PRODUCT TESTING
Test the LED Light Attachment with the Radiometer
It is highly recommended that curing capability be tested using a hardness disk to ensure a
!
complete cure. When a hardness disk is not available, light output can be verified with a
radiometer to estimate curing effectiveness. Failure to perform either of these tests may lead to
incomplete cures of dental restorative materials.
The Demi Ultra Charging Dock Radiometer should be used only with the Demi Ultra when fitted
with the 8 mm LED Light Attachment. Use of the radiometer with other curing lights or with
larger/smaller diameter light sources may result in inaccurate measurements.
Verify the Demi Ultra performance before each use using the radiometer built into the Charging Dock:
1. Set the curing time interval for a 10 second cycle.
2. Verify that the radiometer sensor is free of debris that could impact the accuracy of the measurement. If the
radiometer sensor requires cleaning, clean it per instructions in Product Care and Maintenance.
3. Carefully hold the unit so that the lens of the LED Light Attachment is flush with the radiometer sensor
(Figure 6) and centered within the circle provided.

1. While holding the unit steadily in position, press
and release the LED Light Button. In response to
the bright light, the radiometer indicator lights will
illuminate from the bottom up, providing a reading
of the light intensity.
2. Wait until the light goes off before moving the
LED Light Attachment away from the radiometer
sensor.
Caution: Do not use the Demi Ultra for curing if
!
less than 3 Radiometer lights are illuminated
The bottom two lights are amber, the top three lights are blue. The first blue light must be illuminated for the
curing light to operate in a normal mode. Do not use the Demi Ultra for curing if only the amber lights are
illuminated. Reference the Troubleshooting section for possible solutions.
The lower four indicator lights emit a steady glow. The top indicator light is sensitive to the Periodic Level
Shifting (PLS) of the LED Light Attachment, causing a blinking or flickering effect.
