5.1 General.
1. All specification must be met over line voltage range of 90V
AC
to 264V
AC
50Hz / 60Hz, unless otherwise
specified.
2. Operating temperature range is 0
o
C to 40
o
C with a relative humidity of 10% or less to 80%.
3. The monitor must be operational in a usable state within 30 minutes after turn-on.
4. All signal levels are measured assuming termination at the monitor’s input jacks or in its characteristic impedance.
5. All controls must have excess range (no control may be left at an end stop when proper alignment is completed).
6. The monitor is not required to meet specs during the following but must tolerate, without damage to the LCD or
circuits, any sequence or combination of power on and off, signal on and off, erratic, wrong frequency or noisy
inputs while at any possible unplugging of power or signal, settings of user accessible controls likewise, the
monitor should survive extended periods of operation with line voltage reduced below the specified minimum.
7. An isolation transformer should be used when performing alignment and tests, Portions of the power supply board
are hot ground, The remaining boards are cold ground.
8. Ambient condition:
8.1 Illumination: In usual inspection of electric performance and mechanical performance, it sh
a
ll be 150 ~
260lux.
8.2 Environmental noise: Less than 60dB.
8.3 Interference of EMI: The inspection shall be carried out in the place where a set is not disturbed by external
unnecessary electric wave and magnetic field.
8.4 Temperature: 24 ± 2
o
C.
8.5 Humidity: 65 ± 20%.
