    In these configurations, the voltage bias is greater than 0V of the reference level. Therefore, the voltage bias of JY-6312 series input modules is not connected to the internal reference "ground" under any circumstances.
  • Page 26: Thermocouple Measurement Noise

    10.2.2 Normal Mode Noise Normal mode noise is typically generated by large AC power supplies that create magnetic fields that induce currents in the measurement loop. This noise generates current in the same direction JY-6312 V1.0.3 | jytek.com | 26...
  • Page 27 Let the measurement line intersect the high current line perpendicularly, thereby changing the direction of the magnetic field. Do not run thermocouples in parallel with power lines or other noisy signal lines. ◼ The normal mode current is reduced by filtering. JY-6312 V1.0.3 | jytek.com | 27...
