7. Do not mount the 275 Mini-Convectron Vacuum Gauge in a manner
such that the deposition of process vapors, upon the internal surfaces of
the gauge tube, may occur through line-of-sight access to the interior of
the gauge tube.
8. Do not install the 275 Mini-Convectron Vacuum Gauge Module where
high amplitudes of vibration are present. Excessive vibration will cause
forced convection at high pressure and provide erroneous readings.
9. Do not bake the 275 Mini-Convectron Vacuum Gauge electronics
module at temperatures greater than 85º C.
10. Do not install the gauge tubes where they will be subject to corrosive
gases such as mercury vapor or flourine which will attack the gold
plated sensor.
11. For greatest accuracy and repeatability, the 275 Mini-Convectron
Vacuum Gauge should be located in a suitable room temperature
environment.
12. All connections to the 275 Mini-Convectron Vacuum Gauge are to be
made with shielded cable(s). The shield(s) are to be connected to the
connector shell.
