Abstract
PURPOSE: To secure an automatic correction for the double integration type A-D converter by correcting the division ratio between the variable dividers provided before and after the counter which obtains the digital value of the A-D converter and according to the error.
CONSTITUTION: The time duration signal which is delivered after converted through analog-time converter 4 is applied to gate circuit 6 to give the intermittent control to the clock signal supplied to counter 7 from clock signal generator 5. Variable divider circuit 16 is provided to the supply line of the clock signal to carry out correction. In this case, the standard division ratio is set through standard preset setter 17. Then the reference voltage is applied to input terminal 4a, and the count value of counter 7 is displayed on display unit 15. In case the count value is out of the standard value, the contents of counter 7 is taken into latch circuit 18. And the measured value is given to preset terminal group 16a of divider 16 to correct the error.
