H.1 Cal / Wedge Printout
The numbered definitions below (1, 2, 3, etc.) are keyed to the numbered elements of the
sample calibration printout shown in Figure H-1.
1 = Date/time of calibration printout, instrument serial number, and hardware option
number.
2 = NVM Data
The numbers that appear in the printout represent the current calibration values stored
in Cal/Config Data for each item listed, for this particular instrument. A brief definition
of each item is given below, followed by a table that lists the acceptable tolerance range
for each item.
Proj . . . . . . .
represents voltage
*
(left column) and intensity
*
(right column) of the
projection lamp when a white stimulus is projected.
Bowl
. . . . . . represents voltage
*
and intensity
*
for the white bowl lamps.
Blue
. . . . . . . represents voltage
*
and intensity
*
of the projection lamp when a blue
stimulus is projected.
Yellow
. . . . . represents voltage
*
and intensity
*
for the yellow bowl lamp
Right Mode

Shutter

Aperture
. . . microsteps of positioning for each of the 5 positions of the aperture
wheel
Color
. . . . . . microsteps of positioning for each of the 5 positions of the color wheel

Voltage and intensity are expressed here as relative numbers, not actual units of voltage or
intensity (such as volts or foot-lamberts). Typically, any high round number (e.g., 30000) that
appears here in the printout is the default value for a parameter that has not been calibrated.
It is possible but highly unlikely that a calibrated value would fall precisely at a high round
number.
3 =
Voltage drop across projector lamp when white stimulus is projected, and when blue
stimulus is projected.
