Critical warning: Never attempt calibration without the official manual adjacent. Incorrect zeroing can offset the entire logarithmic response.
The analog output is on the 15-pin D-sub connector (J5).
The manual specifies: Pressure (Torr) = 10^(Vout - 8). For example, 6 V output = 10⁻² Torr; 4 V output = 10⁻⁴ Torr. mks astron 2l manual
The installation section of the MKS astron 2l manual is non-negotiable. Here is a summarized protocol:
Over time, adsorbed gases on the grid can cause outgassing, leading to false high-pressure readings. The manual details two degas methods: The analog output is on the 15-pin D-sub connector (J5)
Before diving into the manual specifics, it is crucial to understand what the Astron 2L is—and what it is not.
The manual for this device is critical because the Astron 2L operates with high voltages (up to 180V for the ion collector and 500V for the filament bias). Mishandling can lead to electric shock or destruction of the fragile gauge filament. The manual specifies: Pressure (Torr) = 10^(Vout - 8)
