5.3.3. Duplicate testing
If duplicate testing is desired, enter the same patient identification number for channels 1 &
2 or 3 & 4 twice. The mean result will automatically be printed along with the individual
channel data.
If the duplicates differ more than 7.5% from the mean
value, the mean result will be flagged with ‘X’ !
Pressing key “0” during optic activation, will activate all
channels in duplicate mode
5.3.4. Starting the Analysis
Place the required number of cuvettes in the cuvette pre-warming positions. To continue
with the PT example, pipette 25 µL of sample to each cuvette well. Press the “Timer 1”
button to start the stopwatch. Place the Thromboplastin / CA mixed reagent with magnetic
stir bar in the center large reagent pre-warming position.
Transfer the first cuvette with sample to the measurement position. Once patient
identification numbers have been entered, press the Optic keys again to activate the
channels.

When the timer has reached 1 minute, pipette 50 µl of mixed Calcium Chloride and
Thromboplastin reagent into the first cuvette position. If autostart is enabled, the optic will
start automatically. A beeping noise will indicate the start of the reaction. Repeat for the
remaining cuvettes. The reaction can also be started either by pressing the optic key or by
using the Autopipette, which electronically triggers the optic channel.
In summary, press the optic key once for patient identification data entry, press
again to activate the channel, and a third time if manually initiating the reaction.
(Do not press a third time if using the Autopipette to start the reaction or if
autostart is active).
If using the Autopipette,
- always pipette from left to right (channel 1 - 4)!
- Disable the autostart function in the SETUP SYSTEM
