4.3.3.4 Selecting Gas Type for the Stabil-Ion Gauge
The Stabil-Ion Gauge comes with a Memory Module containing calibration data for nitrogen. These
data are loaded into the Controller memory as gas “
a ” during the Memory Module loading
procedure. See Section 4.3 on page 4-2. If a Memory Module is purchased and installed for a
second gas “
b ”, gas selection may be done using the following process:
Note: If the Stabil-Ion Gauge calibration is for a gas type other than N
2
(or air), we suggest placing a
label on the slip-in gas card display line indicating the gas type or types used for calibration to
prevent mix-ups (see Figure 4-5 on page 4-11). Labels for common gases are provided as a part of
the standard installation hardware. (See Figure 1-3 on page 1-2.)
The default factory setting for this function is N
2
.
