This sensor just converts current to voltage trying to maintain the curve shape as long as the bandwidth is enough. But the device has a certain zero offset, a certain non-linearity and a certain asymmetry. Can you deduce what the combined effect of those will be on the transfer accuracy when the RMS value is what you're after? Rob. |

| yes these are very nice... | 01/01/70 00:00 | |
| BIG leads | 01/01/70 00:00 | |
| They are nice but!!!! | 01/01/70 00:00 | |
| Linearity.. | 01/01/70 00:00 | |
| RMS? it measures current | 01/01/70 00:00 | |
| AC current has a RMS value too ... | 01/01/70 00:00 | |
| No integration performed | 01/01/70 00:00 | |
| I know | 01/01/70 00:00 | |
| That obviously depends | 01/01/70 00:00 | |
| True.. | 01/01/70 00:00 | |
Linearith errors often less problem than bw for RMS | 01/01/70 00:00 |
