Reader Reviews
The LCD diplay on these units (I have purchased two, now, with the identical problem) is so bad that the units are essentially unusable. The LCD display contrast is very, very low. (it is hard to believe that the contrast is even 10:1? (a good LCD computer monitor is about 500:1)) Even under the best lighting conditions, carefully holding the instrument just so, etc. the units are hardly even readable. I have 1) replaced the batteries (both the batteries that came with the units and these replacement batteries tested fully charged) 2) carefully adjusted the contrast (being unusable is the BEST that I could get, any other contrast is hopelelly worse) 3) reset the unit, etc. After the problem with the first unit, I looked at the Amazon.com reviews and the reviews did not mention this problem. I therefore, reasonably, assumed that this first unit was defective and so I arranged to exchange it for another one. Unfortunately, the second unit's display is equally abominable so I assume that this very unfortunate defect is intrinsic to the product. Comment | | (Report this)
