2 Operation
First install the included battery (one 1.5 V mignon,
alkaline-manganese cell per IEC LR6) into the bat-
tery holder. Open the snap-fastener at the battery
compartment at the back panel of the measuring
instrument. Be certain that the battery is correctly
poled when inserted according to the poling indica-
tion in the battery compartment.
2.1 Battery Test
Battery testing is performed automatically. If the “ ”
symbol appears at the display, the battery must be
replaced.
2.2 Taking Measurements
Switch the measuring instrument on by pressing the
“on/off” key.
After the instrument has been switched on, auto-
matic measuring range selection is always active.
The currently selected measuring range can be
locked by briefly pressing the „Auto
↕
“ or the
„Range“ key (range hold). Browsing up or down
through additional measuring ranges is accom-
plished by briefly pressing the scroll keys in a
repeated fashion. If both the „Auto
↕
“ and the
„Range“ keys are pressed and held simultaneously,
the instrument is returned from manual to automatic
measuring range selection.
2.3 Special Functions
After the MAVOLUX 5032C/B has been switched
on, the “auto-mode” is always active, i.e. the mea-
suring range with the best resolution is selected
automatically, and the display is refreshed at a fre-
quency which is equal to the measuring rate of the
A-D converter (approx. 2.5 measurements per sec-
ond).
Hold Key
When the hold key is activated, the current mea-
surement value is frozen at the display.
The hold function is cancelled if the key is activated
a second time.
MAX Key
Maximum illumination or luminance can be deter-
mined by activating the MAX function, after which
the highest detected value is stored to memory.
The MAX function is cancelled if the key is activated
a second time.
lx/fc Key
The “lx/fc” is used to select the desired unit of
measure, either lux or footcandles. When one of the
luminance attachments is screwed to the sensor
(see chapter 3, page 6), the instrument will automat-
ically switch over to reading the corresponding units
of cd/m
2
or fL.
