I am narrowing down your multimeter list to purchase a new one soon and was looking at the Brymen BM857. In column H (uA, best DC current resolution) it says 10nA but instead either green, white, yellow, or red for high, average, low or danger, it is a tan color that looks like it was maybe missing feature. However the tan color isn't the same as with your legend so figured it meant something else. What does that color mean in your table?
