1 Applications
The MAVOLUX 5032 illuminance meters are handy, easy to use and high precision measuring
instruments. They allow the accurate measurement of the illuminance in the unit lx or fc.
Combined with the Luminance Attachment, available as optional accessory, the MAVOLUX 5032 can also
be used for measuring luminance in the unit cd/m² or fL.
The light sensor is color corrected, i.e. its relative spectral responsivity has been adapted to that of the
human eye V(). All the important types of light can be measured with high precision, without the necessity
to apply any additional correction factors.
The accuracy of that V() adaptation is the main difference between the two types MAVOLUX 5032 C and
MAVOLUX 5032 B. The quality classes for illuminance meters have been defined in the Standard
Specifications DIN 5032, Part 7. Consequently, the MAVOLUX 5032 C complies with Class C, MAVOLUX
5032 B complies with Class B (DIN 5032, part 7 and 8).
The light collector with circular orifice in the photometer head has integrated cosine correction, so that
oblique incident light will be measured accurately.
Both MAVOLUX types allow measuring very high intensity light (daylight, headlights) without additional
accessories. Especially the MAVOLUX 5032 B having an initial sensitivity of 0.01 lx is ideally suited for
measuring extremely low light intensities, such as emergency lighting.
The instruments are provided with a measuring value memory with 100 data spaces, which can be read
and processed directly by the keys and the display but also through the integrated USB Port and the
Standard Software supplied with the meters.
lx = Lux 1 lx = 0.0929 fc
fc = footcandle 1 fc = 10,76 lx
cd/m² = Candela per square meter 1 cd/m2 = 0,2919 fL
fL = footlambert 1 fL = 3,426 cd/m

3 Functioning of the MAVOLUX
3.1 Preparation
First remove the snap-on cover of the battery compartment at the back of the meter. Insert the battery
included in the delivery contents (1.5 V size AA, IEC LR6) in the battery compartment.
Care should be taken to place the battery correctly according
to the polarity indications “+“ and “-“ in the battery compartment.
When the battery warning symbol () appears in the display,
the battery must be replaced.
The values in the measuring data memory and also the preset
individual values will be maintained, even when the battery is changed.
3.2Duration of Display – Continuous Operation
If for approx. 4 minutes none of the keys of the MAVOLUX is pressed down, the instrument will be turned
off automatically. When the instrument is switched off, the values stored in the measuring data memory
and also the preset individual values will be maintained.
You can override the automatic switch-off, when you switch on the instrument and simultaneously keep
the HOLD key pressed down. The measuring unit „lx / fc“ in the display will blink and indicate that the
Continuous Operation Mode is on.

4 MAVOLUX Operation
4.1 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 one of the range keys, one of the
measuring ranges can be set. Scrolling up or down through additional measuring ranges is accomplished
by briefly pressing one of the range keys. If both keys are pressed and held simultaneously, the instrument
is returned to „AUTO RANGING“.
4.2 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 additional
Luminance Attachment (please refer to 6.2 – Optional accessories), this key also selects the measurement
unit for luminance cd/m² or fL – candela per square meter or footlambert.
4.3 Overload Display – 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.

4.4 Memory Functions
Hold
In addition to the display buffer storage, the MAVOLUX has also been provided with a memory space for
up to 100 measured values.
This function allows the user to make several measurements in the field and then to view them later. The
data stored in the memory will be maintained, even if the meter is turned off or if the battery is changed.
4.4.1 „HOLD“ - Display Hold Function
The MAVOLUX has been equipped with a Display HOLD Function in order to enable you to make
measurements in very low light conditions and to read them out later in brighter light conditions.
The latest measurement will be buffer-stored in the display by striking the HOLD key. Then “HOLD” will
appear in the display. Pressing down the HOLD key again will prompt the MAVOLUX to return to the
measuring function.
The function HOLD is the basic function for all the memory functions.
