Operations
Determine the maximum counting speed of the counter by
evaluating the input conditions listed in the table at right.
Counters with "-M" suffixes offer the option of manual or external
resetting. To manually reset the counter, press the reset button
located to the left of the display window. To prevent an accidental
reset, lock the reset button by sliding the button downward, without
depressing it. A small "click" sound may be heard, both when
locking and unlocking the reset button. Slide the button up to
unlock.
