3 MAVOLUX Operation
3.1 Switch On – Make Measurement
Press down the
on/off
key and the MAVOLUX will start up in measuring mode and will immediately be
measuring at 2 times per second. The instrument is in the function „AUTO“, i.e. the MAVOLUX will
select the best suited measuring range for the existing light level. By pressing the
Auto
or
Range
key,
one of the measuring ranges can be set. Scrolling up or down through additional measuring ranges is
accomplished by briefly pressing the
Auto
or
Range
key. If both keys are pressed simultaneously, the
instrument is returned to „AUTO RANGING“.
3.2 Selecting the Measurement Unit lx or fc – cd/m² or fL
Use the key
lx/fc
to select the required unit for the read-out – lux or footcandle. With the optional
Luminance Attachment (chapter 5.2), this key also selects the measurement unit for luminance cd/m²
or fL – candela per square meter or footlambert.
1 lx
= 0.0929 fc
1 fc
= 10.76 lx
1 cd/m² = 0.2919 fL
1 fL
= 3.426 cd/m²
3.3 Overload and Zero Point Indication
When exceeding one of the measuring ranges „OL“ (Overload)
appears in the display.
The zero point indication may be achieved by putting the protective
cap over the light collector of the photometer head.
