The aperture grid is etched stainless steel grid? And how to connect? about os-ims HOT 3 CLOSED

Hi,
can you explain?

from os-ims.

You need to ground your supply as specified by the manufactuer. I would ground that grid to the same ground as your amplifier. The grid is a wire set or the etched grid as specified in the paper. The electronic diagram as depicted is correct. I'm not sure how else describe it other than through a schematic.

Thanks for explanation.
Electronic schematic is correct but the missing part is the common ground (for negative terminal) for all the setup. Schematic is just for shutter grid part it does not say any thing about the whole circuit (setup). In the setup we have to use 4 power sources, one for Amplifier, one for Pulser, one HV source for ESI and one HV for electrodes. I could not find any explanation for ground terminal (negative terminal).

From your explanation I will connect shutter grid' ground (negative terminal) with amplifier' ground (negative terminal).
