i was suppost to have gotten 4.01 and 7.01 calibration solution, but instead got 10.01 and 7.01. will this still work and be accurate, or should i wait for the 4.01?? also, i have a question about the storing solution.. how much do you use, a few drops, fill the cap halfway? and, can the solution stay in the cap for long for multiple uses, or do i need to fill it every time i use the meter?
