Simple test, pull 12 inches of Scotch tape off a roll quickly. Note that if you dangle it from your fingers, if you bring your other arm near it the free end of the tape will move over to that arm. Now Zerostat it. Do the same test. Using a properly functioning Zerostat the tape will hang straight down when you bring your other arm near it.
To recharge the tape to do the test again, just stick it down on a table and pull it up quickly a few times.
