Hello,
We have a setup of two thermistor arrays (one array with 3 thermistors and one with 7 thermistors). Each array has it's own DT9829 DAQ and is wired in as a four-wire thermistor setup. We are sampling at 20Hz and we're currently getting periodic noise (1Hz) on the 7 thermistor array, but not the 3 thermistor array. Each array uses it's own twisted shielded pair cable with enough conductors for a four wire setup. We have turned off all external electronics and possible sources of noise, but still get the 1Hz sinusoidal noise. Any thoughts on this or potential fixes?
Thanks!
