Lock for parameter setting:

–Only the correct password enter, the user can modify the presetting values

Lock for panel button:

–One set to disable the front button function (except SET key)

Preset initial count value function: Any desired value can be set on the unit as the initial count value of the counter. The counter will add to or subtract from the set value.

For example, you set 10 as the initial count value, and after every reset, the display will show 10.  The default setting is 0.
