Troubleshooting

  • Primary Test: Confirm that the range setting on the sensor is appropriate for the device connected to the Instrumentation Amplifier.
  • Secondary Test (when using with a gas chromatograph): If your voltage readings are noisy, you should connect the Earth ground of the Gas Chromatograph to the grounding pin on the Instrumentation Amplifier.
