Hi all,
I just got my m2k device and wanted to test it for the first time. I breadboarded a wheatstone bridge with a potentiometer and downloaded Scopy. I want to supply +/-V from the m2k while measuring the bridge voltage using the voltmeter function. This is what I was trying to do when I noticed that when activating the power supply only the negative supply shows a measured voltage; the positive supply stays at 0.000 VDC. I tested tthe supply with a digital multimeter which confirmed the readings from Scopy. Well, it actually measured 13mV on the dead supply, but it's a cheap DMM with questionable accuracy.
I'm wondering if my unit is defective and warrants an RMA from Mouser, or if there is something I'm doing wrong here.
Thanks!
Mark as solved
