Light Meter (Radiometer)

Use the Sapphire Plus light meter to validate the power density (light intensity or mW/

cm2) output of the curing handpiece and lesion detection handpiece prior to each use.

The light meter window is located below the system control panel.

CAUTION: DO NOT SHINE STM LASER BEAM ON THE LIGHT METER WINDOW

CAUTION: DO NOT USE 2mm OR 4mm TIPS ON THE LIGHT METER WINDOW

When the curing tip or lesion detection handpiece 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 and the lesion detection must be centered directly over 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.

NOTE: It is recommended that measurements are entered into a log in order to document any changes in output

over time.

Proper Light Meter Readings

• Curing: If light is below 300 mW/cm

, do not use for curing. High light intensity (over 1500 mW/cm

) allows

fast curing. Use curing test rings provided to test the material being cured.

• Lesion Detection: Light intensity must be 75 mW/cm

(displayed as “00 75” in the display windows) or

greater. If light intensity is below 75 mW/cm

, do not use.

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 should be used for resins that need a little more time. Single exposures

longer than 5 seconds should be limited to use with the 12 mm curing tip.

Whenever the curing handpiece is inserted, and cure mode selected, the system

defaults to the ﬁ rst 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.
