NPort 6250 
Reset Button—Press the Reset Button continuously for 5 sec to load 
factory defaults. Use a pointed object, such as a straightened paper clip or 
toothpick, to press the reset button. This will cause the Ready LED to blink 
on and off. The factory defaults will be loaded once the Ready LED stops 
blinking (after about 5 seconds). At this point, you should release the 
reset button.
