Hello,
I connected 3 potentiometers to 3 channels, seems like only the first one works fine (the data curve looks like a horizontal line before move, straight line with slope during move, horizontal line when stable). The second channel gave me the signals with little vibration before any move, so I cannot decide which number is the initial value before any move. The third channel turned out to give me horizontal line during the whole process. I thought it might be some problems with the channels, so I connected my potentiometer to another channel, which still gave me horizontal line this time. I have no idea why this happened, could someone help me with this? why can't I get any signals after the connection of potentiometers?
Thanks.
