This circuit uses battery powered. It makes an encode driver to drive LEDs of MAN-4 display one by one through multi-channel transit way, then to reduce the power consumption of battery. Because the reading which people seen is still have impression in whole display cycle, so the display seem to display continuously. The peak current of display is 20mA, the test duration of each LED only accounts for 12.5% of the whole display cycle. Four MC1402/8 FCSR, to latch the value which is form MC14518 count chain,then itaccomplishes the multi-channel transit function.
