Keep hoping for an app that would apply a scaling factor to a MM reading. I use a MM to measure big amps in my car via Ohms input and so have to scale the mV to amps in my head and my arithmetic is rusty !! Any ideas welcome.
I’m working on a new iOS beta porting features from the Android beta right now. The new Android beta has a “math” menu, which currently supports power and thermocouple conversions. I’m planning on adding a scaling factor option.
