EST-Z Series User's Manual Application Preparation, Manual No.CP-SP-1088E

Handling Precautions

• When the instrument is powered up after having been left in a cold

location, the display will remain dark for about 10 minutes. When the

instrument is used in a cold environment, the display change takes time

and an after image remains. These are only characteristics of the LCD

and not a malfunction.

• Visibility and color of LCD differ according to the view angle, this is not a

malfunction.

• There may be some permanently lit/unlit pixels, this is not a fault.

• When displaying straight line, for example, on LCD display, a linear like a

shadow may appear on its extension. This is not a malfunction. (This is

called a cross-talk, and occurs depending on the displayed objects.)

• Interference fringes like a rainbow may appear on the touch switch

surface, but this is not a malfunction. (This is called a Newton-ring, and

appears according to the little change of the gaps between touch

switches.)

• The areas around the perimeter of the screen may be whitish, but this is

not a malfunction. (This is due to the backlight.)
