3.2.2 Setting mode and time
Overview of selectable modes, their descriptions and times
Setting the mode
To set a mode briefly press the
MODE
button (mode is indicated in the display).
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 message "Set direction"
will be shown on the display. Change the direction by turning of the rotary knob. There are eight
directions for Response Time and Exposure Time modes and 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 that the LEDs starts from the left top edge of the LED
matrix, runs to the right top edge, than jumps to the left of the second top line and runs again
from the left to the right and so on 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.
