Page 10 of 16

f)

After all testing has been completed under the high-illuminance conditions, the above stepsa) through e) shall be repeated with a target illuminance equal to 10 ± 1.0 lux.

F) Test Conditions for Products with an Occupancy Sensors Enabled by Default:
1) Products with an Occupancy Sensors shall be positioned facing away from any testers, or havethe sensor covered or otherwise disabled to be in an open position for the duration of the test.

1) Luminance measurement shall be performed using eithera) A contact meter; orb) A non-contact meter.
2) All luminance and illuminance meters shall be accurate to ± 2% (± 2 digits) of the digitallydisplayed value.
3) Non-contact luminance meters shall have an acceptance angle of 3 degrees or less.
The overall accuracy of a meter is found by taking (±) the absolute sum of 2% of the measurement
and a 2 digit tolerance of the displayed value least significant digit. For example, if an illuminancemeter displays “200.0” when measuring a screen brightness of 200 cd/m2, 2% of 200 cd/m2 is 4.0
cd/m2. The least significant digit is 0.1 cd/m2. “Two digits” implies 0.2 cd/m2. Thus, the displayed value
would be 200 ± 4.2 cd/m2 (4 cd/m2 + 0.2 cd/m2).The accuracy is specific to the illuminance meter andshall not be considered as tolerance during actual light measurements.
H) Measurement Accuracy for All Products:
1) Power measurements with a value greater than or equal to 0.5 W shall be made with anuncertainty of less than or equal to 2% at the 95% confidence level.
2) Power measurements with a value less than 0.5 W shall be made with an uncertainty of less thanor equal to 0.01 W at the 95% confidence level.
3) All ambient light values (measured lux) shall be measured at the location of the ABC sensor on
the UUT with light entering directly into the sensor and showing the default image that appears
as-shipped.
4) Ambient light values shall be measured within the following tolerances:a) At 10 lux, ambient lighting shall be within ± 1.0 lux; andb) At 300 lux, ambient lighting shall be within ± 9.0 lux.
