My TPS-Compact is lingering in the "ramp" state (status LED is blinking with 400 ms period) and reaching only 3e-5 Torr. The front Pressure Display Module shows "00" and I don't know what that means (no mention of this in the manual). This morning before venting, the pressure in my connected small chamber was 4e-8 Torr (system working correctly). I can't totally rule out a small leak in my vacuum system, but I'm concerned there may be an issue with the turbo pump - maybe the controller? I don't have any sort of read-out connected to the pump, so I don't know the final relative speed of the turbo blades. Has anyone seen the Pressure Display Module show "00" and know what that means?
