Hi to everyone, I'm new here. While i was reading the AD2 specifications I noticed that Analog Input and Voltmeter have some differences in the accuracy: is there any technical explaination? Why the Analog input has a 0.5% more?
Installed WaveForms 2015 on my Mac. First it didn't detect the device. Followed instructions on https://huelectronics.wordpress.com/2015/03/02/digilent-waveforms-for-macs/. Then device was detected. I can see the heartbeat LED blinking. But the device doesn't seem to be working. To verify I put it in Voltmeter mode, and fed 2.5V into it directly. The current value is very small. Voltmeter shows 13mV. Is there any problem with the device?
Here is a summary of my issues, my Teacher's Assistant's response, and the results of further troubleshooting: --------------------- I am having trouble with what I would expect for some of the voltages in the H0-2 lab. I have successfully completed the first portion of the lab. Now I am attempting to measure the voltages with the voltmeter. I was connecting the + voltmeter end to the red power source and the -v end to the black ground. With the power supply on, the reading was about 2.76V. I thought this may be due to some resistance or bad wiring, so I directly connect
