analog discovery voltage concern


ab

Question

i recently bought an analog discovery kit.

upon wiring up a specific circuit for my class i noticed that i was not getting 5 volts from the discovery.  When i put my multimeter on the red and black wires to test, i got no voltage.  the waveforms software indicates a status of "ok" and 4.8 volts at my usb.  why do i not have 5 volts needed.  (my instructor says that i should have 5 volts)

Dear ab,

Could it be possible to see the circuit that you wired up? it would give us a better view and may help us understand what could be wrong. I did go through and make a quick circuit and I was also getting about 4.8 V. I will read through some of the reference manual to see if there is a reason for this. if you could post a picture of your set up that would be fantastic.

Thanks,

Bobby

Hi ab,

Just a follow up question on my end. Did you also make sure to enable/turn on the power supplies in the "supplies" section of the Welcome Tab for Waveforms2015? You won't detect any voltage without the positive (and negative if you so choose) enabled.

Thanks,
