QWhen the MR8880 is set to perform RMS calculation, how is the data updated?
AThe MR8880 has an RMS conversion circuit, and the output of that circuit is sampled based on the high-speed or real-time function setting. The RMS conversion circuit’s “0% to 90%” response time for rising (0% to 100%) input is 300 ms (it has the same response for falling input). Since the output from a circuit responding at 300 ms is being measured, it is not possible to track rapidly changing input, even if a sampling rate of 1 ms were used.
