4. If the unit has a heating function, set the temperature to the required
level. Note: the same temperature should be used each time
measurements are taken. (See page 6 for information on the effect of
temperature.)
5. Once the fluid is degassed and the
required temperature is achieved,
start an ultrasonic cycle. Insert the
probe into the cleaning fluid while the
ultrasonics is running.
6. To take a reading, press and hold the
button on the meter. Record the
results displayed on both the
Frequency and Power displays.
Note: it is important that only the
stainless-steel probe wand comes into contact with the cleaning fluid. If
the handle, connector or display unit gets wet, it may damage the Meter.
7. The probe should be placed in the 18 measurement positions and the
results recorded. For consistent measurement, the Probe should be
placed in the same 18 locations each time measurements are taken.
8. Record the results so that future tests can be compared. log book is
available from Ultrawave for recording the results. If there is a reduction
in the readings over time, your ultrasonic cleaning system may not be
working at full efficiency and may need validation and servicing.
Note: It should not be expected that the Meter will give readings of 100% every
time. The hygea
®
Ultrasonic ctivity Meter is designed to be used as a
comparative measurement device over a period of time.
The hygea
®
Ultrasonic ctivity Meter has been optimized for use in Ultrawave
units. The Meter should not be used to compare the performance of different
baths but should be used as a comparative measurement of the performance of
one individual bath over time.
