Diamond Monochormator ion pump operation instructions

Protection Mode trip
If the pump stops due to a Protection Mode trips shortly after turning it on, the HV light (amber) will flash. This most likely means that the pump cannot start because pressure is still too high.

- Press Start Prot to disengage the Protection Mode (green light should be off)
- Press HV ON/OFF so that the HV light is off
