What fusing on the leads should I use to protect the phone against inadvertently placing across mains voltage?

if you don't know for 100% whether or not what you're working on is hot or not, than you shouldn't be working on it bro.

Cool project. I really want to do but I can't do it now, because my phone had died. :/

you probably tested a condutor with voltage

Not a bad idea but as a technician in my past trade and current hobby, I will always relay on my trusted Fluke meters. Perhaps Fluke will come out with one (unless they one already)

They do, although it is a Bluetooth interface for the 287/289 series multimeter. The actual measurement is done by the multimeter and it is sent to the phone via the accessory. Just for the sake of it, I own a 289 and I just love it, after a 179 and 115 series. If not the best portable meters surely in the top three.

I love this instructable. I can't wait for full multimeter modules to be available for smartphones.

something like this ?

I have multimeters in just about every tool box, and car (at least 6 or 7, spread about), but my smartphone is almost always on my hip. Between datalogging, and reduction in size, I am right there with you, in the "can't wait" group.

Great idea! Having a continuity tester in your phone is much better than having to carrying around a multimeter all the time.

what watt or volts are the 3k ohm resistor?

i like this and need one for my ground to antenna checking continuity...excellent might try to make myself...

Love the idea. Simple and easy to use. Do add a warning to remove any power from the circuit you are testing and make sure all capacitors are discharged, as your costly phone is at stake.

Thanks.. yes you are right.

I will surely add a warning.
