Description
This command allows the User to specify the
exposure range
#
and an
averaging factor
@@
when testing PWM LED's. Select the
exposure range # (1-5) to match the
Intensity
of the
LED's.
The Analyser tests these LED's by taking a number of readings and averaging the
results. A larger Averaging factor will lead to more stable results but increased Test Times.
The
averaging factor
@@ is a number in the range 1-15. If this number is omitted from the
command the default value is 07.
This command instructs the LED Analyser to read and store the Colour and Intensity of all the
LED's positioned under the fibers. 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).

OK
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.
