Using the instrument
Functions
The instrument is operated by three push buttons:
To switch on the instrument and to screen
the main menus and the sub menus.
To enter and activate the menu selected
by the Select button.
To exit the current menu or function.
The menu
Four main menus are available for selection:
Main menu/Calibrate instructs the instrument to
measure the White Calibration Device.
Main menu/Enter test contains sub menus correspon-
ding to each of the NycoCard
®
tests that are available.
Main menu/Options contains two sub menus:
- Enter language: To change the language on the display.
- New white: To measure a new value of white when a
message “Error Recalibrate” appears on the display.
The white value will change with ageing, even if pen
tips and calibration devices are replaced.
Main menu/Off followed by “ENTER” will turn off the
instrument. Pressing QUIT and ENTER simultaneous-
ly will also turn off the instrument, regardless of the
position in the menu.
Operating procedure
The following three steps must be performed before
the result of a NycoCard
®
test is obtained:
1 . Adjusting
Make sure that the pen is placed in
the penholder and turn the Reader on.
The instrument automatically performs
“Adjusting”. Allow the Adjusting proce-
dure to complete without touching the pen. A single
beep will indicate that the Adjusting is completed
correctly. A double beep will indicate errors in the
Adjusting followed by the message “Adjust error”.
(See troubleshooting).
2 . White calibration
Press ENTER to activate the menu and
follow the instructions in the display.
When the message “Place pen…” is
displayed, lift the pen out of the holder
and place it on the White Calibration Device. Hold the
pen steady until a single beep indicates that the cali-
bration is finished.
3 . Measuring a NycoCard
®
test
The Reader pad (7) should always be
used during measurements. The reque-
sted NycoCard
®
test is chosen from Main
menu / Enter test and the instrument is
ready for the measurement. When the pen tip is placed
into the test hole and the pen sleeve pushed down, the
measurement will start. After a few seconds the test
result will be displayed as a concentration value.
If the instrument is placed on stand-by for about 10
minutes, it will automatically switch-off. When the
instrument is turned on again, the last measured value
will automatically be displayed.
Maintenance
The Reader pen has two replaceable accessories, the
pen tip (14) and the pen ring (13). These two parts will
be in contact with the assay devices that are exposed
to diluted blood/urine. The pen tip must be replaced if
it is dirty, to reduce interference during measurements.
Be careful not to touch the optics of the Reader pen.
It is recommended that the pen tip and white calibra-
tion device are inspected regularly. If the calibration
device is damaged or dirty, it should be changed.

Replacing the pen tip: to remove the pen tip, care-
fully snap the tip off with your fingers. Replace the
