1Applications
The MAVOLUX 5032 illuminance and luminance meters are handy, easy to use and high precision measuring
instruments. They allow the accurate measurement of the illuminance in lx or fc.
Combined with the Luminance Adapter, available as optional accessory, the Mavolux 5032 can also be used for
measuring luminance in cd/m² or fL.
The light sensor is color corrected, i.e. its spectral responsitivity has been matched to that of the human eye V(λ).
The accuracy of that V(λ) matching is the main difference between the two types Mavolux 5032 C and
Mavolux 5032 B.
The accuracy classes for illuminance meters have been defined in the Standard Specifications DIN 5032, Part 7.
(CIE 69) Consequently, the Mavolux 5032 C complies with Class C, Mavolux 5032 B complies with Class B
(CIE 69). Suitable cosine correction is integrated in the light sensor probe, so that oblique incident light will be
measured accurately. Consequently, the MAVOLUX 5032 C complies with Class C,
MAVOLUX 5032 B complies with Class B.
All the important types of light can be measured with high precision, without the necessity to apply any additional
correction factors.
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 measurement data memory with 100 locations, which can be read and
processed direct with 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/m2

3Functioning of the MAVOLUX
3.1 Preparation
First remove the snap-on cover and open the battery compartment at the back of the meter. Insert the battery
included with the meter (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 measurement data memory and also the preset
individual values will be maintained, even when the battery is changed.

3.2 Duration of Display – Continuous operation
If for approx. 4 minutes none of the keys of the MAVOLUX is pressed, the instrument will be turned off
automatically. During the last 4 seconds before automatic switch off an acoustic signal will sound. By pressing any
one of the keys, you can override the Automatic Switch Off.
When the instrument is switched off, the values stored in the data memory and also the preset individual values will
be maintained.
You can override the automatic switch-off, when switching on the instrument and simultaneously keep the HOLD
key depressed. The measuring unit „lx / fc“ in the display will blink and indicate that the Continuous Operation
Mode is on.
4Using the MAVOLUX
4.1 Switching on – Making Measurement
Press the on/off key and the MAVOLUX is in the measuring mode and immediately is measuring at the rate of
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
locked. Browsing 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 desired measurement unit lx or fc – cd/m² or fL
Use the key lx/fc to select the desired 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.
4.3 Overload Display
When exceeding one of the measuring ranges
„OL“ (Overload) appears in the display.
4.4 Memory Functions
The MAVOLUX is provided in addition to the „Display Hold“ also with a memory for data up to 100 measurement
values.
This function allows several measurement operations in the field and read-out at a later time. The data stored in the
memory will be maintained, even when the instrument is turned off or the battery is changed.
4.4.1 „HOLD“ - Display Hold Function
The display HOLD memory in the MAVOLUX allows you to measure at a certain time and hold a measuring value
on the display by pressing the Hold key.For example at a very low light level it is difficult to read the display but by
pressing the Hold key the indicated value is held on the display to be read later.
When pressing the key HOLD again, the function HOLD is cancelled.
The function HOLD is the basic
function for all the memory
functions
4.4.2 „Mem“ – Storing measurement value in memory
The measurement value to be memorized is locked by the Hold key in the display.
By pressing the key Mem you will enter the value to be stored in the next free
memory location.
The display indicates the stored measurement value alternating with the number of
the memory location for a few seconds. Subsequently, the MAVOLUX will return to
the measuring function. When the memory is completely filled, the display will show
„FLL“.

4.4.3 „Mem-Edit“ – Deleting a value in memory and entering a new value
The Mavolux offers the function „Mem Edit“ for correcting a stored value in the
memory. Measure again, press the Hold key and the new value is locked. Then by
pressing one of the range keys, you can browse through the memory.
At the memory location to be corrected press now the key
Mem. In the display the measurement value stored is
indicated for a few seconds alternating with the number of
the memory location. Subsequently the MAVOLUX will
return to measuring function.
4.4.4 „Mem Recall“ –Data memory Recall
Start in the function „Measuring“ and press the key Mem.
The last memory location filled will be indicated first.
Press one of the range keys to browse through the data memory. The current
memory location is indicated as 01-02... in the display alternating with the
measurement value stored in the memory.
To return to the measuring mode just press any one of the
other keys or when for about ten seconds no further
memory data will be recalled with the Range keys, the
MAVOLUX will return to the measuring mode.
4.4.5 „Mem-Clear“ – Clear memory
The MAVOLUX must be in function „HOLD“.
When pressing simultaneously the Range keys, you clear the complete
measuring data memory. The cancelling is confirmed in the display
by three dashes.
5USB Port – Standard Software
The MAVOLUX is equipped with a USB Port which allows the meter to be connected to a PC with the USB cable
(supplied).
The CD Rom supplied with the MAVOLUX contains, among other information, a Standard Software which allows
