1. Detects intermittent Opens or Closes lasting for at least 250 μsec.
2. Test current of 0.5 mA with maximum open circuit voltage of 2.8 V is used.
3. Maximum count reading: 199.99 M (display “OL” when achieving 2 x 10

and thereafter).
4. Count only low to high transition for initial switch condition of Low.
5. Count only high to low transition for initial switch condition of High.
