Generator cannot ramp 50 kV 0.6 mA

Hi, we faced a problem in our single crystal XRD. Have you encountered similar problems with you? it cannot reach for the tube to reach it’s set point 50 kV – 0,6 mA anymore. it is about 30 kV - 0.3 mA now, and diffraction patterns looks very weak,
Is this an indication that the tube or generator is dying? :cry: :cry:

If tube or generators is dying than you can not operate the system. I have an idea for you to check.
1. This may happen if one set HV manually. If you start experiment it preserve the manual settings. In BCP you can put system in standby mode and check if generator ramps to working values during the experiment.
2. Check the configuration in BCP. You may have limits for HV settings.
