The MAVO-SPOT 2 is a high-precision measuring instrument with a measuring angle of 1°. Luminance

measurements at distances of 1 meter to infinity can be performed with the instrument. The MAVO-SPOT 2

features mirror reflex optics with a 15° field of view, a sharply marked 1° measuring circle at the center and a

focusing mechanism.

The close-up lenses available as accessories make it possible to shorten measuring distance to 34 cm. Luminance

can be measured directly at displays with the help of the attachment for contact measurements.

The light sensitive sensor is color corrected, that is its spectral sensitivity is matched to the spectral luminous

efficiency of the human eye in daylight V(). Classification of luminance meters is specified in DIN 5032, part 7, and

in DIN EN 13032, appendix B. The MAVO-SPOT 2 fulfills class B requirements in accordance with these

standards. The instrument is equipped with a measured value memory module with up to 1000 memory locations

which can be read out and processed either directly via the keypad and display, or via the integrated USB port with

the help of the included standard software.

Suitable for the measurement of, for example:

Monitors in consideration of ambient light,

for example approval and consistency testing in the field of medical

technology in accordance with DIN 6868-57 and IEC 61223-2-5 (quality

assurance guideline dated 20 Nov. 2003)

Street, tunnel and airport illumination

Illumination at sports facilities

Contrast measurements at workstations (ASR)

Illumination in museums and public buildings

Projection screens (inspection for uniform illumination)

Warning: Do not perform measurements with the instrument pointed towards sun.

Eye damage may result, and the light sensor could be damaged as well.

3.1 Preparation

Inserting the Batteries

The battery compartment is located at the front of the grip. Push the battery compartment

cover in the grip down. Remove the battery holder with the help of the tab. Replace the

batteries assuring correct polarity (+ and -). Insert the battery holder into the instrument

and close the battery compartment with its cover.

Approximately 5000 measurements can be performed with a new set of batteries.

Attention: Use new batteries only in accordance with IEC LR6 (2 ea. 1.5 V, AA).

Self-Test

After inserting the batteries, the microcomputer executes a self-test. All of the elements

included in the display panel appear at the display during this test. The display test can

be aborted by pressing any key.

Battery Indicator

The MAVO-SPOT 2 requires two 1.5 V AA batteries (alkaline manganese). The capacity display indicates the

current battery power level. Measured values are retained in memory when the batteries are changed.

= The batteries are fully charged.

= The batteries are partially discharged –be prepared to replace them.

= The batteries are depleted and must be replaced as soon as possible.

The Protective Filter

Screw the included protective filter or one of the close-up lenses or the attachment for

contact measurements (optional accessory) onto the lens of your MAVO-SPOT 2.

Either the protective filter, a close-up lens or the attachment for contact

measurements (optional accessory) must always be used.

3.2 Changing the Default Settings

You can change the default settings for your MAVO-SPOT 2. The settings are selected with the

help of the DIP switches inside the battery compartment underneath the battery holder. The

default settings can be changed as desired in any combination.

Stand. - Comp. DIP switch –selection of standard or compact operating mode

The operating mode can be changed from standard to compact with the Stand. - Comp. DIP

switch. You can perform measurements and save measured values in the compact mode –the

calculation and correction values functions (Corr) are disabled; programmed correction values

are nevertheless taken into account (see also section 4.4 on page 16).

cd/m² - fL DIP switch –selection of a of a unit of measure: cd/m² or fL

The desired unit of measure, namely candelas per square meter or foot-lamberts, can be selected with the

cd/m² - fL DIP switch.

GOSSEN Foto- und Lichtmesstechnik GMBH 9

Linear - Page DIP switch –selection of 1000 individual memory locations or subdivision into groups (see

also section 3.5.2 on page 19)

You can select either consecutive storage of 1000 measured values or subdivision into 10 groups with 100

measured values each with the Linear - Page DIP switch. The pages are identified as P-01 through P-10.

Memory content is deleted automatically when the memory location display mode is switched.

4 Operation

4.1 Switching the Instrument On

The MAVO-SPOT 2 can be switched on by pressing any key.

The measuring instrument is activated and the display panel is illuminated.

The last measured values appear at the display (display memory).

4.1.1 Display On-Time

If none of the keys at the MAVO-SPOT 2 are activated for a period of 30 seconds, the instrument is switched off

automatically, i.e. the display goes blank but measured values and individual settings are stored to memory.

10 GOSSEN Foto- und Lichtmesstechnik GmbH

4.2 Measurements

Press the key to select the Lumi function.

Look through the eyepiece on the MAVO-SPOT 2, and sharply focus

your measuring field with the focusing mechanism at the lens. Now

align the measuring circle reflected into the viewfinder to the point to be

measured. This point should be uniformly illuminated, and as large as

possible relative to the measuring circle.

Press the key and read the measured value.

4.2.1 Overflow / Underflow Display

If the measuring range is exceeded, “----” appears at the display.

If the measuring range is fallen short of, “0.00” appears at the display.
