Very disappointed with this meter. The manual is outdated and therefore not at all useful. The 800 number isn't really up to date either...took a while to find out how to change date and time. Then started to try and test...no calibration chip included, as indicated in manual...finally tried using one of the strips as a calibration chip..that worked, but I had used an entire box of strips in an attempt to get a valid cholesterol reading, not to mention the number of times I had to stick my finger.
Bottom line, wouldn't recommend this meter under any circumstances! I returned mine and got a credit to my credit card..thankfully!
At minimum, the company should update the manual sent with meter..that might make a big difference...perhaps there are things that can be done on how the meter works...which are completely unknown and therefore, your testing is in vain and of no value.
I finally got readings of 4.9 on my cholesterol and then reinserted the same strip and got 3.5...same sample, different readings, readings that had no meaning what so ever...I sent mine back the next day.
