Illuminance
From the start, the instrument measures and displays twice a second the
instantaneous value of illuminance expressed in Lux or fc. This value gives
information to users about illuminance local conditions.
Min. and max. values completes the screen.
User can at any time by pressing the keys :
: Reset minimum and maximum values
: Enable pause
: Continue measurement

Over-range
Under conditions of measuring range excess, defined at 150,000 lux, an over-
range pictogram appears. It comes fleetingly for an illuminance exceeding
150 000 lux . Displayed value will be 150.1 klux.

Power source
When the instrument is equipped with alkaline batteries, it can operate for 72
hours minimum. A symbol informs the user about electric power remaining. If
battery is low, less than 1 bar on the pictogram, the instrument stops measuring,
saves current measurement and switches off.
7
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.
8
Regular checking
Like most measuring instruments, it is strongly recommended to regularly control and
calibrate LX100 instrument. The sensor sensitivity decreases depending on measurement
durations and illuminance intensity. Return to the manufacturer each year will provide
necessary metrological traceability.
