#158203 - 5 to 6% accuracy Responding to: ???'s previous message |
In fact, we consistently achieve 5-6 percent accuracy for a given load for RMS current measurement (of course, the slow response factor works in favour), discounting the linearity issues, which we correct with a look-up table. Look up table is again, not that complicated, since we do the tabling using a windows software, where response graph can also be input which is then straightened out with the table. |
