SECTION VIIA TECH 2 MAIN MENU & LIVE PLOT
2005 Tech 2 User’s Guide VII - 7
Because of the nature of the LCD (Liquid Crystal Display), you will experience some contrast variance.
When the temperature of the Tech 2 increases the display will brighten slightly. As the temperature of the
Tech 2 decreases, the display will darken. This variance is a characteristic of an LCD screen and should
be considered normal operation.
The screen contrast control setting described above may not account for the entire variance of operating
temperatures. Set a default setting which is mid-range between the operating temperatures. Screen
contrast may be adjusted during any function by pressing the SHIFT key and using the up and down
arrows for adjustment. Periodic adjustments may be necessary, but settings outside of this application are
only retained during the current power-up session.
IMPORTANT
The Set Contrast Control tool option adjusts the permanent default contrast setting of Tech 2 display.
F1: Set Screen Contrast
Selecting F1: Set Screen Contrast reveals a Set Contrast Control screen (Figure VIIA-5) that instructs
you on how to set and save the screen contrast to optimize the tool’s visibility in your lighting conditions.
