3.2.2 Setting mode and time
Overview of selectable modes, their descriptions, and times
Setting the mode
Briefly press the MODE button (mode is indicated in the display) to set a mode.
Selectable modes: response time [µs/ms/s], exposure time [1/x s], frame rate [Hz], rolling
shutter [µs/ms/s].
Setting the time
Use the rotary knob to set a time/frequency in the different modes.
Setting the LEDs running direction
Figure 1
To set the running direction, press and hold the
MODE
button until the display's "Set direction"
is shown. Change the direction by turning the rotary knob. There are eight directions for the
response and exposure time modes, and there are also four directions for the rolling shutter
mode. The running direction is indicated on the right side of the display. For instance, the
indication "12/34" (Figure 1) means the LEDs start from the left top edge of the LED matrix and
run to the right top edge. It then jumps to the left of the second top line, runs from left to right,
and continues to the bottom of the LED matrix. The indication "12/12" means that a column of
10 LEDs starts from the left and runs to the right.
Display and LED-array brightness
The brightness of the display can be modified by using the rotary knob. Press and hold the
rotary knob until the message "Set brightness" and "LED xx LCD xx" are shown on the display.
