4 Measurement
There are two distinct measurement procedures for test strips and
one for cell tests. The both procedures for the test strips are very
similar and differ only in the first steps. Each measurement proce-
dure is test-specific. The procedure is transferred to the instrument
via the bar-code strip. All steps involved to obtain the result are
displayed on the screen. Please also refer to the respective
Reflectoquant® package insert!
Measurement procedure A
In this procedure, only the reaction time of the Reflectoquant® test has to be con-
sidered.
How?
1. Switch on the instrument by pressing the ON/OFF button.
2. Press the TEST button until the arrow indicates the desired test-method memory.
3. Compare the first three digits of the batch number of the Reflectoquant® pack.
This reference number must be the same as the one displayed (otherwise recali-
brate, see page 10).
4. Press the START button. The reaction time is shown on the display.
5. Immerse the test strip into your sample as described in the Reflectoquant®
package insert (Reflectoquant® pack) and at the same time press the START
button (A). Carefully allow excess liquid to run off via the long edge of the
strip onto an absorbent paper towel. The countdown function of the instru-
ment is activated, the remaining reaction time is shown (countdown) (B).
6. An acoustic signal and the blinking strip five seconds before the end of the
reaction time requests you to insert the strip all the way into the strip adaptor.
The strip can also be inserted before the five seconds have expired (see the
corresponding package insert).
7. The measurement result is shown in the display in the units for the respective
test, e. g. mg/l, and is automatically stored.
