measuring CFL voltage
Pirateguy:
so i took the circuit out of a cfl bulb and tried to measure the voltage it outs out
to the tube, but i can't get a steady reading on it.
all i get is either 0.5v-ish and with only 1 probe attached i get 1.5v-ish (both unstable)
so i looked around and what i read is that they usually put out around 60 volts.
i tried several of these circuits and several meters, all results are the same.
why can't i measure this?
Pirateguy:
ugh, nevermind.
follwing youtube tutorials verbatim had me using the wrong pin :S
ultrarunner2018:
You won't get the correct voltage unless there is a CFL bulb connected to the output. The circuits are designed specifically for that type of load, which is not constant. Also, the frequency of AC (or pulsating DC) applied to the bulb is not 60Hz. It is usually much higher.
Pirateguy:
i see.
i will do some measuring with a load, thanks for the tip! :)

Nice way how to kill your multimeter.
