Hello,
I am new to this group, and could use some help. I am developing a system,
using both a TS-7200, and a TS-ADC24. The TS-ADC24 is connected to sensor
board, with 8 current sensors (ACS756). These sensors have an output of 2.75V
DC when the DC current is 0A. I have all the sensors connected, through voltage
followers, to the AD1 header of the TS-ADC24. I am using a 2xVref as voltage
reference (5V), and sampling at 100 Hz.
When I sample, channels 0,4,8,12,16,20 show the correct values (around 2.75V,
except for channel 0, which is not connected to anything), but channels
2,6,10,14,18 and 22, show a 4.9988 voltage. I have looked at the samples taken
with the second group of channels, and they don't vary at all. Now, to discard
any problems with my program, I used the tsadc1624ctl program, with the
following command:
tsadc1624ctl -m 7200 -b 0 -s 0,2,4,6,8,10,12,14,16,18,20,22 -n 100 -r 100 -x
02VS -B 10000 -o csv
I get the results shown below. As you can see, the problematic channels aren't
showing any measurement, but when I measure the inputs with a multimeter, it
indeed show the 2.75V.
However, when I connect the problematic channels one by one (2,6,10,14,18, 22),
they do show the correct value.
I am at a total loss right now. Any help is appreciated. Thank you.
