recently acquired a CMA system with Auger System Control electronics. problem is, the digital panel meter is missing, so instead it was used in the past by hooking it up to a multimeter. i am trying to figure out how this thing works and in the user manual it is constantly referring to the DPM, which we don't have. one thing i am to observe is the readout on the DPM in terms of eV. my question is, how would one go about interpreting the voltage readout on a multimeter to understand what one is getting in terms of eV? and if you are wondering, i am a student lab assistant and the professor doesn't know about the system either because we acquired it from a retired professor. thanks for your help.
