1 Applications
The MAVO-MONITOR Luminance Meter is a handy, easy to use and high precision measuring instrument.
It allows the accurate measurement of the luminance in cd/m² or fL. The MAVO-MONITOR is ideally suited
for contact measurements with the light measuring probe placed direct on luminous or backlighted
surfaces (monitors, TV sets,light boxes, light panels). When combined with the MAVO-SPOT Attachment
(optional accessory), it can be used for spot metering the luminance at a distance from 34 cm to ∞, the
measuring angle being 1 degree. (Monitors, with the ambient light being taken into consideration in the
measurement - lighting and illumination of work stations, streets, airports, museums, projection screens).
The light sensor is color corrected, i.e. its spectral responsitivity has been matched to the spectral photonic
vision of the human eye (V λ). The accuracy class for luminance meters has been defined in the Standard
Specification DIN 5032, Part 7. The MAVO MONITOR fully complies with the requirements of Class
B.Consequently all the important types of light can be measured with high precision, without the necessity
to apply additional corrrection factors. The MAVO-MONITOR is provided with a data memory with 100
measurement value locations, which can be read and processed direct with the keys and display, but also
through the integrated USB Port and the standard software provided with the instrument.
cd/m² = Candela per m² 1 cd/m 2 = 0.2919 fL = 0.0929 cd/ft 2
fL = footLambert 1 fL = 3.426 cd/m 2 = 0.3183 cd/ft 2
1 cd/ft2
= 10.76 cd/m 2 = 3.142 fL

3 Functioning of the MAVO-MONITOR
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 MAVO-MONITOR is pressed, the instrument will be
switched 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 (cd/m² or fL) in the display will blink and indicate that the continuous operation mode is
on.
4 Using the MAVO-MONITOR
4.1 Switching on – Making Measurement
Press the on/off key and the MAVO-MONITOR is immediately in the measuring mode and is measuring at
the rate of 2 times per second. The instrument is in the function „AUTO“, i.e. the MAVO-MONITOR 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 cd/m 2 or fL
Use the key cd/m2 fL to select the desired unit for the read-out – 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 MAVO-MONITOR 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 function allows you to measure even at very low light levels, where it would be difficult to
read the display. By pressing the HOLD key, the last value measured is held on the display to be read at
brighter light. Pressing the HOLD key again will return the MAVO-MONITOR to the measuring function.
The function HOLD is the basic function for all the memory functions.
