Abstract

PURPOSE: To achieve small size and light weight, by constituting the common usage part for the meter and counter in the multimeter having the frequency or frequency measuring counter function with a simple circuit constitution and using the crystal ocillator for watches.
CONSTITUTION: The count latch section 18 counting the output from the reference oscillator 16 is reset, set enable and latched with the count start signal and end signal outputted from the A/D converter 14 operated with the output of the reference oscillator 16 at the multimeter function. Further, when the count section is taken partly as 60 notation system, highly accurate watch function can be obtained by using the crystal oscillator to the reference oscillator 16.
