When using Buffered Output from systems like IRD8800, IRD7100, IRD7200 and IRD7400 for connection to Data Acquisition Hardware like NI cDAQ or NI cRIO or Gantner Q.Bloxx and Q.Station - we recommend that 2 core shielded cable should be used. Please do not use cable without shielding as it will induce noise into the measurement and the final reading may become 4 to 5 times more than actual reading. To ensure final reading is in tolerance - please use 2 core shielded signal cable for each channel.
