    i will check the others. thanks a lot!

    ah i see, thanks for prevention and explanation, can i use a varistor instead to avoid this complicated circuit and im afraid i can't find this ics either ?

    thank you so much! yes i want to complicate it but im not an expert therfore i can't change it or add other compononents on my own so i have to follow a schema and your advices thanks for help again ^ ^

    i ve read about NCP346 it says that it requires external schottky diode to prevent reverse current, Is it necessary?are all commercial multimeters operating this way or there are other circuit diagrams ?

    Hi Milen,thanks for this great project! sorry for the late comment i would ask you if i can remplace zener diode of the voltmeter with other protection components because i couldn't find a low current leakage one ? and about resistors can i use 5% tolerance resistors ?
