MAVO SPOT 2 USB
This high precision luminance meter
for distance measurement with an acceptance angle of 1° is assigned to class B in accordance with DIN 5032-7, appendix B of DIN EN 13032-1 and CIE 69.It measures the perceived brightness of back-lighted surfaces in candelas per square meter (cd/m²) or foot-lamberts (fL) in consideration of ambient light.
Is equipped with an excellent adaptation to the spectral brightness sensitivity of the human eye V(λ) and is highly precise with a minimal deviation of just f1‘ < 3 %, which is significantly better than specified in the standard. By means of the mirror reflex optics, the measuring subject may be targeted precisely in a 15° field of view and a sharply marked 1° measuring circle in the center of the viewfinder. Focus can be set for distances ranging from 1 meter to infinity. Shorter distances as of 34 cm are made possible by means
of optional close-up lenses. Alternatively, contact measurement can also be performed with an optional, top quality probe. The velvety coating on the adapter disc prevents scratching of self-luminous and back-lighted surfaces.
Measurement functions are selected and measurements are started with convenient on-hand operation. The display on the viewfinder is activated along with back-light by simply pressing a key. The comparative and ratio measurements are especially advantageous, by means of which deviation of measured value B from reference value A is evaluated and displayed. The relationship A/B is used for contrast measurement at workstations. Percentage deviation %A allows for an assessment of the consistency of monitor screens and projection screen lighting, and difference A-B is used to detect deviation during the production process. Special tests for proving and observing norms and standards for quality, general safety, work protection, as well as safety on monitors in the field of medical diagnostics and office technology may get its documented evidence by means of our factory Calibration Certificate. Depending on how the meter is used, we recommend a calibration interval of 12 to 24 months.

Specifications
MAXIMUM PRECISION
Classified spot metering of luminance with an acceptance angle of 1° in cd/m² or fL in accordance with class B per DIN 5032-7, appendix B of DIN EN 13032-1 and CIE 69.
BROAD MEASURING RANGE
High initial sensitivity and a resolution of 0.01 to 99,900 cd/m² or 0.01 to 30,000 fL.
CONVENIENT EVERYDAY USE
Simple operation with one hand, easy to read viewfinder display, compact design, ¼“ tripod thread, protection during transport in high quality aluminum case.
NON-VOLATILE MEMORY
1000 measured values or 10 groups of 100 measured values can be saved, retrieved or transmitted to a PC via the
integrated USB port.
PRECISION FOCUSING
The mirror reflex with a 1° measuring circle and a 15° field of view is laid out for distance measurements from 1 meter to infinity, with optional close-up lenses for focusing as of 34 cm.
CONTACT MEASUREMENT
Contact measurement can be performed with an optional probe and adapter disc.
COMPARATIVE AND RATIO MEASUREMENT
Contrast A/B, consistent lighting %A and deviation A-B are calculated and directly displayed.
EIZO RadiCS
The meter is integrated into the software and can be used for comprehensive testing and automatic adjustment of RadiForce monitors, in order to assure constant and consistent image reproduction.
V(λ) ADAPTATION
The spectral sensitivity of the silicon photodiode is color corrected and corresponds to the spectral brightness sensitivity of the human eye V(λ).
COMPUTER-AIDED MEASUREMENT
The meter’s continuous operating mode is assured thanks to power supply via the USB port. Meter control, as well
as acquisition, display and storage of measured values, is managed with included GLUX 2 software.
