TMechCounter - is a meter that has some specific features: digit capacity. The quantity of the displayed numbers is equal to the digit capacity of the meter, even if the left numbers are zeroes. It is also imposible to input numbers more than the digit capacity allows. overflow flag. So as this meter does not count more than the digit capacity allows, so reaching the maximum, it begins to count from the zero,but it must be marked by the feature of zero overflow reversibility. It can count to the both sides,as for the increasing, so for the decreasing. This option can be turned off. Using this option, points 1 and 2 are cosidered. The meter display can not be below zero, but the zero overflow is possible (to the opposite side).Can be used in programms of taking stock of meter displays of any mechanical meters: for electricity, water, gas etc.
