With 8 differential or 16 single ended channels available, my device is measuring seven Type J thermocouples and one analog 0 to 5V signal which is an output from a strain gauge process meter (2 wire output). The seven TCs are differential. The remaining two channels are currently configured as single ended channels. The positive lead of the analog output from the meter is connected to one SE channel and the negative lead is connected to analog ground. The result is noise on all TC channels. Please confirm the preferred connection and configuration. The user guide describes the differential connection with a 100Kohm resistor between the channel low and analog ground.
