4 Preparing the Stabil-Ion System for Operation
4.7 Convectron Gauge Calibration Memory
Using the N 2 calibration to pressurize a vacuum system above about 1 Torr
with certain other gases can cause dangerously high pressures which may
cause explosion of the system. See Section 4.6.1 on page 4-12 before
using with other gases.
Granville-Phillips calibration data is averaged over a number of
nominally identical Convectron Gauges and programmed in
memory. All Stabil-Ion Systems with the Convectron option are
supplied with this feature unless source 2 is specified.
If the Convectron Gauge calibration is for a gas type other than
N 2 (or air) we suggest placing a label near the second and third
lines of the display indicating the gas type or types used for
calibration to prevent mix-ups.

4.7.1 Memory Module for Convectron Gauge
New data for each gauge can be transferred to the internal memory using a Memory Module which
has been programmed by Granville-Phillips. The Convectron Gauge destination for the data
contained in the Memory Module is predetermined at the time it is programmed and is stored along
with the data. The data is individually serialized, and the serial number is printed on the module's
label as well as being stored electronically in the memory.
Data for Convectron Gauges A and B are stored independently, and must be loaded from separate
Memory Modules.
4.7.2 Using a Memory Module for Convectron A or B.
1. Turn off power.
2. Open front panel door.
Protect the Memory Module from static electricity. Touch a grounded,
unpainted metal surface on the 360 Control Unit and then touch the surface
of the anti-static bag before removing the Memory Module from its bag.
3. Using a high impedance grounding wrist strap or other effective antistatic protection, remove
the Memory Module from its antistatic packaging. Save the antistatic packaging.
4. Plug the Memory Module into the data port with the writing on the module label right-side-up.
See Figure 4-17.
