Measurement Procedure B - MERCK RQflex plus 10 Mode D'emploi

Measurement procedure B

Besides the reaction time of the Reflectoquant® tests this procedure also considers
other waiting times.
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 waiting time appears in the display, e. g. 120 sec
(A). Proceed as described in the respective Reflectoquant® test package insert.
Press the START button again to activate the stopwatch function (B). When the
waiting time has expired, a strip symbol appears in the display and the reaction
time of the test, e. g. 60 sec, is shown (C).

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.
