Are you new to using a multimeter? Do you sometimes get confused by the symbols on the display? Or are you just a little unsure sometimes with the reading? Never fear, the Multimeter Wizard is here! With our fun little app you just use your multimeter to take a reading, enter it into the app, select the same prefix (M, k, m or µ) as being displayed on your multimeter and the reading will be automatically converted to its basic unit (V, Ω or A). That's it! If you want to better understand how the conversion is done you can simply pull down the results drawer and the conversion steps will be shown in detail.
