colorCONTROL MFA-5
A 3.6 How Precise is the colorCONTROL MFA-5?
The color chip used enables a color depth with 12 bit resolution for each color; this corresponds to
236 = 68,719,476,736 representable colors. The colorCONTROL MFA-5 therefore achieves an unsurpassed
repeatability of the color and intensity.
CIE color system: White x = ± 0.0015, y = ± 0.0015
RGB color:
Red (630 nm) ± 3 nm
Green (540 nm) ± 4 nm
Blue (630 nm) ± 3 nm
A 3.7 How Long Does the Measurement of LEDs Take?
The "Standard Capture" command takes approx. one second. However, there are many capture modes avai-
lable; the exposure can be freely set between 1 ms and 10,000 ms to guarantee optimum testing. Very short
exposure times are sufficient for very bright LEDs while longer exposure times must be provided for dark
LEDs.
A 3.8 How Long Does the Test of 25 and More LEDs Take?
All the LEDs to be tested are captured simultaneously with the "Capture" command. The time actually needed
is basically specified by the darkest LED. Up to 20 checkpoints can be connected with each other using col-
orCONTROL MFA-5 + 3x colorCONTROL MFA-5-M system networks.
A 3.9 Can Flashing or Pulse Width Modulated (PWM) LEDs be Tested?
Yes, see Chapter 6.2.2.3 , command "Capturepwm".
A 3.10 Can 7-segment Displays be Tested?
Yes, provided you treat each segment as an individual LED and mount an optical fiber over each segment.
The displayed numerals from 0 to 9 can thus also be tested.
At least 7 checkpoints are needed for this (1x colorCONTROL MFA-5 + 1x colorCONTROL MFA-5-M + as-
sembly kit MFA-10).
A 3.11 Can Bi-color or Tri-color LEDs be Tested?
Yes. Each color must be tested separately.
