i'm not sure what you mean about the EV range of the meter though. something about the range of the light meter?

I presumed it meant the range of lighting that a meter inside a camera can measure. As I not technically minded I thought I'd leave it at that but found myself doing a bit of research. I came acorss this thread on APUG
http://www.apug.org/forums/archive/index.php/t-22339.htmlA more 'layperson' type answer is:
Exposure value. A method of quantifying scene brightness in order to take photo. For practical photography purposes, the meter expresses a dynamic range from 'how low' to 'how high' a range of apertures, speeds, isos can allow the same amount of light to reach the film. My Rolleiflex T has a very handy EV range set on a moving scale so once I've got a correct shutter speed and aperture measure and set, I can then move the EV scale and still get the same amount of light in but at a different spped/aperture combination
A meter that with an EV1-EV20 range means that it could measure brightness levels from just above the light level of a candle light to a brightly sunlight scene on a snow capped mountain. There are some great handheld light meters that can measure the light from the moon (Gossen
Lunasix). Whether hand held or in-camera, the wider the numeric range means that the meter can handle broader range of exposure latitude.
Bringing it back to the Instax 200 range of 10-15 means it can't measure a very wide range of lighting conditions, perhaps the reason why the flash fires so easily.
