Light Meter (Radiometer)
Use the Sapphire Plus light meter to validate the power density (light intensity or
mW/cm
2
) output of the curing handpiece prior to each use. The light meter window is
located below the system control panel.
CAUTION: DO NOT USE 2 mm OR 4 mm TIPS ON THE LIGHT METER WINDOW
(the Radiometer)
When the curing tip is placed on the light meter window and the lamp is activated, the
system automatically detects the light and changes to the RADIOMETER mode. The
output reading of power density is shown on the display windows. To get an accurate
reading, the curing tip must be centered directly in the light meter window. Set the timer
to 5 seconds and remove the tip from the light meter window as soon as you have a
measurement.
Proper Light Meter Readings
• Curing: If light is below 300 mW/cm
2
, do not use for curing. High light intensity (over 1500 mW/cm
2
) allows fast
curing. Use curing test rings provided to test the material being cured.
• DO NOT USE THE SAPPHIRE FOR CURING OR SINGLE TOOTH BLEACHING IF THE LIGHT OUTPUT
IS GREATER THEN 3000 mW/cm
2
. Call DenMat and return the instrument for repair if the output is too high
or too low.
Curing Mode
Timers and Control Panel Operation
There are two operator-adjustable curing timers available: C1 and C2. Each timer
can be set from 1 to 10 seconds. It is recommended that multiple 5-second
exposures be used for resins that need a little more time.
WARNING: Single exposures longer than 5 seconds must be limited to use with
the 12 mm curing tip. They can only be used, with careful monitoring of the heat
build up inside the patients mouth. Use air flow to remove heat and help reduce
heat buildup.
Whenever the curing handpiece is inserted, and cure mode selected, the system
defaults to the first of two curing timers. The factory preset time for both of these
is 5 seconds. The indicator light next to CURE on the control panel will turn
on. The display windows will show “C1” in the MODE window and “05” in the
SETTING window.
The exposure time setting can be increased or decreased by using the UP and
DOWN arrow keys on the CONTROL WHEEL. The exposure time setting can be increased or decreased by
using the UP and DOWN arrow keys on the CONTROL WHEEL. Each time the UP key is pressed, the time will
increase one second; each time the DOWN key is pressed, the time will decrease one second. The time displayed
in the SETTING window will display the time as it changes. Each of the two curing timers can be adjusted from 1
to 10 seconds using this method.
When the timer setting is adjusted, it will stay at that setting until the next time it is changed,
even when the system power is turned off. This allows the operator to use favorite settings without
having to reset before each usage.
