Abstract
PURPOSE: To suppress the increase in the number of elements and to increase the generality of circuit, by common use of the 2N notation counter for the fast feed and halt time every period N times in detecting the decrease in the cell voltage.
CONSTITUTION: At normal operation, the output of the BLD circuit 4 is 0, the AND gare G9 is opened and the stop motor 6 is driven with the 1/10Hz signal. When the cell voltage is lowered, the output of the BLD circuit 4 is 1, the 60 notation counter 3 counts the signal in 16Hz, and the step motor 6 is operated in 30 steps with 16Hz signal at the same time. After the movement of pointer, the input C of the counter 3 is selected into the signal of 1/10Hz and the drive signal of the step motor 6 is stopped until 30 pulses are counted. After that, the first operation is repeated to tell the lowering of the cell voltage.
