified.
