TROUBLE SHOOTING GUIDE
If the SonoCheck
TM
does not change color or if the time required to generate the color change takes longer than normal,
please check the following guide:
Problem
Reason
Corrective action
De-gassing
Dissolved gasses will absorb ultrasonic energy
De-gas solution according to equipment man-
ual
Water level
Ultrasonic energy may reflect off of the surface of the
solution and change energy distribution
Check equipment manual for correct water
level
Operating cycle time
Time varies with the amount of ultrasonic energy
available
Longer operating cycles generally provide bet-
ter results
Instrument load
Heavy instrument loading and certain materials can
absorb ultrasonic energy
Look for weak points using the periodic func-
tional test and check for ultrasonic absorbent
material like silicone or plastics
Transducer failure
Transducer efficiency may decrease with age. Indi-
vidual transducers may fail while others in the equip-
ment continue to function
Perform periodic functional test, placing Sono-
check monitors in each transducer location
(see equipment manual)
Low energy
Transducer inefficiency or the ultrasonic basket may
absorb too much energy
Check performance without basket in place.
Compare performance against another ultra-
sonic cleaner if available. Call for service
