4.4 Video recording rate / Frame rate

This mode makes the frame rate measurement of video recording devices possible. The LED-
Panel is set to the frame rate mode "Frame rate" and is being recorded on the camera. The
frequency of the LED-Panel must now be counterbalanced with the rotary knob until the lower
row of LEDs stops blinking on the camera display. The LED-Panel has now matched the frame
rate of the camera. The manual frequency scan should be started at the lowest level because
the frame rate frequency harmonics also cause the LEDs to stop blinking.
