Warnings

– Protect the measuring device from heavy shock or falling down.

– Cleaning agents and other liquids must not enter the apparatus,

since they may damage it.

– Do not expose the radiometer to sunlight.

– Both the storage and use of other electronic devices in the imme-

diate vicinity of the apparatus may impair proper operation.

– Portable and mobile high-frequency communication

devices may affect medical apparatus. The use of mobile

phones during operation is not allowed.

– Repair work may only be carried out by a certified Ivoclar

Vivadent Service Center.

– Use only original spare parts.

– For dental use only! Suitable for measuring energy-rich blue light

in the wavelength range of 385-515 nm and not for white light.

Operation

1) Place the light probe directly to the

centering gauge and flush on the sensor.

2) Switch on the polymerization light.

Note: In order to achieve accurate

measuring results, only light probes with a

circular emission window must be used.

3) The Bluephase Meter automatically

switches on at a light intensity of at least

300 mW/cm

. A lower light intensity is

indicated with "----" on the display.

4) Hold the polymerization light above the

sensor for about 5 seconds.

5) The measuring result shows the power

density in milliwatt per square centimeter.

6) Switch off the polymerization light.

7) The Bluephase Meter automatically switches off after 20 seconds

of light exposure or 3 seconds after removing the light source.

What if…?

– … the Bluephase Meter shows a value below 400 mW/cm

400 mW/cm

is the absolute minimum of light intensity for poly-

merization lights. If the light intensity is lower, composites can no

longer be completely polymerized. Therefore, it is recommended

to replace a curing light with a light intensity of less than

400 mW/cm

–

… the measuring results correspond with the data

rovided by the manufacturer?

The polymerization light achieves the stipulated light intensity

and can therefore be used according to the curing recommenda-

tions of the respective manufacturer or stipulations of the

corresponding composite manufacturer.

– … the measuring results deviate strongly?

If the measuring results strongly differ from the manufacturer’s

data, the following procedure is recommended:

– Check the selected curing program.

– Clean the sensor of the Bluephase Meter (see Maintenance

and Cleaning).

– Clean the light probe with a disinfectant and a soft cloth.

Carefully remove any possible material residue, such as

composite material, from the light probe with e.g. fingernail

or a plastic spatula. Do not use sharp or pointed instruments,

since they may scratch the surface of the light probe and thus

reduce light transmission.

– Check light probe for damage. If the light probe is held

against a light source and certain segments appear black,

then the glass fibres are broken. In this case, the light probe

has to be replaced with a new one.

If these measures do not improve the results, the curing times

have to be prolonged respectively in order to achieve sufficient

polymerization. The following standard applies: With half the light

intensity, the curing time has to be doubled (e.g. the measured

light intensity is 500 mW/cm

while the data stipulated by the

manufacturer is 1000 mW/cm

with 20 seconds of curing time; in

this case, the curing time has to be doubled to 40 seconds).

– …“LO“ is shown on the display?

A low residual capacity is repeatedly shown by ”LO“ on the

display. The batteries have to be replaced as soon as possible.

– …the display does not show anything?

– After 20 seconds of exposure to light (e.g. also sunlight), the

Bluephase Meter automatically changes into the stand-by

mode. Remove the light source before you conduct a new

measuring. If still no measuring is possible, cover the sensor

with the hand for a short time.

– If these measures do not improve the results, check the

batteries and replace them, if required.

– If there is still no display upon exposure to the light of a

curing light despite these measures, send the Bluephase

Meter to a certified Ivoclar Vivadent Service Center for repair.
