## represents the Fiber Number and is a number in the range 01 – 20.
0.xxx represents the y Chromaticity offset value (±0.000 – 0.300).
Description
This set command is used to set an offset to the displayed y Chromaticity value. The limit of
the offset is ±0.300 which means values must be in the range ±0.000 – 0.300. This
command is useful when the user wishes to set the y Chromaticity to be the same as that
specified by the LED Manufacturer. The default value of the offset is 0.000. The offset is
stored in non-volatile memory and will remain at the programmed setting until changed by a
new
Setyoffset command.
This put command is used to set an offset to the displayed y Chromaticity value. The limit of
the offset is ±0.300 which means values must be in the range ±0.000 – 0.300. This
command is useful when the user wishes to set the y Chromaticity to be the same as that
specified by the LED Manufacturer. The default value of the offset is 0.000. The offset is
stored in RAM memory and will remain at the programmed setting until changed by a new
Setyoffset command or power OFF.
Example:
The PC transmits setyo0.050 to the LED Analyser to instruct it to set the y offset on
Fiber 01 to +0.050.
