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
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.
Rim detector
Select this option to check that the rim detector is working correctly. If any faults are reported, these
must be corrected before using the instrument for measurements.
Ultrasound ON/OFF
Check the box to turn the ultrasound OFF or ON. 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
switching between ON and OFF. You should sense a noticeable difference.
Lasers ON/OFF
Check the box to turn the lasers OFF or ON. Test the system is working by switching to ON and you
should see the two red laser beams intersecting on the package holder. Switch to OFF and the laser
beams should disappear.
