MAVO-SPOT 2 USB
Is equipped with an excellent adaptation to the spectral brightness sensiti-
vity 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.
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 IEC 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.
