What is the sample rate of the High Speed (HS) inputs?
The Nexus® 1250 meter will sample the HS inputs at up to 2 independent rates, depending upon the configuration of the unit. The HS inputs can be used for either pulse accumulation or for status change to record a waveform. The HS inputs are always sampled at 100 times per second, and debounced for 2 sample times. Your pulse rate needs to be within its tolerance. If the Nexus® meter has been ordered with the optional 2 meg or 4 meg memory and the user has selected the HS input to be used for waveform recording, the HS inputs are sampled at a rate that is based upon the user selected waveform sample rate which is much faster than the pulse counting rate. The unit will record the waveform instantaneously based on the change of a status input.
