run of the VI. Therefore, you could get a maximum output value that 
is not related to the current set of collected data. 
Max & Min function (Functions»Comparison)—Takes two numeric 
inputs and outputs the maximum value of the two in the top right 
corner and the minimum of the two in the bottom right corner. Because 
you only are interested in the maximum value for this exercise, wire 
only the maximum output and ignore the minimum output.

Wire the terminals as shown. If the Maximum Value terminal were 
inside the For Loop, you would see it continuously updated, but 
because it is outside the loop, it contains only the last calculated 
maximum.
Note
Updating indicators each time a loop iterates is time-consuming and you should 
try to avoid it when possible to increase execution speed.
