Setting An Offset For The Calculation Of The X Any Y Chromaticity Coordinates - MICRO-EPSILON colorCONTROL MFA-5 Instruction Manual

Operation
5.1.3
There are three ways to store an offset for the calculation of the x and y chromaticity coordinates:
1. MICRO-EPSILON Eltrotec GmbH provides a calibration service for the colorCONTROL MFA-5. In doing
so, your LEDs to be tested are tested on our premises using a verifiably calibrated spectrometer in a stan-
dardised process.
In the next step, the chromaticity coordinates tested by the colorCONTROL MFA-5 are adjusted to the test
values of the spectrometer. This can be done during the installation of the firmware using a non-volatile
stored offset.
2. It is also possible to integrate the colorCONTROL MFA-5 in an existing test system via initialisation of the
COM port and a command set, see Chap.
An offset for each LED to be tested can also be stored in this application case using the commands
setxoffset#+-0.xxxx b or setyoffset#+-0.xxxx b.

3. An offset can also be stored using the supplied MICRO-EPSILON LED Check software.
This memory, as in point 2, is also a volatile memory and is lost after switching off the power supply or after a
Reset Board command in the software.
The following steps explain how an offset is stored using the software in the colorCONTROL MFA-5:
It should be emphasised for the MICRO-EPSILON LED Check software that the display of stored offsets and
modifications in the menu window Measurement settings or Settings for Sensor is not applied and
displayed until performing a test for the software. For further details about setting and modifying an offset,
see Chap. 4.2.4.
