Analysis
Prepare the samples for analysis as described under
Sample Preparation
. Once the
samples have been prepared and allowed to cool for at least 5 minutes, the method chosen, and
the meter calibrated (including any blank determination), analysis can begin. The

the read cycle, a progress bar will indicate how far along the convergence process is as a
percentage of the maximum 2 minutes allowed. Up to 20 samples can be analyzed before a
recalibration is required. Additionally, if the ambient temperature changes by more than 5°C or
if the one-hour timer expires, the program will prompt for a fresh calibration.
Remove the electrode from the rinse solution and wipe the body carefully with a tissue.
