CHARGING THE BATTERY
Note: Fully charge the battery before the initial use.
1. The CINEBRATE battery will charge whenever the AC Adapter is connected to the instrument.
2. If you purchased the optional External Charger, the time for a full charge is 10 - 12. To use the charger:
a. Make sure the charger power supply is properly connected to the charger and an appropriate
AC power source. The AC input range is 100 to 240 VAC, 50 –60 Hz.
b. The battery and charger are keyed. To insert the battery in the charger, make sure the keys are
aligned and push the battery as far forward as possible.
c. There are three status LED’s on the charger, MED, HI and MAX. Depending on the charge state
of the battery, the LED’s will blink in succession. For example, for a fully discharged battery the
MED, HI then the MAX lights will blink one after another. For a partially charged battery, the
MED light will be solid, and the HI and MAX lights will blink etc. Once the battery is fully
charged, all three LED’s will remain steadily lit.
d. Remove the battery when fully charged.

FIGURE 12 - CINEBRATE RESULT SCREEN
THEORY OF OPERATION
The CINEBRATE is a true Spectroradiometer. It collects the optical radiation (light) through the objective lens.
The signal then passes to the diffraction grating (see Figure 15). The grating breaks up the light into its
component wavelengths much like a prism turns white light into a rainbow. A broad band light such as sunlight
is composed of a large number of different wavelengths of light. When the diffraction grating is exposed to this
type of light, it will refract the light at several angles thus creating a diffracted spectrum much like a rainbow.
Similarly, if the grating is exposed to a source such as a laser, which emits a nearly monochromatic wavelength
of light, only the wavelength(s) of the laser will be refracted.
FIGURE 13 –SPECTRUM MEASURED BY THE PR- AND CINEBRATE
The wavelength range is 380 nanometers (nm) (violet) to 780 nm (deep red) –the visible spectrum of the
electromagnetic spectrum (see Figure 13).
The diffracted spectrum is then dispersed onto the detector. The detector is comprised of 128 individual
elements. Each of the detector elements in samples a unique color.
380 nm 500 nm 600 nm 780 nm.

C I N E B R A T E User Manual

During a measurement, the optical radiation (light) is sampled for a period of time determined by the Adaptive
Sensitivity™algorithm. Adaptive Sensitivity automatically determines the correct integration (exposure) time
based on the available signal. Following the light measurement, a measurement of the dark current of the
detector is made for the same length of time that was used for the light measurement. The dark measurement
is then subtracted from the light measurement yielding the contribution of light for each detector element.
FIGURE 14 - PR- / CINEBRATE SIMPLIFIED BLOCK DIAGRAM
FIGURE 15 –CINEBRATE SPECTROMETER DIAGRAM
The uncorrected or ‘raw’ spectrum is corrected using factors established during the factory calibration of the
instrument. These factors include wavelength accuracy correction, spectral distribution correction and
photometric correction.
Next, the data is corrected by spectral factors. These factors insure that the spectral power distribution (SPD) of
the target and calculated values such as CIE Chromaticity are accurately reported. Lastly, a scaling factor
(photometric factor) is applied ensuring the luminance is displayed.

The corrected spectral data is then used to calculate photometric and colorimetric values including luminance,
CIE 1931 x, y chromaticity coordinates, and correlated color temperature (CCT).
