1. INSTRUCTION

The digital Luminance meter is a precision instrument used to measure

Luminance in candles per square meter (cd/m

) or foot-Lamberts (fL) in the

field.

It meets CIE photopic spectral response, f ’

≦6%.

The Luminance meter is compact, tough and easy to handle owing to its

construction.

The light sensitive component used in the meter is a very stable, long-life

silicone photo diode and spectral response filter.

Fullyfunctional for professional requirements.

Applications:

The Luminance meter is a handy, easyto use and precision measuring instrument.

It allows the accurate measurement of the luminance in cd/m

or fL.

1 cd/m

= 0.2919 fL = 0.0929 cd/ft

1 fL = 3.426 cd/m

= 0.3183 cd/ft

1 cd/ft

= 10.76 cd/m

= 3.142 fL

Contact Measurements

Placed directly on the surface to be measured:

Suitable for measuring

•monitors

•television screens

•light boxed

•light displays

Measuring at a Distance

The measuring angle being 2 degree.

Suitable for measuring

•monitors taking the existing ambient light into consideration

•lighting of streets areas

•lighting of sports areas

•lighting contrasts at work stations
