Thanks @noguchi-takahiro, I'll have you do a round of revision with @ngadiyar93. Then I am realizing that we'll need you to make these same changes here as well --> source is here. |

@noguchi-takahiro this sentence as is isn't quite grammatically correct.
Can you improve it to say that Either LA-55P or LA 100-P can be used with this design based on the sensing range desired (and provide the sensing range as you are currently doing).
Also please include a note saying that LA-100P has a variant SP/13 which has a different gain that users must be careful about when ordering.

@noguchi-takahiro Thank you for updating the document and the BOM.
I have a minor change request that I have indicated in-line. Please let me know once you have fixed it.

Thanks, @ngadiyar93 I changed the sentences that you mentioned. And please review it and let me know of further improvements and requests. |

@noguchi-takahiro Thank you for updating the document.
I have left you a couple of items which should be pretty quick to address.

@noguchi-takahiro can you update this line as follows:
Based on the sensing range desired, the current measurement card can use either LA 55-P or LA 100-P from LEM. These sensors have an open aperture and PC pins. The LA 55-P can measure +/-55A while the LA 100-P can measure +/-150A.

@noguchi-takahiro Can you add the Note about the LA 100 series variants in a separate line with the word "Note" in bold as follows (please refine the language to be better than what I am saying):
Note: The LA 100 series has three variants LA 100-P, LA 100-P/SP13, and LA 100-TP. The sensor gains of each of these variants are different, which has implications in the choice of the burden resistor. The rest of this document is specific to the LA 100-P variant.

| The open aperture was a requirement as it allows for the range to be easily scaled down just by adding turns to the primary. | ||
| The LA 55-P is a closed loop compensated hall effect transducer that has an accuracy of +/-0.65% and linearity of <0.15% which is quite good compared to other sensors from LEM. | ||
| It has an excellent bandwidth of 200khz and a low impedance current output that is inherently more immune to noise than a high impedance voltage output. | ||
| The LA 55-P is a closed loop compensated hall effect transducers that has an accuracy of +/-0.65% and linearity of <0.15% which is quite good compared to other sensors from LEM. The LA 100-P has an accuracy of +/-0.45% and linearity of <0.15%. |

transducers, please update to be transducer since it is singular.

Thank you, @ngadiyar93. Please review it again. We also need to address this below.

Thanks @npetersen2. Good catch. I did not mean to close this PR. |

This PR is to add information on how to use LA100-P to AMDS documentation.
