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.
CAUTION
The Demi Ultra Charging Dock radiometer should be used only with the Demi Ultra when
fitted with the 8mm 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:
Set the curing time interval for a 10 second cycle.
1.
Verify that the radiometer sensor is free of debris that could impact the accuracy of the measurement. If
2.
the radiometer sensor requires cleaning, clean it per instructions in Product Care and Maintenance.
Carefully hold the unit so that the lens of the LED Light Attachment is flush with the radiometer sensor

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.
Wait until the light goes off before moving the LED Light

Attachment away from the radiometer sensor.
The bottom two lights are amber, the top three lights are blue. At least one blue light must be illuminated for a
proper cure. 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.
