Abstract

PURPOSE: To remove initial voltage and be able to alter spans by means of the dividing ratio of a variable divider by preventing the supply of pulses to a counter until the pulse counter counts the pulses of the stated number.
CONSTITUTION: Voltage to be measured is applied from input terminal 1 to analog part 2 and the output of analog part 2 is entered into control circuit 3, so that a gate signal with a pulse width proportioned to the input voltage can be obtained at the output terminal of control circuit 3. The gate signal controls open/close of gate 6 and gates clock pulses from clock pulse generater 7 and counter 8 counts the output of gate 6, so that the digital value corresponding to the input voltage can be obtained. In this case, variable divider 9, pulse counter 8 and gate 11, which is controlled to be opened when pulse counter 10 counts the pulses of a stated number and starts to supply the output of variable divider 9, are set on the prior stage of counter 8.
