Nope, figure worse case the meter goes puff. Not about to stick my finger into that circuit thou. I suspect the first diode/capacitor multiplier put the voltage over -1000V, so at some point they changed the step-up transformer and didn't change the rest of the board (-: Have a good day
Likely the voltage was being exceeded earlier in the diode ladder. hence why the two diodes were in series and the capacitors too. As you go up the ladder you should reduce the capacitance to help control the load. The last diode and cap are wasted on that board (which makes me wonder why they didn't just pull them out of the BoM to save cost). I have modified one of those electric tennis rackets for zapping mosquitoes to have an extra large capaticor on the output for some more kick. I also took the time to re-lay out the components for better spacing but they were all properly rated so I didn't see any offects like you saw here. To get more kick out of this, you'd either need to triplicate that last diode and capacitor for voltage rating (you don't have enough space) or see iif you can find peculiarly high-voltage diodes and capacitors to fit inside on the pads, in which case you'd need to be sure you didn't get arcing across the components or creepage across the board.
Looks like someone did half of a job making it. I would have stuck a set of pads for a zero ohm resistor between the two diodes and the two caps so if the transformer had less secondary winding it could be adjusted. Strange to see extra components in the product, not very typical. But it does work and I would not plug it into a computer. Like the bug zappers, plan on stepping the voltage up on one to make a spark gap detector. Was less than ideal when I bought a bug zapper from a local retailer and the bleed off resistor was not installed, yet the holes were there. Have a good day
Talk about Crow barring a circuit.
Good circuit, nice circuit.
You don't have an isolation Transformer measuring high voltage?
