Schematic changes are in for  current sense, probe compensation, cover lockout.

The volts are 0.08V when the current-to-voltage resistor shunt is  1/1000 of the target 30000 Ohm load,
and output is at 2400V.  I have not read ADC function yet, so asking here if that is a good range top.

Or to say it another way, "Is the ADC using much resolution at 0.08V and lower?"
"Does the STM323F401 ADC have any built in gain settings to boost small signals?"
