Error monitoring
If an error occurs during operation of the TTR 91 R then the status LED will turn red to indicate an error and the

Error indication
Error condition Output (V)
Broken filament or tube removed 0.5
Calibration error 0.5
Bakeout
In some UHV applications it is desirable to bake the vacuum system components in order to achieve a lower base
pressure. The tube of the TTR 91 R can be baked to 150°C, but the electronics housing must be removed.
Referring to the figure in section 6.7, remove the electronics housing. When baking the tube on your system, do not
exceed 150°C. Always allow the tube to cool before refitting the electronics housing.
