lead.
➁Backlit liquid crystal display
- Main display: numeric value
3½ digits or OL error code
- Symbols:Low battery
Last value measured
klux / kfc Value of unit displayed
MAX Maximum value (C.A. 811)
PEAK Peak value (C.A. 813)
➂Dual function pushbutton:
Short press: activates/deactivates display backlighting

➅3-way switch:
-OFF :Switches the instrument off
-lux :Lighting measurement unit
-fc :Anglo-Saxon lighting measurement unit
(footcandles)
3. USE
3.1 Procedure
1. Place the sensor flat on the surface where you wish to
measurethelighting.Moveawayfromthe measurementarea
to avoid influencing the measurement (possibility of shade).
2. Toswitchtheinstrument on:select oneofthe 2measurement
units with ➅, the measurement appears on the display;wait
until the displayed value is stabilised and, with ➄, choose
the appropriate measurement range.
3. Configure the instrument according to the type of
measurement to be taken using special function keys ➃or
➂(see § 3.2).
4. Record the measured value once the display has stabilized.
The instrument is switched off by returning the cursor of ➅to
the OFF position.
Note: If the lighting to be measured is not within the
measurementrange, theinstrumentwilldisplayOL;inthiscase,
press briefly on ➄a few times to choose the appropriate
measurement range.
3.2 Special functions
See § 2. Description
HOLD:when you press on this key, the instrument freezes on
the last value measured, this function is deactivated
when the instrument is switched off
MAX:the instrument (C.A 811) displays the maximum value
measured;this functionisusefulwhenthelightingvaries,
it is deactivated when the instrument is switched off or
the key is pressed again.
PEAK: the instrument (C.A 813) displays the peak value
measured;thisfunctionis usefulwhen thelightingvaries
very rapidly, it is deactivated when the instrument is
switched off or the key is pressed again.
