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
Menu
. You
find the check mode as the last option in the main menu. Within
the menu Check mode are three different options.

14.1.1. Internal check
Once you press the activity-button
Internal check
, the instrument starts
a self-test. During the process, both the LEDs and the instru -
ment’s mechanics are checked for their operational capabilities.
After the internal check, the instrument prints values for the in -
tensity of the LEDs. If you have trouble with your instrument, you
can send the LED values to our technical service to get initial
feedback on your problem.
14.1.2. Control measurement
The activity-button
Control
measurement
initiates quality control measurements
with known positive and known negative quality control solutions.
To start a control measurement, press the activity-button
Control
measurement
.
The start screen appears and includes an activated worklist and
two measurements (NEG Test and POS Test).
Perform a normal measurement with negative and positive con-
trol solution (e.g. Medi-Test Control REF 930 38). Preparation
and the measurement itself are carried out exactly like a normal
measurement (see Measurement, chapter 13) . The results are
printed and saved.

To evaluate the results, read the instructions of the control solu -
tion manufacturer. In case you are using Medi-Test Control so-
lutions from MACHEREY-NAGEL, please refer to the reference
table provided in the instructions for evaluation.
We recommend performing tests with control solutions:
• In the beginning of every day
• When a new batch of strips is used
• When results are questionable
• Whenever the operators change
14.1.3. Stored data
The activity-button
Stored data
allows you to review the saved results
of your control measurements. The results are displayed in ex -
actly the same way as for normal measurements. However, here
you cannot enter sediment information.
You can print and send the data for control measurements with
the icons in the lower part of the screen.
