The one in the original post is almost certainly the same manufacture as the cheap ones at Sears. I just got one from sears, it's the $30 one they have on their website, search for multimeter. It is almost fully autoranging, no lux or RH, but it does have a K type jack and does capacitance and frequency. Not super accurate, but it was $20 on sale. Someday I will tweak the trim pots inside. I would never pay $50 for a cheap one like that on ebay. Sears guarantees their stuff, ebay is a money pit. If you want a light meter, buy a dedicated one from a camera shop. I prefer seperates anyway, so I can measure, say, light output and current at once.
