hi! i want to build an ammeter with icl7107 for my variable power supply (the one on this site) but i ran into a problem with this schematic because one of the inputs is tied to the ground and i cannot use it at rhe same time with this voltmeter. but the schematic on this site has floating inputs and i would like to use it. so if you couuld please tell me how turn it into a ammeter.
what i know so far is that i have to add a low value resistor on wich the voltmeter will measure the voltage. that value will be in amperes. so how can i calculate the power resistor on wich the voltage is measured. i know so far that is Ohm's law, is there a specific value for the ic that you have to konw?
thanks.
Hi, did u got any solution for your problem coz I'm also facing same thing. Thanks
