Calibration - MERCK RQflex plus 10 Mode D'emploi

3 Calibration

When?
1. With a new instrument.
2. With a new batch of Reflectoquant® test.
The supplied bar code is valid only for the batch with which it is enclosed.
3. When scanning in a new test method of a new test.
How?
1. Remove the specific bar-code strip from the Reflectoquant® pack. Certain tests
require two bar-code strips.
2. Switch on the instrument by pressing the ON/OFF button and open the lid. The
display of F:50 indicates that 50 memory slots are available.
3. Press the TEST button until the arrow points to the corresponding test-method
memory where you wish to store the calibration.
4. Insert the bar code all the way into the bar-code scanner in the direction of the
en
arrow in a smooth motion from left to right, and then remove it again.
5. The calibration process is successfully finished when the left-hand three digits
of the batch number on the bar-code strip are displayed. In addition an acoustic
signal sounds. The small arrow in the display indicates the test-method memory
place (1 – 5) where the test data are stored.
6. Repeat this procedure until the acoustic signal sounds. Entry is now complete.
7. Return the bar-code strip to the Reflectoquant® pack. (Store carefully, but not
in the test-strip tube.)

Important
Overwriting a test method
• An already calibrated test method stored in the memory is overwritten when a
new bar code is scanned in.
• All measurement data stored for a given method is lost when it is overwritten.
• The blinking MEM in the display indicates that measurement data are stored. If
these data are still required, they can be individually called up by pressing the
MEM key and correspondingly noted.
Test methods that requires two bar-code strips
• After scanning in the first bar-code strip, test methods needing two bar-code
strips show the three-digit reference number and the symbol --- in the display
alternately.
• As soon as the second bar-code strip has been scanned in, only the batch refe-
rence number is shown.
• The sequence of scanning is of no importance.
