2.1.1 MEASUREMENT SYSTEMS
The units of measure stated in this document are listed below:
1 gamma = 1 nano tesla
1 tesla = 10,000 gauss
cm = in x 2.54
lb = kg x 2.2
degrees F = [°C x 1.8] + 32
degrees C = [°F - 32]/1.8
u' = 4x/(-2x + 12y + 3)
v' = 9y/(-2x + 12y + 3)
x = (27u'/4)/[(9u'/2) - 12v' + 9]
y = (3v')/[(9u'/2) - 12v' + 9]
nits = cd/(m 2 ) = Ft-L x 3.426
lux = foot-candle x 10.76
: 225 lux
Chroma 2250 signal generator or equivalent, directly
Connected to the monitor under test.
Minolta CA100 photometer, or equivalent
Maximum (unless otherwise specified)
Typical
110Vac or 220Vac
:
: 20 ± 5˚C (68 ± 9˚F)
