Pressure Watcher


Pressure Watcher

In brief

This software logs and graphically displays values available through BCS webpage, most typically pressure of the cold-cathode gauge in the analysis chamber. The reading happens in the specified time Interval [s] (minimum is 5 seconds). The logged data can be Cleared and Saved in ASCII format. The total Exposure calculated in langmuirs (1 L = 10-6 Torr × s) is shown.

The graph can be manipulated by mouse as following:
  • zoom by left-click dragging from top left to bottom right
  • unzoom by left-click dragging from right to left
  • pan by right-click dragging
For a typical use see Exposing the sample with gases.

Further details

The software can be used for logging any values available on webpages, as defined in the Settings. These settings can be stored in .ini files (Save settings) and loaded when needed (Load settings).

For calibration of the calculation of the total exposure the read pressure values can be lowered by the set Base pressure [Torr] and multiplied by the Multiplicative constant.
