2.5.1 Ion Gauge Cables
Do not attach cables to glass gauge pins while the gauge is under vacuum.
Accidental bending of the pins may cause the glass to break and implode.
Cables, once installed, should be secured to the system to provide strain relief
for gauge tube pins.
Ionization gauges are safe for use only if all exposed conductors on the gauge
and on controller and on vacuum system are grounded.
