I need to view the current draw curve of a capacitor charged to 150 volts as it discharges into an inductor.
My scope is a Tek TDS1012. I'd like to view the voltage drop across a resistor in series between the capacitor and inductor. The scope ground would go to the resistor input and test lead to the resistor output.
I'm concerned because the ground becomes 150 volts above the scope ground. The scope is rated for inputs up to 300 volts.
Is there a procedure for doing this without cooking the scope?
