14. Quality control

To ensure the instrument performs properly, it has to be checked
on a regular basis. In addition to the internal self-test, we there-
fore recommend control measurements with known positive and
known negative control solutions (e.g. Medi-Test Control REF
930 38).

14.1. Check mode

To get to the check mode, press the activity-button
find the check mode as the last option in the main menu. Within
the menu Check mode are three different options.

After the internal check, the instrument prints values for the in-

can send the LED values to our technical service to get initial
feedback on your problem.
