I tried to measure the rms value of a small ac signal ( 6v rms, 50 Hz) using [c]FPAI-100 module. The control rate was selected between 1ms-10 ms. But
the rms value output using Basic dc rms .vi was not a constant value. But
simply the magnitude of individual samples and the constant rms value
(6 V) was not obtained. How to solve it?
