26 Troubleshooting
Check your cleaner periodically to test the level of activity of the
ultrasonic cavitation. Frequency of testing will depend on your use of the
cleaner.
Glass Slide Test
You will need the following equipment:
Frosted microscope glass slide (1” x 3”), such as ESCO #2951F, or
equivalent;
No. 2 lead pencil; and
General purpose household cleaning solution, such as
“Dawn” liquid
soap.
Test procedure:
1. Prepare a fresh solution with general purpose household cleaning
solution (concentration 1%) and warm tap water (120º - 140ºF).
2.
Fill the cleaner to within 3/8 inch of the “operating level” line.
3. Turn the ultrasonics on for at least five to ten minutes to allow for
degassing.
4. Prepare the glass slide by first wetting the frosted portion with tap
water.
5.
With the No. 2 pencil, on the frosted portion make an “X” from corner
to corner.
6. Immerse the frosted end of the slide into the solution. Hold the slide
vertically and center it in the solution.
7. Make sure that model CTH cleaners are in SET SONICS mode, not
degas mode, then turn ultrasonics On.
