RADIOMETER:
l)
The radiometer should be used in continuous mode only!
To ensure proper curing, the output light intensity should be measured prior
to each time curing is performed.
A built-in curing radiometer allows the operator to evaluate the curing unit's
performance. The aperture is located above the display. A series of molded
circular steps assist in alignment of the fiber optic light guide with the
aperture. The display will automatically convert to radiometer mode when
light from the light guide shines on the aperture.
accurately measure useful curing energy (wavelength range 400-510 nm in
curing lights) from 100 mW/cm² to 1999 mW/cm².
To measure curing light output: Press the C key on the keypad, then
center the tip of the fiber optic light guide (7mm or larger) over the aperture
as shown in Figure 12. Activate the light. Be sure that the tip is positioned
flush against the aperture so very little light escapes. Allow the display to
stabilize, and read the output in mW/cm². After an accurate reading has
been obtained, turn the light off and the display will return to it's former
function. The following is a guideline for interpreting the results:
UNDER 200 mW/cm²
200 - 300 mW/cm²
300 - 800 mW/cm²
OVER 800 mW/cm²
The radiometer will
Insufficient output: Do not use
curing light. Inspect lamp, filters, and
fiber optic light guide. Refer to section 7,
SAFETY PRECAUTIONS.
Increase curing time.
Use material manufacturers
recommended curing time.
High output: Reduce curing time
appropriately. Refer to Section
SAFETY PRECAUTIONS.
Calibration: The curing radiometer is factory calibrated and does not
require periodic calibration with normal usage as long as the unit remains
sealed. Normal usage includes checking curing light output each time
curing is performed. The radiometer may require calibration if the unit is
damaged.
To check other curing lights on the radiometer, turn the unit on. Activate
the Optilux 501 light by depressing the trigger. Position the other light
guide in the radiometer port and record reading.
Remember: The light guide must be 7mm or larger to receive an
accurate reading.
m) RECOMMENDED CURING TIME:
All Kerr curing lights will cure all visible (light cured) dental restorative
materials well within the recommended curing time suggested by the
material manufacturer.
To check the lamp-material curing ability use the Kerr Disposable
Hardness Disk, part no. 20399 as shown in Figure 13.

10. MAINTENANCE

CAUTION: Lack of periodic maintenance can cause inadequate
light output resulting in varying degrees of under curing of the
composite restorative material or excessive emission of energy outside
the curing range.
CAUTION: Before attempting to perform periodic maintenance
procedures, turn the master power switch S1 "OFF" (O) and disconnect
curing light unit from AC outlet (Mains). Allow the handpiece, lamp and
filters to cool completely!
Periodic maintenance performed by the operator will help ensure that your
7,
curing light continues to perform within specifications. Curing light output
must be measured frequently, on a daily basis for example, using a hand
held meter like the Radiometer (part no. 10503). Follow the guidelines in the
instructions included with the curing radiometer. In addition, on a monthly
basis, visually inspect the optical components in the handpiece for
degradation:
