1 Applications
The SECULIFE IM 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 SECULIFE IM 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 SECULIFE IA 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 ). The accuracy class for luminance meters has been defined in the Standard Specification DIN 5032, Part 7. The SECULIFE IM 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 SECULIFE IM 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.

3 Functioning of the SECULIFE IM
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 SECULIFE IM 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 SECULIFE IM
4.1 Switching on – Making Measurement Press the on/off key and the SECULIFE IM 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 SECULIFE IM 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/m2 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 SECULIFE IM 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 SECULIFE IM to the measuring function.
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. 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 SECULIFE IM will return to the measuring function. When the memory is completely filled, the display will show „FLL“.

Mem
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
value stored 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. An acoustic signal confirms
„value stored in memory“. In the
display the measurement value stored is indicated for a few seconds alternating with the number of the memory location. Subsequently the SECULIFE IM 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 in the display alternating with the measurement value stored in the memory.
By pressing any one of the other keys or when for about ten seconds no further memory data will be recalled with the Range keys, the SECULIFE IM will return to the measuring function.
Mem
4.4.5 Mem-Clear“ – Clear memory The SECULIFE IM must be in function „HOLD“. When pressing simultaneously the Range keys, you clear the complete measuring data memory. The cancelling is confirmed by an acoustic signal and three dashes in the display.
5 USB Port Standard Software The SECULIFE IM 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 SECULIFE IM contains, among other information, a Standard Software which allows you to start the PC operation immediately. More details about the PC operational functions are also available on that CD-Rom.
