problems with sequential AC volts measurement

[Gilson Fernandes]

I'am use a NI-4060 to measure some AC volts (the range is 127V to 220V with 60Hz). If I take the measures sequentially without put a Delay between the measures, the NI-4060 measures AC volts that does not exist, It seems that the NI-4060 have an buffer to integrate the measures, and doesn't empty it to do other AC measurement. The question is, exist one way to realize sequentially measurements without put a delay between it?

Hey Gilson,

You should not have any problem measuring AC Voltage with a DMM on one channel. Are you switching the DMM between two different channels? If that is the case, you might need a delay for settling time while the board adjusts to the new voltage. How fast are you sampling with the 4060 board? What software are you using to take these samples?
