Page 4: Introduction
LX200 luxmeter is a photometer for measuring illuminance, it is equipped with a photoelectric detector and with a silicon photodiode coupled with a filter to modify its response and to get it as closed as possible of the reference function V(λ) defined in the CIE (International Commission on Illumination). - Page 5 Luminous flux The luminous flux of a source is the evaluation, according to eye sensitivity, of the quantity of radiated light among space by this source. It is expressed in lumen (lm). Luminous intensity Luminous intensity is the luminous flux emitted by solid angle unit in a given direction. It is measured in candela, equivalent to 1 lm/sr.

Page 6: Factor Value According To The Light Sources
Factor value according to the light sources The following table indicates the factor value corresponding to different light sources with their examples. The device is adjusted with an incandescent standard white light source owning its own spectral response. The following lighting sources have a different spectral response. Therefore, the presented coefficients in the following table enable to correct the measurement according to these different sources. -
Page 7: Operating Principle
Keyboard presentation When being switched on, “measurement screen” is displayed. From this screen, to go to the 4 different measurement screens, press on key. keys are associated to each measurement modes. key allows to access to reading setting or data transfer screens. To back to measurement screen press key. -
Page 8: Setting
3 – Setting screens About Calibration Brightness Accessible from the principal measuring screen by successive pushes on the key, those different screens allow setting of the instrument. They also inform users. Brightness To optimize display reading, the operator can : 1. -
Page 9: During Measurement
Unique range The digital processing of the instrument avoids for the operator the choice of a measuring range, LX200 displays the result of the measurement in lux or fc on all of its dynamic. To cover the whole field, different formats and units are directly displayed. Lux mode Footcandle mode Instantaneous illuminance... -
Page 10: Uniformity
Uniformity Principle: From sampled data, the instrument calculates and displays on the measurement time: Instantaneous value at the rate of two displays per second Average value Max and min values Uniformity of illuminance: définined as the min / average ratio. From start screen (a), here is how to proceed to calculate the uniformity on a time controled by chronometer and clock: Inst access to measurement screen Uniformity (b). -
Page 11: Temporal
Temporal Principle: The operator can follow the evolution of illuminance during a period of time at un fixed poste or not fixed. Ex : evolution of street lighting on a firelane. Inst access to measurement Tmp (b). The measurement is not launched yet. Press on 1s to choose the sampling rate. -
Page 12: Mapping
Mapping Measurement principle: The instrument allows to make a manual report of measurement point in an area to obtain a graphic representation of the distribution of the intensity of illumination. To do that, before making measurement, you have to define: 1. - Page 13 Colonnes : 1 Make a measurement of mapping with LX 200 instrument: From start screen, here is how to proceed to make a manual report of points and get a mapping of a room/area: Inst access to measurement screen Cart (b).
- Page 14 Measurement error: To make a new measurement in case of handling error or ambient condition unacceptable, press twice Pt key to back to the coordinates of the last poin to re-measure. Make the measurement, validate and continue the sequence normally. On the same principle, press Pt key the required number of time to back to the sequence of measurements already made (points et columns) and repeat the entire sequence of measurements.

Page 15: Instrument Shutdown
Instrument shutdown In case of accidental shutdown of the instrument (low batteries), results are automatically saved when the LX200 is operating in Temporal mode. For other modes of measurement (Instantaneous – Relatve - Uniformity – Mapping), please check battery level before launching dataset. Data reading After a requested shut-down of measurement and a data storage, it's possible to consulte dataset results: Proceed as follow:... -
Page 16: Data Transfer
Data transfer This screen allows data transfer toward a computer trough USB cable. LLX20 software have been previously loaded into the computer (see notice of LLX 20 Software ). Access Data transfer screen : Link the instrument to the PC with a USB cable. From start screen of the instrument, press 3 times key until the obtention of the data transfer screen. -
Page 17: Running Informations
Servicing The LX 200 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. -

Page 19: Measuring Capacity And Storage
Measuring capacity and storage You can make 32 datasets with the luxmeter. Files can be memorised according to their modes: Uniformity – Temporal – Mapping. Each dataset can contain 16370 values. Uniformity mode: • Max 24H of continuous measurement: 01J 00:00:00 Temporal mode: •... - Page 20 Once returned to KIMO, required waste collection will be assured in the respect of the environment in accordance to 2002/96/CE guidelines relating to WEEE.
