4.2.2 Conditions for power measurements
Power measurements shall meet the following requirements:
a) power measurements shall be taken from a point between the power source and the UUT. No uninterruptible power supply (UPS) units shall be connected between the power meter and the UUT. The power meter shall remain in place until all ON mode, standby mode and OFF mode power data are fully recorded;
b) power measurements shall be recorded in watts as directly measured (unrounded) values at a rate of greater than or equal to 1 reading per second; and
c) power measurements shall be recorded after voltage measurements are stable to within 1%.
4.2.3 Dark room conditions
Unless otherwise specified, the iluminance measured at the UUT screen with the UUT in OFF mode shall be less than or equal to 1.0 lx. If the UUT does not have an OFF mode, the illuminance shall be measured at the UUT screen with the UUT's power cord disconnected.
4.2.6 Battery operated products
For products designed to operate using batteries when not connected to the mains, the battery shall be removed for all tests. For UUTs where operation without a battery pack is not a supported configuration, the batteries shall be fully charged before the start of testing and shall be left in place for the test. To ensure the battery is fully charged, perform the following steps:
a) For products that have an indicator to show that the battery is fully charged, continue charging for an additional 5 hours after the charged indicator is present.
b) If there is no charge indicator, but the manufacturer's instructions provide a time estimate for when charging this battery or this capacity of battery should be complete, continue charging for an additional 5 hours after the manufacturer's estimate.
c) If there is no indicator and no time estimate in the instructions, but the charging current is stated on the UUT or in the instructions, terminate charging 1 hour after the calculated test duration or, if none of the above applies, the duration shall be 24 hours.
4.2.7 Accuracy of input signal levels
When using analog interfaces, video inputs shall be within±2% of referenced white and black levels.When using digital interfaces, the source video signal shall not be adjusted for colour, or modified by the tester for any purpose other than to compress/inflate and encode/decode for transmission, as required.CAN CSA C383-13 pdf download.
