2.2. FUNCTIONS OF THE INSTRUMENT
The C.A 1110 is a lux meter. It is used to make illumination measurements from 0.1 to 200,000 lux, in the visible part of the spectrum,
to the exclusion of electromagnetic radiation that is not visible (X rays, ultraviolet, infrared, microwaves, RF, audio frequencies, etc.).
It is used to check the illumination on work surfaces or trafc zones, in accordance with the recommendations of the AFE (Association
Française de l’Éclairage - French Association of Illumination). Sound management of illumination saves energy.
The instrument can also measure the decrease of illumination over time due to the aging of luminaires and to the dust that is de-
posited on them. The luminaires can then be cleaned or replaced before the illumination falls below the minimal allowed threshold.
This preventive maintenance serves to preserve good visual comfort.
This instrument is easy to use. It has extensive stand-alone capabilities and can be used:
to display illumination measurements in lux (lx) or in foot-candles (fc),
to record a minimum, an average (mean), and a maximum in a specied period,
to record a minimum, an average (mean), and a maximum on a surface or in a room,
to record the measurements,
to communicate with a PC via a Bluetooth link or a USB cable.
The Data Logger Transfer software can be installed on a PC and is used to congure the instruments and to recover the recorded
measurements.
2.3. FUNCTION KEYS
Key Function
SRC
MAP
A short press on the SRC key serves to select the type of illumination source: F11 uorescent, LED, or other
source (default). See §8.1.
A long press on the MAP key is used to enter the MAP mode.
MEM
REC
A short press on the MEM key records the measurement and the date.
In MAP mode, pressing the MEM key adds a measurement to the measurements of the MAP.
A long press on the REC key starts or stops a recording session.
UNIT
A short press on the key switches on the back-lighting.
A long press on the UNIT key displays the measurement either in lux (lx) or in foot-candles (fc).
HOLD
A short press on the HOLD key freezes the display.
A long press on the key activates or deactivates the Bluetooth link.
MAX
AVG
MIN
A short press on the MAX AVG MIN key opens the MAX AVG MIN mode; the current values continue to be
displayed.
A second press displays the maximum value.
A third press displays the average (mean) value.
A fourth press displays the minimum value.
A fth press results in a return to the rst-press condition and display of the current values
A long press is used to exit from the MAX AVG MIN mode.
In the MAP mode, presses on the MAX AVG MIN key display in turn the maximum, average (mean), and minimum
of the MAP measurements.
