Patent abstract
Current is measured in an ionization device that includes a high voltage supply, and an emitter electrically coupled to the HV supply. An opto-isolator is provided that includes a light source and a light detector. The light source has a current flowing through it. The light source is electrically coupled to the emitter. The output of the light detector is measured. The output of the light detector is related to the current flowing through the light source.
