AI-110 mA calibration

[Anton]

Hi,

Is there any way to read the calibration constants in the AI-110 or otherwise determine the exact resistance of the 100 ohm resistor in the mA input circuit?

Hi Anton,

Thanks for your post! I have found an article that should answer your question:

Measuring the 100Ω Resistance on [c]FieldPoint Current Input Modules

I hope it helps. Have a great day!

Best regards,

Steven

Thank you, Steven, that's helpful.  I never would have guessed that the unit needs power to see the resistor. 

I still wonder about getting at those calibration values...

I am glad this helped Anton! I am looking into obtaining the calibration constants for these modules, however, out of curiosity, what will you be using these for? Please let me know. Thanks!

Best regards,

Steven
