Lamp Intensity Calibration (LCA)
This control is used to calibrate (correlate) the intensity feedback mechanism to footlamberts. Note the minimum/
maximum power are used to pick two points on the curve. These points will not stay consistent over the life of the
lamp, but the conversion algorithm will extrapolate the conversion beyond the range of the two end points. Foot-
lamberts for minimum/maximum power are converted to integer by multiplying 100 because serial command pro-
tocol does not support floating point number.
calibration.
SUBCODE DESCRIPTION OF USE
Set footlamberts at maximum lamp power, the value should be (footlamberts * 100)
MAXF
Set sensor value at maximum lamp power
MAXS
Set footlamberts at minimum lamp power, the value should be (footlamberts * 100)
MINF
Set sensor value at minimum lamp power
MINS
Not available
NONE
EXAMPLES:
(LCA+MINF 10) Set 10 footlamberts as measured brightness at minimum lamp power
(LCA+MINF?) Get footlamberts on minimum lamp power
(LCA+MINS 5000) Set 5000 as reading value from the light sensor at minimum lamp power
(LCA+MAXF 17) Set 17 footlamberts as measured brightness as maximum lamp power
(LCA+MAXF?) Get footlamberts at maximum lamp power
(LCA+MAXS 15000) Set 15000 as reading value from the light sensor on maximum lamp power
LUT CLUT Control (LCT)
Set Look up Table (LUT) Color Look Up Table (CLUT) file for the specified channel. The CLUT is used during
color processing in the electronics.
SUBCODE DESCRIPTION OF USE
Replace xxx with the channel number. Valid range is 101 - 164.
Cxxx
Select CUT for the current channel.
NONE
EXAMPLES:
(LCT+C108 "9x9x9") Use PCF file "9x9x9" on channel 108
(LCT+C108?) Get LUT-CLUT file name on channel 108
(LCT?L) List all entries of LUT-CLUT control
Lamp Intensity Calibration (LEN)
