Where:
# represents the ranges 1, 2, 3, 4, 5.
The LED brightness level for each range is as follows:-
Range 1 = Low
Range 2 = Medium
Range 3 = High
Range 4 = Super
Range 5 = Ultra
Description
This command uses a pre-selected exposure time designated Range1, Range2 etc. For low
light or dim LED's use Range 1 and for brighter LED's use higher ranges. The higher ranges
lead to faster test times because the exposure time is shorter.
This command instructs the LED Analyser to read and store the Colour and Intensity of all the
LED's positioned under the fibers using a fixed range.
The range setting must be specified. The data is stored until the power is removed or another
capture# command is issued. When completed the Analyser will transmit the character OK
on the receive line to the transmitting device (i.e. the PC).
Example:
The PC transmits capture# to the LED Analyser and the LED Analyser sends OK to the PC to
acknowledge that the command is completed.

There are 5 manual capture ranges each with an intensity output range of 0 to
99,999. Feasa recommends that the UUT readings should be in the 55K to 85K range
for the best stability.
