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.
Additional Troubleshooting
- What are the nominal gain settings for the Instrumentation Amplifier?
- I am using a third-party electrode with your Electrode Amplifier. How do I calibrate the electrode in Logger Pro 3?
- I am performing an experiment that requires both positive and negative voltages to be measured. When using your ULI with a Voltage Probe, it only reads 0 to 5 volts. What can I do to measure both positive and negative voltages?
- How do you use a DIN or non-AutoID Instrumentation Amplifier with a TI Graphing Calculator?
- Could I use one of your interfaces to connect the output of my third-party GC to your software?
