5. Foil Test
Tip: Remove tray to ensure foil test is accurate
5.1 How to perform foil test:
i)
Complete the usual start process
ii) Use a strip of ‘home’ brand aluminium foil about 150mm long x width of
roll.
iii) Make sure Lid is closed
iv) Press TEST Key to switch on ultrasonic and unit will run for 30 sec as
programmed
v) Open the Lid and insert the foil vertically into the bath.
vi) Keep foil in the bath until LID is displayed
vii) Remove the foil and compare the number and distribution of
perforations with the sample foil test provided with your machine.
Refer Australian Standard AS/NZ 2773.1-1998, page 16 for more details.
NOTE: It is important to always use the same type of foil. It is
suggested that a test is performed, on reciept of the machine, of such duration
as to give a result similar to the sample provided. This will then become the
foil test time for that type of foil.
5.2 Foil Test Problem Solving:
If you are having difficulty getting a foil test to perform to standard, work
through the following items, then try foil test again.
5.2.1 Machine may require further degassing.
5.2.2 Detergent Type and Dilution.
i)
Always use a pH neutral or slightly alkaline detergent (pH 8 to 10.8)
that is made specifically for ultrasonic machines.
ii) Extra detergent may be added to overcome water quality issues.
Tip: Check detergent bottle is full, check that same brand is being
used, and check bottle and hose are connected and that there are
no kinks in the line.
5.2.3 Contact your service agent if you cannot achieve a satisfactory foil test.
N.B. As per AS/NZ 2773.1-1998, it is acceptable to use alternative methods of
testing the performance of your ultrasonic machine. Examples such as
aluminium disc and pencil test, UPM probe must be used as per
manufacturer’s instructions.
