Intermittent

[5]

Open to Close Number of switch count High to low transition

[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.
