    Its sensor is composed by a silicium photodiode, which spectral response is the photopic curve according to CIE standard. LX 100 instrument is mainly an efficient and easy- to-use instrument : with small size, it has a large display with a resolution of 64*128 pixels, and involving a very high technology.
  • Page 5 Luminous flux The luminous flux of a source is the assessment, according to the sensitivity of the eye, of the amount of light radiated throughout the area by this source. It is expressed in lumens (lm).. Luminous intensity The light intensity is the luminous flux emitted per unit of solid angle in a given direction.. It is measured in candelas, equivalent to 1 lm / sr.

    Keyboard presentation When being switched on, “measurement screen” is displayed . From this screen, the operator has access to three others screens by pressing on keyboard; return to measurement screen is obtained by activating Function keys Directly associated with texts to displayed shown above on display they measurement setting.

    Accessible from principal measurement screen by successive pushes on key , those different screens allow instrument setting. They also inform users. Screen control To optimize display reading, the operator can : 1. Adjust brightness by pressing on function keys. 2. Backlight LCD display for a better reading in a dark place. “No”...

    Servicing The LX 100 conception allows a reduced maintenance, which consists in changing batteries and cleaning the instrument and sensor with a slightly dampened cloth. A particular attention must be paid to the white disc covering the silicon photodiode which surface must not have dirts or scratches Regular checking Like most measuring instruments, it is strongly recommended to regularly control and calibrate LX100 instrument.
