#170598 - Linearith errors often less problem than bw for RMS Responding to: ???'s previous message |
It is reasonably easy to correct for repeatable linearity errors.
But you also have to consider drift, ageing, and bandwidth. The bandwidth controls the numbers of overtones you may see, and is often the most important factor when deciding how exact the RMS measurement is. But since you do not know what the input waveform looks like, you will not be able to compensate. If you did know what the waveform looked like, then you wouldn't need to measure any RMS. |

| RMS? it measures current | 01/01/70 00:00 | |
| AC current has a RMS value too ... | 01/01/70 00:00 | |

| That obviously depends | 01/01/70 00:00 | |
| True.. | 01/01/70 00:00 | |
