Geiger HV resets the arduino problem
Posted: Sun Dec 15, 2019 10:29 am
I have MC34063 based 500V dc supply near arduino. The system works ok. But as soon as i try to measure the HV using multimeter probe, it resets the Arduino immediately. Seems like a surge or em spike .
Arduino is run by 5V supply
HVDC is run by 12 V supply
Both circuit share common DC ground for letting Arduino count Geiger pulses.

Why it happens ? The capacity of my supply is 500V and 1.3mA (milliamperes) sufficiently good.
