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).

.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.
PAGE 4
.4.2 „Mem“ – Storing measurement value in memory Hold 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. An acoustic signal confirms „value stored in memory“. The display indicates the stored measurement value alternating with the number of the memory location for a few seconds. Subsequently, the MAVO-MONITOR will return to the measuring function.

4.4.4 „Mem Recall“ –Data memory Recall Mem 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 in the display alternating with the measurement value stored in the memory.

.2 - - Optional Accessories MAVO-SPOT (ordering no. M494G) Attachment For precision spot metering of the luminance, non contact, at a distance from 34 cm to ∞, with measuring angle of 1 degree. The ambient light is being taken into consideration in the measurement. The light sensor is color corrected, i.e. its spectral responsitivity is adapted to the photonic vision of the human eye. (V λ) according to DIN 5032, Part 7, Class B.
