8.1 Electrical Instructions
1. General points
1.1 During the test and measuring, supply a distortion free AC mains
Voltage to the apparatus via an isolated transformer with low
internal resistance.
1.2 All measurements mentioned hereafter are carried out at a normal
mains voltage (90 - 132 VAC for USA version, 195 -264 VAC for
EUROPEAN version, or 90 - 264 VAC for the model with full range
power supply, unless otherwise stated.)
1.3 All voltages are to be measurement or applied with respect to
ground,unless otherwise stated.
Note: Don‘t use heat-sink as ground.
1.4 The test has to be done on a complete set including LCD panel
in a room with temperature of 25 +/- 5 degree C.
1.5 All values mentioned in these test instruction are only applicable
of a well aligned apparatus, with correct signal.
1.6 The letters symbols (B) and (S) placed behind the test instruction
denotes
(B): carried out 100% inspection at assembly line
(S): carried out test by sampling
1.7 The white balance (color temperature), has to be tested in subdued
Lighted room.
1.8 Repetitive power on/off cycle are allowed except it should be avoided
within 6 sec.
