Ultrasound ON/OFF
With some water in the base of the package holder, test the system is working by moving your finger
across the base of the package holder and toggling the switch between ON and OFF. You should
sense a noticeable difference.
Lasers ON/OFF
Test the system is working by toggling the switch to ON and you should see the two red laser beams
intersecting on the package holder. Toggle the switch back to OFF and the laser beams should
disappear.
Antifoam system
Use this option to check the level of antifoam remaining, and to test that the antifoam injector system
is working. This option is useful to purge the system before an extended stand-by (several weeks) or
when performing start up procedures.
Enter the number of injections required and follow this procedure:
1. An antifoam priming beaker is available from the spares kit delivered with the instrument. Place
this on the ultrasonic base of the instrument, using the lasers to center it and lower the plastic
front door.
2. Activate the motor to lower the instrument head, allowing the needle to penetrate approximately
to the center of the beaker. Refer to Manual displacement on page 20 for details on lowering the
instrument head.
3. Press the Start injection button and you should hear the injector working. You should hear as
many clicks as you have defined for the injection number. In addition, the liquid should be seen
exiting from the tip of the needle.
4. On completion of the test press the Stop injection button and raise the instrument head to its
home position. Remove the beaker and rinse well with water. Store with the syringe and antifoam
container for next usage.
Analog value monitoring
This screen shows all the main analog signals related to the main components of the instrument.
Global system view
This option allows you check various components of the instrument. Check a component by pressing
on the button/schematic (which will turn to green) and observe the values being displayed.
Note: If the gas flow rate is manually changed, be aware that the automatic purge procedure (every 5 minutes) will
reset the gas flow rate back to 0.25 mL/s, which will have an impact on the values being observed.
System initialization
Selecting this option initiates the standard system startup process without having to power the
instrument off and on.
End application
Select this option to perform an orderly shut down of the instrument. On completion, the instrument
can be powered OFF.
