I have a USB-1616HS-4 that i just got to replace a USB-2416. i switched modules to get the faster DA rate. i have the 1616 set to 10-khz. I have the signal wires of a load cell connected to the CH0 and CH8 terminals. i also tried connecting the ground from the 10-volt excitation voltage supplied by an external source to the S (signal ground) terminal but didnt see any difference. When i have Instacal open and start the analog test i can see a stable voltage from the load cell that changes when load is applied to the load cell. the voltage displayed would be what i would expect and it all looks good. but when i attach a digital meter to the analog input module in DL, i just see a bunch of jumpy numbers that dont look at all like what i see in Instacal. how do i get a nice stable voltage reading from my load cell in DL that matches what Instacal shows me? i have tried averaging modules and digital filters. the averaging modules just make the numbers jump around slower. the filter modules, one high pass and one low pass result in a 60-hx sine wave. what would be the best approach for connecting the load cell wires to the USB-1616 and what would be the best method in DL to get a solid cleans display of the load cell voltage? thank you
