I'm curious as to why measuring the current through the device is an unsure method in your mind. I do realize you would have to take into account of the duty cycle of the pulses which would lower the current "observed" on the meter considerable, if not unreadable. That is the limitations of your meter ... not an unsure method.Fourth, if you have no DIODE function, hook your meter in series with your LED and see if it is drawing any current. Again, less of a sure method then number 3 or number 1.
You are correct. That is essentially my worry with this method, but if he has the ability to power the LED with a steady source (like the 9V mentioned) then its a good method.I'm curious as to why measuring the current through the device is an unsure method in your mind.

I do agree the IR card or the Diode test function are better methods with a GP DMM.
thanks sir can you give me procedure how to check i am new in this fieldhi,
if you insist on an analog multimeter, then do a diode check procedure.
