aquiring 1 point while continual aquisition

[FIT Engineering]

We are continually aquiring data using our DAQ.  We are interested in Voltage over 2 V.  With the desired rate of collection we are collecting roughly 10 data points durring the time that the voltage is over 2 V before it dips below again.  We are wanting only 1 piece of data to use for each time that Voltage greater than 2 V is achieved. 

thanks

I'm sure there are more elegant solutions, but i would do something along the lines of:

low = true

loop:

if (input voltage>=2.AND.low)  {record.data.point, low=false}

if (input voltage < 2)  {low=true}
