Q. Give suitable block diagram to explain the working of electronic multimeter.
Sol. An electronic multimeter is a laboratory instrument which is capable of measurement of DC and AC current, voltage and resistance. The multimeter is just like as PMMC meter. To measure DC current the meter acts as an ammeter with low series resistance. Range changing is accomplished by shunts in such a way that the current passing through the meter does not exceed the maximum rated value.
Basically a multimeter consists of an ammeter, voltmeter and ohmmeter combined with a function switch to connect the appropriate circuit to the D' Arsonval movement.
