WitrynaSlow weighting uses a time constant of 1 second. Fast weighting uses a time constant of 1/8 second or 125 milliseconds. There is also a less commonly used weighting … WitrynaSlow - the needle would be damped to smooth the noise out to be easier to read. Slow corresponds to a 1-second time constant. Impulse - The Impulse time weighting is about four times faster than Fast, with a short rising time constant but a slow falling constant. Impulse has a rise time constant of 35 ms and fall time constant of 1,5 s.
