KL 2500 LED – Operating instructions

2.4 Light intensity setting

The brightness can be adjusted continuously by
turning the light intensity setting knob (1). The
brightness setting is shown in the LCD display (12)
as a percentage.
Every stop position of the setting knob increases or
decreases the value by 5.0%.
Maximum brightness is reached at a setting of
100.0%. When the brightness control is set at
0.0% there is no more intensity, i.e. the lamp is off.
Attention: Please note that when the brightness
control is set at 0.0% the instrument is not
switched off. When the instrument is switched on
the green control light (11) is lit. Switch off the KL
2500 LED by pressing the on/off switch (2) once
(see point 2.3
The LCD display (12) indicates the LED energy consumption as a percentage. The control is linear,
whereas the illumination power of the LEDs is not proportional to the current consumption. For this
reason the change in intensity in the upper control range (> approx. 50.0%) is not particularly great,
whilst in the lower control range accordingly greater.
To ensure sensitive adjustment especially in the lower control range, press the light intensity setting
knob (1) to achieve fine-tuned control in increments of 1.0% or extra-fine-tuned control in
increments of 0.1%. If the light source is in "extra-fine-tuning mode", "FINE" is shown in the LCD
display (12). To reset the light source to "standard setting mode" press the light intensity setting
knob (1) again; "COARSE" is shown in the display (12).
The indicated brightness can be stored away by long pressure >2sec of the light intensity setting
knob (1) at any time by hand. In the LCD display (12) appears for a short time "SAVED". If a
brightness value was stored in this manner, the light source KL 2500 LED starts with this saved
brightness value after switching off and on no matter whether the light source was in a "fine-tuning
mode " before switching off.
