the test strip when the sample number is displayed, then
press the START button to commence reading. The
analyzer can be operated in two different modes:

Single Readings) (34)
Normal Mode
The Urisys 1100

system automatically waits for the strip
to incubate for 55 seconds before it reads the first test
pad. Seventy seconds after the START button is pressed,
the measurement is completed and the test strip tray
moves to the start position. Throughput in this mode is
approximately 50 strips per hour.
Fast Mode Option can be selected from the menu, the test strip is
measured directly after START is pressed. In this case, it
is up to the user to time the incubation period outside the
analyzer. Using FastMode enables a 30-second cycle to
be maintained.
u 8.4 Fast Mode (for Serial Readings) (38)
Each time a strip is read, the grey reference pad in the
test strip tray is evaluated to compensate for temperature
and aging effects that may influence the optical system. If
the compensation needed is excessive, for example
because the reference pad is badly soiled or an LED is
defective and cannot emit the required amount of light,
an error message is displayed.

The Urisys 1100
®
system assigns to each reading a
consecutive sequence number (sample number) having a
maximum of three digits. The sequence start number
automatically reverts to 1 each time the date is
incremented. You may, if you wish, reset the sequence
number to 1 via the New Ser. function, for example when
one series of measurements has been completed and
another is due to begin.
