Operation Modes
For safety reasons the LED can be enabled /switched on only if one of the three
operation modes (Constant Current, PWM or External Control) is selected. This
'Safety Mode' can be disabled (see chapter
for more details).
It is possible to leave the active mode when the LED is switched on and enter the
main menu. However, the LED has to switch off before you can enter another
operation mode. This can be done while the main menu is selected by pressing the
LED button.
The last selected operation mode will be saved. After switching on the DC2100
again this operation mode will be automatically the active mode. All settings are
saved and validated after a shut off.
3.1.2.1
Constant Current Mode
The 'Constant Current Mode' provides a constant non-modulated LED current.
The actual current is displayed and can be set directly with the multi-control knob. No
confirmation is necessary. The 'Ok' button has no functionality within this mode. The
LED is switched on or off with the LED button. The LED current can be changed
when the LED is off as well as when it is in operation. This allows to increase or
reduce the brightness of the LED. The current limit is displayed at the bottom of the
screen.
Return to the main menu with the 'ESC' button.

Constant Current Mode
The faster the multi-control knob is turned, the greater is the adjustment ratio of the
current. If you move the knob slowly you can set the current with a 1mA resolution. If
you move it faster the resolution will increase up to a 200mA resolution.
